A protective device that is used to protect the electrical power system from surges caused by lightning is known as surge arrester. It includes two terminals like high voltage and ground. Once an electric surge travels through the surge arrester from the power system, then a huge voltage current can travel to the insulation directly otherwise to the ground terminal to protect the system from damage.

Not all surge arresters protect systems from lightning. While lightning current arresters (Class 1) are used to protect against direct lightning surge currents, surge arresters (Class 2) protect equipment from induced surges in electrical wiring. Surge arresters and lightning current arresters from DEHN offer reliable protection against these hazards. And there are many kinds of surge arresters such as Distribution Surge Arrester, Station Surge Arrester, Line Surge Arrester, etc. Different surge arresters have to be equipped with different Metal Oxide Varistors like 5kA Varistor, 10kA Varitor, etc.

How Does a Surge Arrester Work?

The purpose of a surge arrestor is to protect insulation/components from high DV/DT that peak at instantaneous values that are in excess of the breakdown of the insulation or component. Lightning is one common cause of voltage surges. Another common cause is switching in an inductive circuit.

It is possible to capture the occurrence of a voltage surge. Some surge arresters are equipped with "surge counters" that capture the fact that the arrester has discharged current. It is also possible to use other phenomena (sound measurement, light measurement, electric field measurement, etc.) to capture the occurrence of a discharge. Meteorologists routinely capture and record lightning discharges using both ground-based and satellite-based instruments.

It is also possible to capture and record voltage surges, but here the technology gets complicated. A common issue is that a voltage surge is inherently a high-frequency phenomenon, and in order to capture and record (ie, quantify) the event, the measurement system must have a high-frequency response. The kind of instruments that are commonly applied for fundamental frequency voltage measurements don't have sufficient frequency response to accurately capture and record high-frequency voltage transients. They may be able to capture the occurrence of the event, but it is not always possible to accurately quantify the event using those devices.

A surge arrester is a device that protects electrical power systems from damages caused by lightning. A typical surge arrester has both a ground terminal and a high-voltage terminal. When a powerful electric surge travels from the power system to the surge arrester, the high voltage current is sent directly to the insulation or to the ground to avoid damaging the system.

How to Install?

Generally, the installation of surge arresters can be done close to an electric meter to defend the electrical system used in a residence or building from the power surge effects which are occurring from the outside.

It protects other electrical devices that are connected to the power source, however, they cannot provide whole protection from surges that occurs from defective wiring otherwise the overall working of electrical appliances used in homes or in offices.

In chemistry, we call the separation of solids and liquids filtration. In the filtration operation, filter paper is indispensable to filter out solids and liquids.

What is Filter Paper?

The filter paper for laboratory use is one of the common lab consumables. It is normally round in shape and made from cotton fiber and used to filter components. The functional principle of the filter paper is separating the substances through them. They are normally made from fiber, which is the reason that there are keyholes on them. The keyholes resist the big solid particles and provide pathways for the liquid particles. And the most common usage for a filter paper nowadays is as a Printing Filter Paper.

The different kinds of filter papers having different characters are made by different technics. So, what are the main factors in the filter paper selection? There exist four: hardness, capacity, filtration efficiency, and applicability.

Filter Paper Structure

The filter paper is directional. The front side of the filter paper has loose fibers; the mesh surface of the filter paper has tight fibers. The front pores are in the shape of a bell mouth, and the pores become smaller along with the thickness of the filter paper. The thickness of the filter paper is about 0.35～0.5mm, and the particle size of dust particles varies from ranging from a few microns to tens of microns.

Filter paper filtration not only has the function of a screen but also has the function of deep filtration; the side magnification shows that the filter paper is a multi-layer structure. The front of the filter paper should face the direction of airflow, the screen surface should be in the direction of the gas flow. Color lines are drawn on the screen surface to facilitate user identification and prevent mistakes; if the front and back directions are wrong, the filter element is in use, and dust is stored. Ability is reduced by 30%.

As for different materials for paper or film, there is a widely used material that has to be mentioned. It is Cellophane Paper. What is Cellophane or Cello? Cellophane wrap has long been used to encase edible treats like lollies, nuts and baked goodies, however Cellophane wrapping is especially used in floristry to wrap fresh and artificial .

Originally marketed as packaging material in America in 1924, cellophane wrap was the most popular choice of film until the introduction of Polypropylene (PP) in the 1960s. PP quickly became the preferred clear packaging film choice mainly due to its low manufacturing costs and high resistance to many chemicals. Therefore, when referring to cellophane wrap it would encompass both true cellophane (made of wood pulp and cotton) and BOPP (bi-axially orientated polypropylene which means that the PP has been shaped).

What's more, more and more materials are used for different purposes nowadays, such as Non Woven Fabric, Wax Paper, Bopp Film for Flowers Packing and so on.

The steady advancement of technology affects every industry, but none more so than the printing industry. Since the Printing Press was invented there has been a constant effort to improve productivity and efficiency. Because of this demand, the printing industry has always been on the leading edge of the technology curve.

The latest advancement to our industry is Computer to Plate technology, affectionately known as CTP. While CTP is easy to understand in theory, the subtle nuances to the different manufacturer's technologies and the plethora of information by others about how to install and configure your new CTP Plate Making Machines make printers hesitant to take the plunge into this new technology. In actuality, CTP Machines are easy to use and efficient. It saves money and time because it skips an entire step when compared to the old CTF (computer to film) process.

What is CTP?

CTP (Computer to Plate) is a streamlined process of print production. Streamlined in that takes a finalized file from a computer and outputs it directly to a plate. The plates are made from a variety of materials ranging from aluminum to polyester. Once the plate is imaged, it can be used on the press. In the old CTF process the file was sent from the computer to a film processor, then the film image was transferred to the photographic plate so the plate could be used on the press. In the CTP process, the film step and its associated chemicals and bio hazard are completely eliminated.

When you remove the film step and the associated chemicals, you are saving on film and chemical costs, the chemical smell is greatly reduced, and you are producing high quality plates at a faster rate. Since we all know that time = money, what this means is that with each plate you produce, you are saving on the equipment, labor and supply costs that your company has when it produces a print piece for a client.

Because CTP Plate Making Machines use a new and straightforward technology, it stands to reason that there would be a variety of ways to implement it. This variety has emerged in the multiple technologies available for CTP, which are Violet, Thermal, Ink Jet and Poly Plate.

What's the difference in the technologies?

Since violet and thermal are currently the major players in the CTP market I will focus primarily on them. Both Violet and Thermal use laser diodes to transfer the image onto the plate. The difference in the two types of lasers are the color of the laser and the wavelength of the light they emit. Violet has less lasers than a thermal machine and because of this has a lower acquisition cost. If you compare the quality of a violet and a thermal system, you would see that the thermal system can produce better quality than a violet system can. A thermal system can produce line screens exceeding 300lpi, whereas a violet system maxes out at 300lpi. That said, anything over 300lpi is actually overkill on the vast majority of projects.

Due to the fewer number of lasers in the machine, violet plates are light sensitive. This requires either a safelight environment (typically a yellow light) or the auto-load option that most manufacturers have can be used. Conversely, thermal plates can be used in normal daylight conditions.

As to speed of production, violet produces plates faster, but thermal machine manufacturers are trying to cut the time gap with their newer technology. It seems odd though that speed would be a major factor here because compared to the old CTF process, thermal is still much faster.

