Tungsten carbide is one of the hardest and most wear-resistant materials available. It is often used for die components in high volume manufacturing situations. It also used for machine parts that come in contact with very abrasive materials. Tungsten carbide is a combination of tungsten carbide powder and a binder metal, such as cobalt or nickel, which holds the tungsten carbide powder together. By adjusting the percentage of binder metal, tungsten carbide components can be made very wear resistant but brittle or very durable but not as wear resistant. Very smooth, polished finishes can be produced on tungsten carbide components which improves wear resistance of the component and aids significantly in metal forming applications.

![]() Given that tungsten carbide, a metal created by bringing together carbon and tungsten, is one of the toughest, most reliable and extremely durable metals you can find, it is not surprised that there are a great deal of usages for the metal. You can find it being used at home, for sports but there are also extensive military and industrial uses for tungsten carbide, making it an extremely versatile piece of metal. The strength of tungsten carbide is one of the strongest points of the metal and another thing that it is known for is the fact that there is a melting point that is extremely high. Using the Mohs scale, which is used to test hardness, the score achieved by tungsten carbide is 9. To put this into context, the only thing that has a higher score than tungsten carbide is a diamond, which manages to score a rating of 10. As the old saying goes it takes a diamond to cut a diamond but it also takes a diamond to cut tungsten carbide. You should be able to take this information and realise that the hard quality of tungsten carbide has a great range of benefits and the metal is extremely scratch resistant. The main use of tungsten carbide is cutting Given that it is scratch resistant and so tough, it makes sense that tungsten carbide is used extensively for cutting work. For high scale and serious cutting jobs, commonly found in the construction and mining industries, drills with a tungsten carbide tip can do a great job. It is reported that around 60% of all tungsten carbide material is used as cutting devices in these industries, indicating its importance to the economy. However, once you get beyond this major use, the use of tungsten carbide becomes far more widespread and the metal pops up in a lot of places that you would probably never think of. It stands to reason that tungsten carbide can be of benefit in razor blades although some people may think that it is too powerful a metal to be used. When used safely, tungsten carbide can help to make some of the most effective and efficient razor blades known to man. However, tungsten carbide is not just used for elements where cutting has to be carried out. You may be shocked to learn that tungsten carbide plays a key role in the development of so many different pieces of jewellery. Your first thought may be that something so tough and harsh is the last thing you would want to wear to look stylish but when you think about it more deeply, there are a number of benefits that can arise from using the material in this fashion. After all, so many pieces of jewellery become tarnished, scratched and ruined but this is not going to happen to a piece of jewellery that has been made from tungsten carbide. When it takes a diamond to cut or engrave these types of jewellery, you can rest assured that it will manage to stand up to the bumps and tumbles that come along with everyday life. Tungsten Carbide can also be used as extrusion dies, and wire drawing dies in wire drawing applications. You can find tungsten carbide around the home You will also find tungsten carbide being used in a simple manner in some of the most important items you will find in a house. Without light, a home would be a gloomy place to be and the invention of light bulbs helped to brighten up many a household. While light is the main energy that people notice from a light bulb there is an awful lot of heat generated from light bulbs, which makes tungsten carbide an essential component for light bulb filaments. Given the high level of heat that tungsten carbide can withstand, this makes them an obvious choice for creating light bulbs that can be used for a considerable period of time without being overly concerned about burn out. With tungsten carbide also being used in ballpoints to make sure that the ball is aligned with the ink, it would be fair to say that tungsten carbide is an essential part of everyday life. The uses of tungsten carbide are many but it would be fair to say that the benefits of tungsten carbide are fairly obvious. Tungsten Carbide, also called cemented carbide, can be used to machined as tungsten carbide parts, and carbide bush used in a wide range of industries such as automotive, aerospace, electronics manufacturing. This is a metal that can be relied upon regardless the situation or occasion. Whether you need something to withstand pressure, put up with excessive temperatures or even impact on other tough materials, tungsten carbide is the metal that can be relied upon time and time again. This is why it is the natural choice for so many manufacturers. ![]() The punching tool is part of the typical industrial requirement and is usually manufactured by a tool-making company on a contract basis. Punching tools essentially consist of a punch, a die, and the stripper. What is a punch tool? The punching tool represents the technical basis for the separating process of punching and must meet high requirements in terms of load capacity, resistance and dimensional and shape accuracy. The punching tool is used to manufacture flat parts from various materials, for example, sheet metal. Technical basics of the punching process The punching can either be done manually or with the help of modern CNC technology. With manual punching, the sheet to be processed is first placed between the punch and the die. The punch is then guided onto the sheet metal with the aid of hydraulic or leverage with high pressure and cuts it at the interface between the punch and die. CNC punching machines also work according to this principle but carry out the individual process steps largely independently. The manufacturing process is usually divided into the types of shear cutting and wedge cutting, depending