Except for CTP, there are some other print machines may used like Label Printing and Cutting Machines, Digital Printing and Finishing Machines. They have to work with some Other Printing Materials such as Laser Imagesetters, Printing Plates including Offset Printing CTP Plates and Other Printing Plates, Printing Consumables, etc.

Keeping kids active is an ongoing challenge, especially in the era of smartphones and video games. Although many families build playground equipment in their backyards, some climates are too rainy, cold, or hot to allow year-round use outdoors.

Indoor gyms are an excellent solution for kids, and they can be customized to suit their age and interests. It's easy to install a few basic pieces in the corner of a playroom or the basement.

The focus for kids gym equipment needs to be a balance of fun, safety, and developmentally-appropriate activities. Some equipment choices depend on the child's age, but many items can grow with the child for at least a few years. Here are eight great home gym ideas to keep your children happy and healthy.

Small Trampolines

Trampolines are both easy and fun for children of all ages to manage. Children under the age of five will require supervision to make sure they consistently jump vertically, but once they have the hang of it, they can use it on their own.

Trampolines help build leg and core muscles and are also a good test of kids' balance. If you have more than one child using the gym, make sure they understand that only one child uses each small trampoline at one time. You may want to buy a second one if needed to avoid conflict, but make sure to keep them a few feet away from each other to avoid collisions.

Climbing Ropes

Thick ropes with a few knots in them are perfect for kids who love climbing. They provide a good workout for the entire body, especially if you increase the distance between knots over time.

Keep in mind that climbing ropes can be a challenge for kids of any age who lack the upper-body strength to do them at first. Kids may need lots of prompting to practice using it if they can't manage it the first few times. However, once they hit second or third grade, they should manage the rope like a pro.

Monkey Bars

Monkey bars are generally easier for kids than climbing ropes because kids have to move themselves sideways, not upward, and can use their swinging motion to build momentum. However, monkey bars still build excellent upper body strength and hand-eye coordination.

Monkey bars for children up to third grade should be no higher than 5 ft. off the floor to help prevent serious head injuries. If you decide to build your own monkey bars, make sure the bars are spaced no more than 1 ft. apart so your children can swing across safely.

Gymnastics bars are great tools for channeling children's energy into something productive and healthy. Children are known to have an endless supply of energy, and a gymnastics bar gives them the needed platform to use their energy exhaustively. Our team extensively reviewed the available gymnastics bars to bring you the finest gymnastics bars in 2022. These bars were selected based on criteria like ease of use, flexibility, and stability. Gymnastics bars are not only meant for kids that have an interest in gymnastics, but also for kids who need something to play around with at home. Kids do not require elaborate gymnastics skills to use them, but you should still always be mindful of your child's safety. Gymnastics bars create a balance between fun and exercising for kids. Also, they make for a great birthday present.

The Shiwei gymnastics bar allows kids to have fun without worrying about weight. It supports up to 330 lbs of weight and can extend to 5 feet in height, hence it can be used by almost any kid regardless of their weight or height. It’s made of fiberglass material that is lightweight yet sturdy, allowing you to move the bar easily and providing long-lasting durability. Also, it comes in both pink and blue color options, so you can pick a color that you believe would appeal to your child the most.

The Tepemccu gymnastics bar features a foldable design that makes it easy to move the unit around and also requires little storage space. The bar is easy to set up, and the heights are adjustable to five varying lengths to suit the user (maximum height at 50.8″). Plus, it supports up to 140lbs in weight, making it suitable for use by most kids. There are four anti-slip foam rings at the base that provide enhanced stability to the structure, prevent slippage, and protect the floor against scratching.

How It Works

Pliés, relevés, and sauté jumps don’t just look graceful, the ballet moves also lengthen and strengthen muscles and burn calories.

ballet-inspired classes like Pure Barre, Bar Method, and Balletone are a popular workout trend that incorporates moves from ballet, Pilates, and yoga to upbeat music.

Many gyms offer ballet-inspired fitness classes, and barre studios offer classes for overall conditioning as well as targeted workouts for abs, thighs, or glutes. There are even “barre light” classes for beginners.

You don’t need a tutu or ballet slippers. Instead, dress in comfortable workout clothes and show up to the 60-minute classes prepared to use the ballet barre to do the movements your teacher shows you.

Some classes also use small balls, resistance bands, and hand weights to do floor work. The low-impact workout focuses on proper alignment.

The classes blend cardio, strength training, flexibility, balance and core conditioning in a total body workout that targets the hips, glutes, abs, and arms.

Intensity Level: Medium

The emphasis on proper alignment, balance, and core engagement means the classes move at a slower pace. You might not leave a ballet-inspired class drenched in sweat, but you’ll feel the burn after a class thanks to moves that target specific muscle groups.

Areas It Targets

Core: Yes. You'll do a combination of ballet positions and Pilates moves to target the abs.

Arms: Yes. Classes include exercises like military presses, lateral arm raises, and triceps lifts to work the arm muscles.

Legs: Yes. Expect to perform movements like pliés, dégagé, leg lifts/extensions, and other ballet-inspired moves that target the legs.

Glutes: Yes. Targeted moves like glute raises help tone the backside.

Back: No. Ballet-inspired workouts target the whole body but do not target the back muscles, except for those that are part of your core.

Type

Flexibility: Yes. This ballet-inspired workout will gently improve your flexibility.
Aerobic: No. The barre moves are too slow to give you an aerobic workout. So unless you're in a class that includes exercises off the barre that gets your heart rate going, don't count this as cardio.
Strength: Yes. Some ballet and barre classes use weights and resistance bands, and others use your body weight to strengthen and tone.

Sport: No. It’s not a sport.
Low-Impact: Yes. There is no jumping or bouncing in barre classes, so the workout is easy on the joints.

Riding a stationary exercise bike is an efficient and effective way to burn calories and body fat while strengthening your heart, lungs, and muscles.

Compared to some other types of cardio equipment, a stationary bicycle puts less stress on your joints, but it still provides an excellent aerobic workout.

Read on to learn more about the benefits of a stationary bike workout, and the kinds of workout plans that can help you reach your fitness or weight loss goals.

1. Boosts cardio fitness

Cycling is an excellent way to get your heart pumping.

Cardiovascular or aerobic workouts, such as cycling, strengthen your heart, lungs, and muscles. They also improve the flow of blood and oxygen throughout your body. This, in turn, can benefit your health in a number of ways, including:

• improved memory and brain functioning

• lower blood pressure

• better sleep

• improved blood sugar levels

• a stronger immune system

• better mood

• lower stress levels

• more energy

2. Can help with weight loss

Depending on the intensity of your workout and your body weight, you can burn more than 600 calories an hour with a stationary bike workout. This makes indoor cycling an excellent workout option for burning calories quickly.

Burning more calories than you consume is the key to weight loss.

3. Burns body fat

Working out at a high intensity helps to burn calories and build strength, which, in turn, can lead to fat loss.

A 2010 studyTrusted Source found that indoor cycling, combined with a low-calorie diet, was effective in reducing body weight and body fat in the study’s participants. It was also effective in lowering cholesterol and triglyceride levels. The participants cycled for 45 minutes three times per week, and they consumed 1,200 calories per day for 12 weeks.

4. Provides a low-impact workout

A stationary bike workout is a low-impact workout that uses smooth movements to strengthen bones and joints without putting much pressure on them. This makes it a good workout option for people with joint issues or injuries.

Your ankles, knees, hips, and other joints can be put under a lot of stress when running, jogging, jumping, or doing other high-impact aerobic exercises.

Because your feet don’t lift off the pedals with a stationary bike, this option is kinder to your joints, but it still provides a challenging and effective workout.

When looking to purchase a cycle bike, you have a wide variety of options to choose from. One of the best factors for narrowing your selection is determining the type of resistance best for you whether that be magnetic resistance, contact resistance, or air resistance. In this article we'll go over the specifics of each type of resistance, so you can make the best choice for you.

Magnetic resistance uses magnets to create tension against the flywheel. Unlike contact resistance, the magnets don't actually make contact with the flywheel. Instead, the magnetic force applies varying degrees of resistance as the magnets gets closer or further away from the flywheel. Magnetic resistance can be adjusted either by twisting a micro-tension knob or electronically through set levels on a digital monitor.

Magnets create incredibly strong forces, meaning the resistance you'll feel with a magnetic resistance bike is strong, although it can always be adjusted if you're looking for an easier ride. A magnetic resistance cycle bike is sure to provide challenge throughout your fitness journey.

Steel plate construction is generally double the speed of other strengthened solid construction since it abstains from tying rebar and building structures nearby. The equal plate gatherings can be built rapidly in specific off-site creations. The technique has superb quality in light of the fact that the steel is on the outside, where tensile forces are often greatest. The steel construction industry requires numerous kinds of steel in all sizes. Steel plates can be found in structures, bridges, tall structures and construction vehicles. Steel plates can be made by enormous steel manufacturing plants or littler, progressively specific plants. Steel plates are one of the numerous sorts of steel that can be created, different sorts incorporate steel bars, sheets, sections, rolls, and the sky's the limit from there. Steel plates are regularly utilized for structural and construction applications, pressure vessels, marine and offshore equipment, and military applications. The grade, components and parameters of a steel plate are additionally utilized.

Steel plate is a material regularly used to make metal items. Fabricated to various thicknesses and widths, the steel plate is sliced and welded together to make the last item. There are various sorts of the plate, for example, pure and high-carbon steel plates. A few sorts of plate steel are utilized in the construction of buildings structures while others are utilized in the making of regular things, for example, wood heaters, and not all that ordinary things, for example, transport bodies. Steel plate is regularly alluded to as level steel. Steel plates are utilized to fabricate present-day shipping so as to make destructive safe high-quality. Run of the mill employments of steel plate includes general manufacture, basic individuals, tall structures, spans, stockpiling tanks and blenders. The flexibility and strength of steel plates make it the ideal material for use in household machines that incorporate stoves and fridges. Applications for steel plate depend intensely on the points of interest of the task. This essentially implies certain evaluations are more fitting to specific assignments than others.

Steel plate construction is a quick strategy for building constructing heavy reinforced concrete items. At a steel fabricator, gatherings are built. Every gathering has two equal plates together with welded stringers. The assemblies are moved to the place of work and put with a crane. The plates are welded with the goal that they structure equal dividers joined by stringers. At long last, the space between the plate dividers is loaded up with concrete. Steel plate is both erosions and scraped areas safe. It is made to a lot more extensive scope of thicknesses than conventional steel sheets. Plate steel is basically utilized in applications where super-basic structure and indestructible solidness is required. Stainless steel plates are additionally simple to shape, have a spotless and alluring appearance, and are moderately light yet entirely tough. These are likewise quite moldable without settling on quality, making it perfect for use with a ton of things. Steel plate is usually used to strengthen foundations and maintain mass units of weight like extensions. Then again, it gives a base to the development of bigger materials and non-serviceable parts.

Since the construction time is about half, sunk interest costs for heavy construction projects are about half when this technique is utilized. The department of defense regularly requires higher-grade steel plates for use in military vehicles and structures. Steel businesses with military agreements fabricate steel as indicated by the reasons and measures set by the department of defense and its different offices, for example, the army, air force and navy. Military steel plates are utilized in tanks, jeeps, trucks and ground vehicles, just as helicopters, planes and other airplanes. The navy utilizes this steel for shipbuilding and maritime fix. Our steel plate is perfect for the accompanying applications: general basic articles, sports arenas, buildings and high rises, bridges and different establishments, reinforcing prerequisites, various overwhelming hardware and earthmovers and bulldozers.

Temperature Control Compatibility: Yes

Nichrome is a common material for pre-wrapped RDA coils, but you won't see it often in the world of sub-ohm tanks. When you're shopping for sub-ohm tank coils, kanthal and stainless steel are the materials you're most likely to see. Compared to kanthal, stainless steel has a slightly lower resistance and a slightly faster ramp-up time for a given wire gauge. Unlike some of the other non-kanthal coil materials, people generally find that stainless steel doesn't introduce any off flavors that require getting used to.

Stainless steel also has the benefit of being an easy material to work with from a tooling standpoint. You can stamp stainless steel into shapes that wouldn't be possible to create with kanthal. In the mid-2010s – before mesh coils became the standard for cloud chasing – manufacturers were experimenting with unusual coils such as “notch coils,” which were cylinders with notches cut out of them. Shapes like that would only be possible with stainless steel.

One of the most interesting features of stainless-steel coils is that they're the only vape coils that you can use for either wattage-based or temperature control vaping. For temperature control, all that you need is a vaping device that supports stainless-steel coils – which almost all mods built in the last few years do – or allows you to enter a custom TCR.

Compared to the other two coil materials used for temperature control vaping – nickel and titanium – stainless steel has a significantly lower TCR. That means the material's change in resistance as it's heated is not as easy to measure. Some vape mods may not be completely accurate when estimating the temperature of a stainless-steel coil.

The last thing to consider before you buy a vape tank using stainless-steel coils is that stainless steel does contain a small amount of nickel. If you are allergic to nickel, you'll probably want to avoid stainless steel and stick with kanthal coils.

Aluminum is corrosion resistant and and virtually maintenance free. It has unbeatable strength to weight ratio when compared to other metals, and weighs in at roughly 1/3 as much as iron, steel, copper, or brass. Aluminum plate has heat conductivity better than any other common metal and conducts electricity comparable to copper products.

Aluminum is non-toxic and can be used in food preparation equipment. It is non-combustible (does not burn) and has a reflective nature, making it suitable for light fixtures. Some end uses for all grades of aluminum include transportation, food packaging, furniture, electrical applications, building, construction, machinery and equipment. It is interesting to note that aluminum is the most abundant metal element in Earth's crust and makes up about 8% by weight.

Trim coil PVC comes in rolls of aluminum sheeting that are usually 50 feet long and 3 feet wide. It is used to create custom trim that covers exterior window frames, door frames, rake boards, gables and other trim items. The PVC is a plastic coating that prevents fading and oxidation. PVC-coated trim coil comes in white or a variety of colors and is used to create a maintenance-free home exterior.

Examine the existing trim on the house and create a bend pattern with a scrap piece of PVC trim coil. This involves bending a thin strip of metal to match the shape of the current wooden trim.

Roll 12 feet of PVC trim coil out onto a hard surface and separate it from the remainder of the coil by cutting in a straight line with the razor knife.

Mark the width of the PVC coil stock with a pencil in 1-foot sections.

Cut along each 1-foot mark with the razor knife so that three sections are created. Each one will measure 1 foot wide by 12 feet long.

Use the trim pattern to mark each bend across the width of one PVC coil trim strip. Flatten the pattern and use the indentations as a guideline. Mark outer bends on the top side of the coil stock and inner bends on the bottom side. Mark in three places, at each

Place the marked PVC coil strip in the coil brake. This is a special tool used to bend a piece of PVC coil strip into a custom piece of trim. It is 12 feet long and mounted on a table or on saw horses. Many equipment rental stores rent brakes by the day or week.