on the separation principle. During shear cutting, the pressure surface of the punching tool has a cutting edge that causes cracks to form and ultimately leads to the material tearing through. Wedge cutting, on the other hand, is characterized by two wedge-shaped cutting edges that cut through the sheet metal at a specific cutting wedge angle. Variants for punching tools Revolver punching machines use tools in which the punch sits in a sleeve that completely encloses it. It acts as a tool guide and scraper. The ram presses on the tool from above and drives the punch through the sheet metal. The plunger then moves upwards again by springs. In another variant, the tools are arranged like a matrix in several rows. In contrast to the turret plate, the tool magazine is not moved. Each magazine location has its own ram that can perform the punching process. Stamping tools are often used as progressive tools in complex stamping systems. When bending tools and cutting tools are used together, one speaks of the punching and bending process. Steel strips are unwound from a coil and fed into the hydraulic system; the punched sheets automatically go through a whole series of process steps. Sharp edges are often than ground off by tumbling. Compared to conventional punching tools, fine blanking tools are primarily characterized by the fact that they meet the highest requirements in terms of dimensional and shape accuracy. With the help of fine blanking tools, it is possible to make the cut surface of the workpiece to be machined smooth and free of tears. The associated manufacturing process is usually referred to as fine blanking or precision cutting. A typical area of application for fine blanking tools is the production of components with the highest demands on dimensional accuracy. This includes, for example, gears with modules from 0.2 to 10 mm and thin sheet metal from 1 to 10 mm. Toothed racks or similar machine elements are also manufactured using the fine blanking process due to the high demands. Often the accuracy achieved is so high that no further reworking is necessary. The structure of the fine punching tool differs from the conventional punching tool in that the tool has a special serrated ring plate. This is moved by the outer ram of the press with the upper part, while the cutting punch is actuated in a separate movement by the inner ram. The cutting process is carried out in a tensioned state. In addition to the serrated ring, the cutting gap is of particular importance in fine blanking tools. The cutting gap ensures the particularly smooth surface and is defined depending on the sheet thickness. In principle, triple-acting automatic punching machines are required to operate precision stamping tools. ![]() Dongguan JLS Precision Mold Parts Co., Ltd is a factory located in Dongguan, China.

Like all business decisions, the cost will inevitably be a factor but there is also a need to take on board the effectiveness of the product, the inconvenience of replacing worn parts every so often and the value for money of the overall process. The lowest price may be of benefit and interest to many companies but for many businesses, the lowest price is not the price that is important. It is the price that provides the most value for money that is the one that businesses have to look out for and this is where the introduction of tungsten carbide can make all the difference.
When a tool or material is being used to carry out the same function on a highly repetitive basis, it is inevitable that some wearing will occur. When the material comes into contact with another in a cutting or rubbing fashion, the effectiveness of the part doing the cutting or rubbing will eventually become lessened by the job it is being employed to do. This is an inevitable part of the manufacturing process and this is why the use of wear products needs to be factored into any project. However, while it is inevitable that some jobs and tasks will result in an element of wearing away occurring and for parts needing to be replaced, there are some substances and materials that are more reliable and can withstand a lot more work and wearing than other materials. Not many materials impact on tungsten carbide There are not many materials in the world that have the ability to scratch or cut tungsten carbide, so the wear resistance is very high. One of the few materials that can impact tungsten carbide in such a fashion is diamond abrasives which are operating an industrial level. With this in mind, it is easy to see why tungsten carbide is the natural selection for so many companies that are looking to find the best value when it comes to their wear parts. In years gone by, many firms would not be overly concerned about replacing parts as long as the finished product was up to standard. Times have changed now and every penny must be accounted for by a firm. This is why every aspect of the manufacturing process is up for consideration and a firm that can reduce the amount of waste or replacement parts that they burn through on a regular basis will find that they can positively impact their bottom line. The use of tungsten carbide may cause a rise in the purchase of materials at one point but in the long run, the switch to this style of material will provide many benefits, which is why firms should be looking to tungsten carbide for wear parts. Tungsten carbide is a substance you can rely on The benefits of tungsten carbide are well known and they are often used to great effect in the manufacturing industry. The powder itself can be utilized as a very effective abrasive substance or the powder can be turned into a cutting shape which is highly effective for the production of tools, machinery and even in the creation of jewelry. The strength and very physical nature of tungsten carbide make it a number one choice for a wide range of applications. It is a very strong material and the fact that it has a high level of resistance to wearing makes it a material that is in high demand. As stated, while there is an acceptance that the precision carbide parts are a vital part of the manufacturing industry, a wear part that is provided with tungsten carbide can provide a lot of services. It is this value for money that sees tungsten carbide hailed as one of the most important components ( such as carbide punch and hardened steel bushings) of the modern era when it comes to cutting and working.