There are many unique values provided by stainless steel threading rod that make it an extremely useful construction and industrial project material. Our stainless steel raw materials and stainless steel threaded rod provide a bevy of benefits that will improve the overall scope of your project. Some of the more predominant benefits of stainless steel threaded rod, include:

• Corrosion Resistance - Lower alloyed grades resist corrosion in atmospheric and pure water environments, while high-alloyed grades can resist corrosion in most acids, alkaline solutions, and chlorine bearing environments, properties which are utilized in process plants.

• Fire & Heat Resistance - Special high chromium and nickel-alloyed grades resist scaling and retain strength at high temperatures.

• Strength-To-Weight - The work-hardening property of austenitic grades, that results in a significant strengthening of the material from cold-working alone, and the high strength duplex grades, allow reduced material thickness over conventional grades, therefore cost savings.

• Long Term Value - When the total life cycle costs are considered, stainless is often the least expensive material option.

Stainless Steel All Thread Rod Strength

Stainless steel threaded rod proves, when tested, to be stronger than most Grade 2 steels, but weaker than Grade 5 and Grade 8 stainless steel raw materials that have been hardened. Depending on the ratio of metals in the alloy, the definitive strength of most stainless steel grades will range from about 70 to 220 ksi. In addition, stainless steel threaded rod has less of a magnetic quality than standard steel.

Throughout history, scientists and inventors have created new solutions to everyday problems. Often times, the original method is only used until a superior solution comes along. At first we used a mechanical printing press, now your local print shop can process an order of 1,000 copies in a matter of minutes. The vehicles that we drive every day have seen vast improvements in safety and durability compared to previous models. In the same way, the silicone molding process has also undergone changes. Gumstock molding is a more traditional method, but Liquid Silicone has surpassed it in several ways, here are a few of the differences between the two types of silicone:

Liquid Silicone vs. Gum Stock

Gum Stock Silicone, or High Consistency Rubber (HCR) is a type of silicone that has the consistency of a thick putty or dough. It is often used in compression molding by placing the silicone into an open air molding press to form products. This process is fairly labor intensive compared to Liquid Injection Molding, especially when you are creating a product that requires specific customization.

On the other hand, Liquid Silicone has a consistency similar to petroleum jelly and it is made using a two-part system that is mixed as it is used. Liquid Injection Molding makes it much easier and less expensive to create custom features. At Si-Tech, we use silicone injection molding for all of our customers because it offers many distinct advantages.

Advantages of Liquid Silicone

Customization

Liquid Silicone Injection has made the process of customization much easier compared to Gum-Stock Silicone. Because liquid silicone is injected into two part molding system, customization is simple. Insert molding is achieved by having two molds, one mold to make the inserts such as colored keys, clear windows, or light pipes. Once the inserts are molded, they are placed into the keypad mold.

Durability

Liquid silicone uses a cross-link bond, making keypads more durable than gum-stock. As keypads undergo significant use, liquid silicone keypads have held up much better over time.

Time & Cost

Overall, Liquid silicone is a far less labor-intensive process, which means it is also less expensive. The main difference is that the cure time for liquid silicone is about 1/3 less than gum stock. Due to the way the different materials are processed, it can be much more time efficient to use liquid silicone molding – saving you time and money.

At SiTECH, we only use liquid silicone for all of our products, allowing us to be more dependable in duplicating our processes. We have made silicone products for many industries, and we would love to help you with your next product, contact us today!

Silicone lubricant has many forms, and even more uses to its name! As such, understanding when to use a silicone lubricant vs. when you should be using a dry lubricant for example is important in the effectiveness of the overall lubrication task.

Silicone lubricant can be used in the forms of an oil, which is non-reactive to most substances, maintains it's greasiness in extreme temperature conditions and does not oxidize, or a silicone spray which is not only water resistant, but also allows you to lubricate those hard to reach places like mechanisms or bearings.

This article will explore when to use Silicone lubricants specifically, the main uses of a silicone lubricant, knowing what materials to use a silicone lubricant on as well as how to waterproof using a silicone lubricant.

The main uses for silicone spray lubricant

As we mentioned earlier, silicone lubricant spray uses are plentiful. Whether you're a professional tradesman, handy man, or someone who uses tools in your day-to-day life, you understand how important it is to keep your tools and equipment working in top condition. Part of that means keeping your tools well lubricated and clean.

A silicone lubricant spray is an excellent product to use on tools because it of course lubricates, but also reduces friction and helps to drive out moisture. In fact, silicone lubricants are especially handy for wooden tools by preventing the wood from drying out and splintering.

On the other hand, silicone lubricant sprays can also be used on a wide range of home applications that you may not have thought of! Try lubricating the sliding door track with silicone spray to keep it moving, or extent the life of zippers on clothing, backpacks, sleeping bags, etc. and keep everything moving smoothly.

When to use silicone spray on rubber parts

The many uses of silicone spray don't stop there! In fact, the question isn't “what is silicone grease used for?” but rather “what isn't silicone grease used for?”. Silicone grease is especially effective at sealing rubber parts, but what's the best silicone spray for rubber? We'll get to that later.

Have you ever considered how many rubber parts are in your car? Or perhaps your dishwasher? Many day-to-day items that we've all come to rely on are comprised of thousands of rubber parts in varying shapes and sizes.

Rubber is everywhere!

Due to rubbers naturally slip resistant nature making it difficult to install, it's not unusual for rubber parts to slip during assembly where an o-ring may get twisted, a heater hose may not be fully inserted, or a gap appears in a waterproof seam. Coating rubber parts prior to assembly helps to avoid some of the aforementioned problems.

One of the most common uses of silicone spray on rubber parts is that of replacing car window rubber seals. To do so, simply remove the rubber with a flathead screwdriver, scrub the glue with a solvent and sand the metal.

How often should you use silicone lubricant?

We've answered the question of “what is silicone grease used for”, but how often should you use it?

Truthfully, the frequency at which you should lubricate your equipment depends on the equipment itself.

A high quality silicone lubricant will displace moisture, provide excellent lubrication for rubber, protect and extend the life of your equipment, doesn't allow dust, dirt, oil and grime to stick, as well as prevent parts from sticking and binding.

For optimal lubrication, most manufacturers will recommend that you keep on top of lubricating your tools and equipment and treating them before they become sticky, or worse – stuck! In fact, silicone is the most slippery of all lubricants, so it's a great choice for items that slide against one another.

A silicone lubricant can be used to lubricant metal, wood, rubber and plastic – however, dirt and dust tent to stick to the silicone lubricant, so make sure you use it sparingly or use a “dry” version in dirty environments.

Waterproofing parts with Silicone Lubricant

Now that we've discussed when to use silicone lubricant, the best lubricant for plastic parts, let's talk about waterproofing using Silicone lubricant.

Silicone lubricant is a great product for lubricating rubber surfaces, protecting and extending the life of your tools and equipment, does not allow dust, dirt, oil and grime to stick and of course prevents parts from sticking and binding. Further to this, silicone lubricant also displaces moisture to not only help prevent tools and machines from corrosion, but also helps to waterproof parts.

As the crusade for cleaner beauty products continues, skin care ingredients that were once considered standard are rightfully being called into question.

Take parabens, for example. Now that we know the once-popular preservatives are also potentially carcinogenic endocrine disruptors, beauty brands are removing them from their formulations and slapping “paraben-free” stickers on everything. The same for phthalates, sulfates, formaldehydes, and a whole host of other possibly dangerous ingredients.

While most experts support the removal of parabens, phthalates, sulfates, and more from skin care, one group of ingredients that’s made the “free from” lists is still up for debate: silicones.

On one side of the argument, you have those who say silicones make skin look healthier without actually contributing to its overall health.

On the other side, you have those who say silicones aren’t technically harmful, so there’s no harm in keeping them in skin care products.

Which side is science on? Well, both. Kind of. It’s complicated.

“Silicones are a group of semi-liquid substances derived from silica,” Dr. Joshua Zeichner, a board certified dermatologist with Zeichner Dermatology in New York City, tells Healthline.

Silica is the main component of sand, but that doesn’t mean that silicones fall under the “natural” umbrella. Silica has to go through a significant chemical process to become silicone.

Silicones are best known for their occlusive properties, which is a fancy way of saying that they form a barrier-like coating on the skin that’s resistant to both water and air. Zeichner likens it to a “breathable film.”

“Used medically, silicones have been provenTrusted Source to help heal wounds and improve scarring,” says Dr. Deanne Mraz Robinson, a board certified dermatologist and member of the Healthline advisory board.

“They have long been used in burn units because they can uniquely heal and protect while allowing the wound to ‘breathe.’”

Basically, their occlusive nature blocks lacerations from interacting with the outside environment, ensuring that the wound stays in its own little healing “bubble.”

“They also have a unique texture, giving skin care products a slick feel,” Zeichner says. This sums up the main role of silicones in serums and moisturizers: They make for easy application, lend a velvety texture, and often leave skin looking plump and smooth, thanks to that filmy coating.

Plastic isn’t all that fantastic. From the 500 plus years it takes to break down, to the increasing presence of microplastics in the ocean, there are so many reasons why we should reduce our use of plastic.

More households are now thinking about how they can find alternatives and use less plastic. One such alternative that has gained popularity is silicone.

But there’s an ongoing debate on the benefits of silicone vs plastic. Is silicone more environmentally friendly than plastic?

Is silicone plastic in a different form? And is silicone the answer to leading a more sustainable life?

Although silicone looks like plastic in many ways, its chemical composition is different.

Silicone is derived from silicon, which is a naturally occurring element. Silicon dioxide, for example, can be found in sand and quartz.

However, there is an important distinction between silicon and silicone.

Silicon is a naturally occurring element. Silicone is synthetic.

Silicone is made by combining the element silicon with other elements, such as oxygen. Silicone comes in many different forms, such as silicone oil, rubber and resin.

There’s lots to learn about the chemical makeup of silicone and how it differs to silicon. Live Science has more technical details about the differences between the two materials.

There’s a reason why the battle of silicone vs plastic has been quietly gathering pace. And why silicone has become so popular as an alternative to plastic over the years:

• Silicone can be moulded into a variety of shapes – like some plastics.

• Silicone is highly durable, making it great to use as an adhesive, sealant or as insulation.

• Silicone is capable of withstanding both high and low temperatures.

When it's time to lubricate plumbing components, it's essential to know what to use and what to avoid.

The market is flooded with products and each one promises a set of advantages. The two types of grease you will come across are – plumbers grease & silicone grease.

This can often lead to a comparison of plumbers grease vs silicone grease.

Plumbers grease is commonly used for non-consumed water sources in plumbing setups. In comparison, if there is potable water being ingested from the plumbing fixture, it’s recommended to use silicone grease. This is due to the toxic chemicals found in plumbers grease that should not be consumed by humans.

For the most part, both types of grease are effective at lubricating the fixture. However, it comes down to your safety.

This article will dive deeper into the subject by comparing plumbers grease vs silicone grease.

There are a handful of cables that transmit both audio and video signals. For years, coaxial video cables were one of the only choices for connecting video components. Coaxial video cables have that famous one-pin connector, sometimes called a stinger, that can either be pushed or screwed into place. Coaxial video cables are now mostly confined to outside connections, such as satellite TV or cable TV lines that come through the wall. A single coaxial cable carries both video and audio signals.

HDMI cables are an updated version of DVI. HDMI cables were also designed for use with HD components, but their connector is much slimmer, like a large USB cable. HDMI also includes HDCP copy protection. Manufacturers of HDMI cables tend to advertise their product as the only choice for connecting HD video components, but that's not true. DVI cables work equally well. However, if you're using an analog TV, all three work equally well [source: Cobalt Cable].

In Europe and the UK, the most popular dual-purpose cable is called SCART (Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs). SCART cables have fat, 21-pin connectors. In Europe, SCART cables do the work of RCA analog audio cables as well as composite, s-video and component video cables, but they can't carry high-bandwidth digital video or audio signals, such as those necessary for high-definition TVs. HDMI is the preferred cable in Europe for HD components.

FireWire, or IEEE 1394, cables are mostly associated with connecting devices to computers, but a few high-end home theater receivers and HDTVs now come with FireWire ports. FireWire is capable of carrying compressed MPEG-2 video and digital audio. You might use a FireWire cable to connect a digital video camera directly to your home theater system to show off some unedited footage.

To sum up, here are the cables that you would use for some common home entertainment systems.

Home stereo system (CD changer, stereo receiver, speakers):

• Lower-end: If you're playing regular CDs or MP3s, you'll only need RCA analog audio cables and speaker wire.

• Higher-end: If you want crisper digital audio, go for optical or digital coaxial cables and thicker speaker wire.

• Highest-end: If you want the unparalleled sound of DVD-audio in full surround sound, you'll need special DVD-audio cables and 12-gauge speaker wire.

Alternatively referred to as a cord, connector or plug, a cable is one or more wires covered in plastic that transmit power or data between devices or locations. The picture is an example of what the power cord may look like for your computer or monitor. The power cord is one example of thousands of other cables found in and around computers.

There are two main types of computer cables, a data cable and a power cable. A data cable is a cable that provides communication between devices. For example, the data cable (i.e., DVI, HDMI, or VGA) that connects your monitor to your computer allow it to display a picture on the monitor. Other popular examples of data cables include the CAT5, IDE/EIDE, SATA, and USB cables. A power cable is any cable that powers the device. For example, the power cord that connects to your computer and a Molex style cable inside the computer are both good examples of power cables. Below, is a listing of the most common types of cables found with computers and electronics and examples of devices that use them.

The wiring harness has been our core business since 1987. Sumitomo Electric Wiring Systems designs and manufactures the highest quality and most reliable wiring harness products for the automotive industry.

A wiring harness is an organized set of wires, terminals and connectors that run throughout the entire vehicle and relay information and electric power, thereby playing a critical role in “connecting” a variety of components. Power and information travel through this network much like the circulatory and central nervous systems of the human body.

As cars continue to provide advanced functions, their component parts increasingly require electronics to save space and meet other requirements. Experts at efficient design and configuring complex circuits, SEWS creates wiring harnesses that contribute tremendously to the development and advancement of car manufacturers around the world.

Medical cable assemblies are designed to connect medical and laboratory instruments and equipment. They transmit power and/or data and usually have an abrasion-resistant jacket that provides relatively low surface friction and mechanical durability. Many are designed with a high degree of flexibility to avoid kinking, and temperature-resistance to withstand autoclave sterilization. Some are disposable.