Starting with advice via development and design through to reliable production and corresponding service, we are a provider of one-stop solutions for tungsten carbide. Cemented tungsten carbide is a sintered material mainly consisting of tungsten carbide and a binding agent. The main binder is usually cobalt. If the focus is on creating corrosion resistance, nickel or nickel/chromium is the perfect binding agent. It’s the mix that matters: The binder content and the grain size of the carbides determine the specific tungsten carbide features. A high content advances toughness, a lower binder content increases wear-resistance. The choice of grain size, in turn, affects hardness. The finer the grain, the harder the material. The coarser the grain, the higher the fracture toughness. The best composition depends on the technical requirement and the respective application. Due to long-standing experience and the broad expertise of our technicians and engineers, we are able to realize the suitable component in the precisely accurate material composition. We provide tungsten carbide wire and textile guides used in production machinery as cost-optimized standard parts.

Compared with ordinary stamping, the speed of high-speed stamping is hundreds of times to thousands of times per minute. Defining 'High Speed' High-speed stamping is a relative term. What is considered high speed varies depending on the size of the part? For an automotive fender, 100 parts per minute (PPM) would be very fast. In comparison, stamping a small, simple washer at 100 strokes per minute (spm) would be very slow. High-speed progressive stamping dies for forming very small, complex parts, such as electrical connectors, which can be designed so the parts can run at 1,200 to 1,500 SPM. High-speed stamping means compare with tradition stamping machines, their stroke operation speed much faster than normal. High-speed stamping is an operation that generates special needs due to fast operating speeds. These special requirements generally relate to stock control, slug control and excessive wear problems. Speed-related problems typically start when press speeds exceed 100 strokes per minute. High-speed stamping is one of the progressive die stampings. It has an auto-transfer feeding system. And it also special designed for lots of numbers of parts of production. From the internet videos or view stamping factory at first glance, high-speed stamping appears do not require a big force to punching or blank out parts. Components at most times are produced from thin, small and relatively soft metal sheet material. Because the component material is thin and small, It’s easy to stack up and jam in the workstation, die plate, or the matrix. If the punch lacks the necessary hardness of strength, it fails or wears at a short time. Two factors affect compressive strength: alloy content and punch material hardness. Alloy content generally speaking it is means you should choose what kind of materials. Most of the times it will affect the lifetime of the tooling. Alloy elements such as molybdenum and tungsten contribute a great deal to the compressive strength. Meanwhile, the hardness of steel also can improve the wear resistance. But the material content will limit the highest of hardness. Generally speaking, tungsten carbide punch and hardened steel bushings are more often used as die tools when stamping metal parts. Because carbide punch and carbide dies has the better hardness and wear resistance compared with steel punches or dies. When the punching load exceeds the part material tensile strength limit, the slug suddenly separates from the part. This sudden loading of pressure on the punch generates a reverse force that often leads to punch head breakage. The punch head must have good tensile strength. it was determined by the material alloy and hardness. When the punch force removed, the deformed high-speed stamping part partially restored. The dimension of the blanked component is not 100% according to the shape of stamping tooling, then it will out the range of tolerance of mold. Stamping not only generates plastic deformation, but it also generates elastic deformation. The art of high-speed stamping is a tool maker’s skill. The high-speed stamping tooling has designed a special system to release the slug out of the matrix to avoid jammed in the workstation. This is very important to get stable quality products with high-speed stamping. #carbidebushings #hardenedsteelbushings #punchanddie #carbidemoldcomponents #carbidepunch ![]() How to Run a Stamping Die at Maximum Speed with Minimal Breakage? Support Equipment Must Match Speed Before looking at the tool design for speed capability, you should first understand the speed capabilities of the press and supporting equipment that will run the die. The tool's speed capability is irrelevant if the press feeder, raw material payout, vision inspection, sensors, take-up reel, and conveyors cannot keep up. When determining the capability of some of this equipment, you need to convert a linear speed such as feet per minute (FPM) or inches per second (IPS) into strokes per minute. To calculate the maximum speed of the equipment in SPM, you must divide the linear speed by the progression. Balancing Speed and Breakage Two factors establish a stamping die's speed capability. The first is simply how fast the part can physically be produced. The second is at what speed the tooling fails (breakage). The strength of carrying features (carrier), how high the part must be lifted, and the mechanical limitations of the springs and side action cams (mandrels) physically limit how fast the part can be made. Although problems associated with these items can cause tool breakage, they do not originate from tool breakage. Design to Counter Physical Limits. In one way or another, each of the physical speed-limiting factors is dictated by the configuration, or design, of the part. When possible, it can be very helpful for you to work closely with the product designer to identify product compromises that make the part more "speed-friendly." 