Like other cable harnesses, medical cable assemblies consist of individual cables that are banded into a single unit with connectors on at least one end. Medical cables typically comply with application-specific safety and regulatory standards, however, such as ISO 10993-1 for the biological evaluation of medical devices. If the outer jacket of a medical cable assembly will come into contact with a patient’s body, buyers should select products where biocompatible materials are used.

Types

There are three major categories of medical cable assemblies: equipment and sub-assembly interfaces, communication interfaces, and patient interfaces.

Equipment and sub-assembly interfaces are installed as original equipment and generally replaced only in case of retrofits or upgrades. Often, this type of cable assembly is used with nuclear imaging devices.

Communications interfaces use fiber optic, modular local area network (LAN), or serial cables. RS-232, RS-422, RS-423, and RS-485 cables are all used in medical applications.

Patient interfaces consist of durable cables that typically require replacement several times during the life of the medical equipment. Sometimes, these assemblies require performance upgrades. Alternatively, they may become damaged by age or repeated use.

Within the category of patient interface cables, there are several sub types.

Long-life patient interfaces include medical cable assemblies for ultrasound imaging and ECG diagnostic testing. These cables are durable, flexible and wear-resistant.

Limited-use interfaces include ICU and CCU monitor cables, as well as ECG diagnostic leads. These medical cables are damaged by repeated mechanical stress and exposure to cleaning chemicals, but are designed to last until scheduled replacement.

Use-only interfaces include catheters, electro-surgical devices, fetal monitoring cables, and neural simulator lead sets. They are sterilized and packaged in kits, and designed to be discarded instead of cleaned after use.

When selecting patient-interface products, buyers should consider the cost of replacement vs. cleaning these medical cable assemblies.

Connectors

The Engineering360 SpecSearch database contains information on several types of medical cable assembly connectors.

• BNC connectors are secure bayonet-style locking connectors, commonly used with A/V equipment, professional test equipment, and older peripheral devices.

• DIN connectors adhere to standards from Deutsches Institut für Normung, a German national standards body.

• Digital visual interface (DVI) connectors cover the transmission of video between a source and a display. DVI connectors may transmit analog (DVI-A), digital (DVI-D), or analog/digital (DVI-I) data.

• RJ-45 connectors are commonly used to transmit serial data.

Shielding

Cable assemblies may feature a type of electromagnetic shielding material, which is wrapped around the cable assembly underneath the outer jacket. Shielding serves to prevent electrical noise from affecting the transmitted signal, and to reduce electromagnetic radiation emission from the cable itself. Shielding is typically comprised of metal braiding, metal tape or foil braiding. A shielded cable assembly may also feature a special grounding wire known as a drain wire.

A technician may need to disassemble parts of the vehicle if they are attempting to access the wiring harness in question as it is difficult to reach. According to this example, installing a wiring harness can take no less than an hour or no more than 20 hours (i.e. if complications arise).

How Do You Replace An Engine Wiring Harness?

• Check the old and new connectors are the same.

• Strip the ends of the wires, then pull out the wire clips to replace the wiring harness.

• The wire ends should be twisted a little…

• Insulated connections should be coiled to wire harnesses.

• The Insulated Connector needs to be melted while the Wiring needs to be replaced.

• Using an electrical tape, you can tape the wire to it.

In order to better understand the function and form of the intake manifold gasket, let’s first examine the job of the intake manifold. Found on any vehicle with an internal combustion engine, the intake manifold sits on top of the engine and plays a key role in the combustion process.

Designed to run on three timed components, air mixed fuel, spark, and combustion; the internal combustion engine relies upon the intake manifold to help it breathe. Featuring a series of tubes, the intake manifold ensures that the air coming into the engine is evenly distributed to all the cylinders. This air is used during the first stroke of the combustion process.

The intake manifold also helps cool down the cylinders to prevent the engine from overheating. Coolant runs through the manifold to the cylinder heads where the coolant absorbs the heat and reduces engine temperature.

This brings us to the intake manifold gasket. Typically made from aluminized steel coated in a carbon-based rubber compound, the intake manifold gasket seals the intake manifold to the engine. High-quality intake manifold gaskets, such as Fel-Pro®, are constructed as one-piece with reinforced edges and linings around each port or runner opening. They must be resistant to decay caused by oils and coolants. The performance of your engine depends upon the quality of the intake manifold gasket.

If you notice any of the following symptoms, it could be a sign that your intake manifold gasket is wearing out. Consult your professional mechanic for a definitive diagnosis and repair.

• Coolant leaking from vehicle

• Engine overheating

• Green, red or yellow leaks under the car

• Check engine light comes on

• Engine starts to run rough

Engine valves are small, but they play a huge role in keeping your car running smoothly. If there is an issue with the valves, such as bent or burnt valves, it must be addressed immediately to prevent engine damage.

What are the symptoms of a bad exhaust valve or bad intake valve? How much will it cost to repair bent or burnt valves? Keep reading to learn the answers to these questions and more.

What are intake and exhaust valves?

Intake and exhaust valves are the final component in the valve train system. They are made of hardened metal that must withstand the extreme conditions of the combustion chamber.

Intake and exhaust valves are responsible for controlling the flow of gases through the combustion chamber. Intake valves let air in, whereas exhaust valves let air out.

They are shaped to have a slim stem leading to a flatter face, with the intake valves often being larger than the exhaust. Each valve is designed to only move up and down, not side to side.

When a valve is closed, it sits tightly on the valve seat to stop the flow of air. But when it is open, it separates from the valve seat to allow air to flow through.

In many modern engines, each cylinder has two intake and two exhaust valves per cylinder.

The intake manifold gasket in your car’s engine keeps the various fluids from mixing and leaking. Learn here how to tell if your car has a bad gasket.

A car's engine creates power through the combustion of air and fuel. In most modern, fuel-injected systems, the air and fuel mix together inside of the component known as the intake manifold. One end of the manifold consists of a single tube through which fresh air flows. The other end consists of multiple smaller tubes, each of which connect to one of your engine's cylinders.
Between the intake manifold and the engine block sits the intake manifold gasket. The intake manifold gasket seals off the small gap between the manifold and the engine, preventing air, coolant, and oil from leaking. Over time, the intake manifold gasket endures a lot of wear and tear. Eventually it may crack or warp in ways that allow leaks to occur.
Unfortunately, many car owners fail to recognize the symptoms that they may be dealing with a bad intake manifold gasket. If you would like to improve your skills at diagnosing this common engine problem, keep reading. This article explains three common symptoms that you may have a bad intake manifold gasket.

1. Misfiring Engine

Engine misfires involve one or more cylinders that fail to produce combustion in a given engine cycle. In other words, although air and gasoline flow into the cylinder, the mixture fails to catch on fire. Instead, the uncombusted mix passes out of your engine through the exhaust system. As a result, misfires lead to poor fuel economy and other problems.
Misfires may stem from a large number of problems, including poor ignition timing, excessively worn valves, and corroded spark plugs. Yet damaged intake manifold gasket tend to be one of the most frequently experienced causes of engine misfires. A damaged gasket often fails to create an airtight seal between the manifold and the engine.
This seal failure allows air that should be entering the engine to escape instead. Such a leak alters the engine's air–fuel ratio — one of the most important factors in promoting complete combustion. A bad enough leak may allow enough air to escape that combustion cannot occur at all.

2. Difficulty Accelerating

A leaky intake manifold gasket often makes it more difficult for your car to accelerate, even if the problem has not reached the point where it causes misfires to occur. Such power loss stems from the air leaking out of the intake manifold. Not only does this decrease the amount of air that makes it to your engine, but it also creates a vacuum leak for your entire air intake system.
A vacuum leak reduces engine air pressure, no matter how wide your throttle body opens. Thus, depressing the gas pedal often fails to generate the expected acceleration. Instead, your car seems to poke along at a fixed, sluggish rate.

If you think about it, there are things about your car that just don’t make sense. You’ve been told that more air is a good thing for power, that a cold air intake, more scoops, more vents, etc, are a great way to get more performance. Those are technically all true, but let’s walk that line of thinking back a bit by talking about a leaking or damaged intake manifold.

Can there be too much? The answer is that though more air is generally good, it’s important to know that unregulated air flowing into the engine can become a massive problem. Extra air coming into the engine that your car’s computer doesn’t know what to do with or where it came from leads to big issues for its air-fuel ratios which, you know, create the oomph that drives your ride.

So, a leaking intake manifold is bad. Damage to the component can mess with the coolant system and could cause stalling or worse. What is the intake manifold? Why is it important? Let The Drive’s blowhard editors drop some knowledge on you.

Symptoms of intake manifold failure can be difficult to identify as such, so it’s important that you are familiar with problems that might seem relatively minor, but which could be an indication of significant intake manifold issues.

• Difference in air-to-fuel ratio resulting in backfires and rough idlingF

• Milky-looking engine oil

• Coolant leaking onto the ground under the vehicle while it is stationary

• Regular or quick engine overheating

How Much Will Intake Manifold Repair Cost at a Garage?

Although the cost of replacing an intake manifold will vary depending on the make and model of the car, many estimates have the cost of the part at around $300, with much of the cost of the job coming from labour and time spent on it. This can be a significantly higher sum – as much as $900 – and in some cars it may not be worth going ahead with the job.

Can K-Seal Fix My Intake Manifold?

If there is a coolant leak then, in most cases, using K-Seal, K-Seal HD and K-Seal Ultimate will help to quickly and permanently stop the leak, saving you a lot of time and money. Use our simple stockist search facility to find a bottle and get back on the road.

What is an Intake Manifold?

An intake manifold directs the mixture of air and fuel to the right cylinder to be combusted so it can power the engine. Additionally, it conducts coolant through to the cylinders in order to reduce the temperature of the engine. The intake manifold is attached to the top of the engine by the intake manifold gasket, which has to be monitored as it is susceptible to cracking under the heat and pressure and allowing coolant or oil to escape.

Metal casting is the process of making objects by pouring molten metal into an empty shaped space. The metal then cools and hardens into the form given to it by this shaped mold. Casting is often a less expensive way to manufacture a piece compared with machining the part out of a piece of solid metal. There are many metal casting methods to choose from. What type of casting is most efficient depends on the metals used, the size of the run, and the complexity of the casting.

Before starting a production run, it is helpful to know some of the terms and methods from the foundry floor.

Casting terminology

Casting mold

A mold is a cavity in a material that receives liquid metal and produces a cooled object in the shape of that cavity. Molds can be simple. The forms used to create ingots of metal are like loaf pans, with the metal simply poured inside and left to cool. Most molds are for more complex shapes and are based on a pattern. The pattern imprinted into a split mold. Half of the pattern is imprinted on one side of the mold and half on the other, and then the halves are clamped together before the mold is filled. By making the mold in two parts, the pattern can be withdrawn before filling. These molds can be made with a horizontal split

Cope and drag

In horizontal molding, the top half of the mold is called the cope, and the bottom half is called the drag.

Swing and ram

In vertical molding, the leading half of the mold is called the swing, and the back half is called the ram.

Molding cores

If a mold is supposed to have internal spaces or holes, a core is often made. These cores are shaped like the internal space. The cores are usually held in place by extending past the casting and being held in place through core prints, which suspends the core like a bridge between two banks. The empty spaces around the core will fill with metal, and the core will be removed from the final casting, leaving a hole where it once was. If the core is very long, it might be supported by chaplets to prop it up. These are usually made of the same metal as the final casting as they sit in the space that will flood with material and become part of the final casting.

Dimensional tolerance

One of the important factors in choosing a casting method is dimensional tolerance. Dimensional tolerance is the variation acceptable in the size of the final product. Metal shrinks when cooling, and the type of casting influences by how much. If a product needs to be precise, a client may want a casting method that produces near net casting. This means that the product is very close to being the right size when it is shaken out of the mold.

Surface finishing

Another consideration is surface finishing. How granular, bumpy, or rough can the surface of the casting be? What is acceptable for a cast iron pan is not acceptable for a wedding ring. Very smooth metal surfaces are usually created with machining, which is an extra cost: if shiny and smooth is a desired outcome, choosing a casting method with a finer finish may reduce machining costs.

The first stage of injection moulding is to create the mould itself. Most moulds are made from metal, usually aluminium or steel, and precision machined to match the features of the product they are to produce.

Once the mould has been created by the mould-maker, the material for the part is fed into a heated barrel and mixed using a helical shaped screw. Heating bands melt the material in the barrel and the molten metal or molten plastic material is then fed into the mould cavity where it cools and hardens, matching the shape of the mould. The cooling time can be reduced through the use of cooling lines that circulate water or oil from an external temperature controller. Mould tools are mounted on plate moulds (or ‘platens’), which open once the material has solidified so that ejector pins can eject the part from the mould.

Separate materials can be combined in one part in a type of injection moulding called a two-shot mould. This technique can be used to add a soft touch to plastic products, add colours to a part or produce items with different performance characteristics.

Moulds can be made of single or multiple cavities. Multiple cavity moulds can have identical parts in each cavity or can be unique to create parts of different geometries. Aluminium moulds are not best suited to high volume production or parts with narrow dimensional tolerances since they have inferior mechanical properties and can be prone to wear, deformation and damage due to the injection and clamping forces. While steel moulds are more durable they are also more expensive than aluminium moulds.

The injection moulding process requires careful design, including the shape and features of the part, the materials for the part and the mould and the properties of the moulding machine. As a result, there are various considerations that need to be taken into account when injection moulding.

Injection moulding is used to make a range of widely used products, including common plastic items like bottle tops as well as remote control casings, syringes and more. It is also commonly used for manufacturing larger items such as car body panels.

Injection moulding is mainly used where there is a need to manufacture many thousands or millions of identical parts from a mould.

The main advantage of injection moulding is being able to scale up production to produce a large number of parts. Once the initial costs of the design and the moulds have been covered, the price of manufacturing is very low. The cost of production drops as more parts are produced.

Injection moulding also produces minimal wastage when compared to traditional manufacturing processes like CNC machining, which cuts away excess materials. Despite this, injection moulding does produce some waste, mainly from the sprue, the runners, the gate locations, and any overflow material that leaks out of the part cavity (also called ‘flash’).

The final advantage of injection moulding is that it allows for the production of many identical parts, which allows for part reliability and consistency in high volume production.

While injection moulding has its advantages, there are also a number of disadvantages with the process.

Up-front costs can be high for injection moulding, particularly with regard to tooling. Before you can produce any parts, a prototype part needs to be created. Once this has been completed, a prototype mould tool needs to be created and tested. This all takes time and money to complete and can be a costly process.

Injection moulding is also not ideal for producing large parts as a single piece. This is because of the size limitations of injection mould machines and the mould tools. Items that are too large for an injection moulding machine’s capability need to be created as multiple parts and joined together later.