1. For example, a part may be currently designed with very few areas where it can be attached between progressions, making the carrier too weak to feed the parts at high speeds without collapsing. A minor design change that makes the carrier more robust than can increase speed capability. 2. Other design compromises can be made without compromising part quality. For example, if the product design can be altered to eliminate the need for or reduce the travel of side action cams, or reduce the distance that springs need to travel, valuable increases in speed can be achieved. 3. Reducing how high a part must be lifted within the progressive die can help attain higher speeds. The most common way of limiting lift is by using more forming stations. A high form can be redesigned with multiple stations using lower forms that require less lift Preventing Tool Failure Tool failure is also very challenging. The cost associated with tool breakage makes it a hot topic. Although applying commonsense practices of robust tooling design certainly is helpful, there is no substitute for experience when you are designing tooling to prevent breakage. Often, when you are stamping smaller, more intricate parts, addressing breakage is easier said than done. Not Just Thicker Parts. Designing dies to run at high speeds is not as simple as making a die component (including carbide punch, carbide bushings ) thicker in a specific area. In fact, sometimes that approach backfires, because it results in more reciprocating mass, therefore actually increase the potential for breakage. Careful analysis of the forming and blanking pressures and their effect on the tooling is critical. Using strengthening techniques, such as the strategic placement of radii and chamfers on the tooling, is more effective. Know the Breaking Point. To effectively stamp at high speeds, you must understand tool breakage and the point of diminishing returns. This is very tricky to balance. Because experience is crucial to establishing design practices that prevent breakage, you must first understand and balance between the long-term benefits of running faster and the short-term benefits of running slower. Because tool breakage is costly—downtime, design hours, and detail manufacturing—it is natural to feel compelled to reduce the speed so tooling breakage won't occur. Conversely, if breakage is carefully analyzed and redesigned, the knowledge attained can be used to improve the speed capability of future tools. It's common to hear frustrated toolmakers say, "Do you want to run the tool at 1,000 SPM all day with no problems, or do you want to run it at 1,200 SPM and have it break down every two hours?" The short-term benefit of running parts at slower, proven speeds is that you will not incur unplanned downtime and tooling costs caused by breakage. Of course, the disadvantage of running at slower speeds is that you will never learn the weak points in a tool and therefore never attain the knowledge needed to maximize the speed it can be run. If you never push the speed limit, how will you ever know what the highest attainable speed is? When All Is Said and Designed Die designers' thirst for knowledge can drive the push for higher speed limits. That having been said, stampers are in business to make a profit, and pursuing high stamping speeds at any cost is irresponsible. Working closely with the pressroom personnel to analyze breakages and improve tool designs is likely to net the best results. Whether you are stamping a large fender or a tiny electrical pin, effectively increasing the speed of your stamping tool will result in cost savings. Once you know the capability of the supporting equipment, you can begin focusing on what can be done within the tool design to increase stamping speeds. The combination of refining the product design so it is more speed-friendly and eliminating speed-related breakages are major steps in the process. It is also of utmost importance that everyone involved in the designing, building, and running of the stamping dies is on the same page. Each individual must understand where the company stands on the balance between short-term breakage costs and the long-term benefits of pursuing higher speeds. If anyone within the chain is pressured by others in the group to either run the tool too fast or slow, he or she ultimately will likely take the path of least resistance, whether or not it is in the company's best interests. #tungstencarbidedies #carbidedies #punchanddie #tungstencarbidedies |