The final disadvantage is that large undercuts require experienced design to avoid and can add even more expense to your project.

Aside from the length of the sink, you should pay close attention to the depth of the basins as well as the width from front to back. Someone who prefers to hand wash their dishes may appreciate a deeper sink for soaking, or a wider sink which provides a bit more room to work.

If you're planning to jump from a shallow sink to something with a deeper basin, take some measurements from the existing plumbing. If the basin hangs too low, the sink will not drain properly and modifications may need to be made behind the wall, e.g. lowering the pipe that feeds into the wall. To know how much deeper you can go without modification, measure the length of the pipe that connects the sink drain to the tee below the sink. This pipe is referred to as the tailpiece. If the tailpiece is 2" in length, then you should be able to install a new sink that is 2" deeper than what you currently have with no issues.

The kitchen sink plays a vital role in the modern-day kitchen; it’s so important that you’d struggle to live in a kitchen without a proper sink.

From cleaning large pots to preparing food, you need to make sure that your kitchen sink is great and absolutely perfect for your kitchen. Stainless steel kitchen sinks are popular due to their flexibility which makes it a good choice for:

• Homeowners in their kitchens

• Kitchens in restaurants or cafes

as well as whole other list of uses for a stainless steel sink.

In this post, we’ll cover the things that you need to know before purchasing a stainless steel kitchen sink.

Stainless steel kitchen sinks are a good choice for just about any kitchen thanks to its array of good qualities. You’d be hard-pressed to find a kitchen sink as timeless as stainless steel ones which also has the ability to complement kitchen designs nicely.

Stainless steel sinks are also famous for being strong and durable. With proper maintenance, stainless steel kitchens are expected to last for more than 30 years – a nod to its longevity and satisfactory performance.

Before you buy a stainless steel kitchen sink, you’ll need to consider some aspects to make your purchase worthwhile.

This includes:

• The grades of stainless steel

• It’s thickness (also referred to as its gauge)

• Insulation and coatings for the sink

• Its finish

Some other considerations include the number of sinks that you want as well as how you would like it to be mounted, although those factors are less important than the factors listed above.

It would also be helpful to understand how to maintain and take care of stainless sinks properly. Proper maintenance is essential to ensuring that your sink’s long-lastingness.

Stainless steel is usually steel that has been mixed with other elements to improve its properties. Think of stainless steel as a material that is mixed with the best of other materials to make a perfect final product.

The two most important materials to check before purchasing a sink is chromium and nickel. These two materials enhance the properties of stainless steel which make it durable and resistant to corrosion.

There are many aspects of a kitchen sink to consider, such as size, depth, dividers, and materials. Deciding whether you are looking for an over or undermount sink is best decided first, as it will simplify your decisions down the road. Your countertop material will be a key factor in this decision.

While undermount sinks are currently preferred for looks, overmount can be a better investment in longevity for certain countertop materials like wood. Undermount sinks, currently loved for their smooth look and how they complement stone and solid surface countertops, also get an extra inch or so of depth out of their lower mounting point.

UNDERMOUNT SINKS

Undermount sinks have that name because they sit under the counter, so that the the edge of the sink is below the level of the countertop. There are three types of undermount sink installation.

1. Positive reveal- counter stops before the edge of the sink creating a ledge

2. Negative reveal- counter overhangs the sink a little

3. Flush- counter and sink edges are aligned

Undermount sinks have their advantages and drawbacks. Examine the pros and cons to decide if one is right for your kitchen.

Pros:

• ~ Creates attractive, clean lines in your kitchen

• ~ Gives you slightly more counter space

• ~ Easy to wipe food and liquid messes directly into the sink

• ~ Undermount sinks can be deeper for cleaning large pots and pans

Cons:

• ~ Usually more expensive

• ~ Professional installation recommended

• ~ Risk of chipping the counter edge when moving heavy dishes

• ~ Water can get into gap between the sink and the counter, if not perfectly sealed. Top craftsmanship is advised.

• ~ Best used with waterproof, non-porous countertops like granite and other types of stone, or a water-resistant composite.

Undermount sinks are not appropriate for counters that are not water-tight, such as wood. Solid surface countertops are recommended for undermount sinks, since some countertop materials may not be strong enough to support the weight of the undermount sink. Talk to your contractor to be sure that the materials and sealing techniques that they use are suitable for an undermount sink.

Decisions when undergoing a kitchen renovation or producing your own kitchen – each time you make one you are faced with two more, as if you’re Hercules cutting off the many heads of the menacing Hydra. Unfortunately, we’re not here to provide you an encyclopedia that will inform your conclusions for each and every decision that you will have to make in this overbearing task, but this latest blog instalment by QN Designs will bring you the insight to hopefully make one of those decisions just that little bit easier. Here’s all that you need to know about making the choice between style and convenience, between trend and budget: the choice between having an undermount or a top-mount sink.

Typically, when you buy a sink you will find that you have the inset bowl as well as a lip lining the edge or outline. For top-mount sinks, if you drop them into a cutout hole within a benchtop, the lip will save the sink from falling straight through and clanging onto the ground. Hence, top-mount sinks are also commonly referred to as drop-in sinks. You may also hear them being called overmount sinks and rimmed sinks for the similar reasons.

While a top-mount sink sits jovially above the benchtop, an undermount sink is holding on for dear life underneath the countertop. Due to these circumstances, an undermount sink must be specially installed through methods including sandwiching the sink lip between the underside of the benchtop and a support board, bonding the sink to the benchtop using a glue-like epoxy or merely bolting the sink underneath the counter. It altogether allows for a comparatively more streamlined look on the surface where there is no visible lip but instead sports a smooth benchtop surface across the whole space. If you want to stay up to date in terms of kitchen fashion and trends, then undermount sinks are generally considered to be more marketable and in style than your traditional drop-in sinks whom have been around for eras.

When considering the price of these two sinks, you must be sure to take into account both the cost of supply and the cost of installation. For the aspect of supply, an undermount sink is going to be more expensive than an overmount sink of the same shape and material.

In terms of installation, undermount sinks are also pricier in comparison and this is quite evident when we consider all the work needed to keep these bodies from losing its stick and falling to the floor while smashing all the plates within. It includes the price of extra materials needed for the job as well as the price of external labor if you are having a third party do the work. In addition, undermount sinks are strongly recommended to be partnered with a sturdy benchtop such as engineered stone, meaning that there is also polishing to be done on the inside edges of the cut out to smooth out any coarse surfaces.

If you have an older home, it probably came with a double-bowl kitchen sink. This trend made its rounds at a time when dishwashers were not yet standard in the average American home. The primary purpose of double-bowl sinks was to make dishwashing easier: one bowl for soapy water, the other bowl with clean water for rinsing.

Nowadays, the double-bowl sink is rarely used for dishwashing. However, this type of kitchen sink does more than make dishwashing easier. Some of the benefits of a double-bowl sink are:

• It’s ideal for washing large pans and other items that you don’t want to run through the dishwasher.

• It helps keep things organized. For instance, you can put dirty dishes in one bowl while you use the other for food preparation.

• It makes garbage disposal easier too. You can use the garbage disposal on one side even if the other bowl is full of water or dirty dishes.

Today, single-bowl sinks are dominating the home kitchen designs arena. Single-bowl sinks have one deep basin without any divider. They offer a number of benefits, including:

• They provide more space for washing bigger kitchen items.

• They do not take as much counter space as double-bowl sinks.

• They are ideal for smaller kitchens.

•
