Precision
Carbide is one of the hardest materials in existence. This makes it an ideal material to use for precision wear parts, like punches. This durability translates into a longer lifespan for the punch, meaning less frequent replacements and fewer interruptions to production.
Unlike regular metal, which is prone to dimensional fluctuations as it wears, tungsten carbide has high resilience and can hold its shape over time. This means that carbide punches can deliver more precise cuts while maintaining their original dimensions. In fact, they can hold their shape for up to 10 times longer than standard punches.
When it comes to precision, tungsten carbide is the best choice. It can be made with a variety of shapes, sizes and other specifications to meet the needs of any application. Additionally, tungsten carbide can be used in any machining process, making it the perfect material for precision dies and stamping tools.

Durability
Carbide punches are extremely durable, and they withstand high-pressure applications without deforming or breaking. This durability minimizes downtime and carbide punches custom reduces maintenance costs. It also improves productivity, because a durable tool can be used for longer periods of time. In addition, tungsten carbide has excellent wear resistance, which extends the lifespan of the punch and eliminates the need for frequent replacements.
Tungsten carbide is a hard metal material that can withstand high pressure and heat without damaging the tool or losing its shape. It is a good choice for use in applications that require a high level of precision. Compared to steel, it can hold its sharp edge for a longer period of time and can withstand the high temperatures and vibrations associated with cutting, shearing, and stamping.

Heat Resistance
Carbide punches are made of a hard metal that is very tough and durable. This makes them ideal for use in cutting and stamping applications. Carbide punches are also available in different grades, allowing you to choose the one that is best for your specific application. Tungsten carbide is a popular material for making punches, as it is known for its strength and durability. It also has the advantage of being able to resist heat and corrosion.
Tungsten carbide punches are typically manufactured using a CNC machine or an EDM. This allows them to be produced with the desired dimensions and shape. The machining process may require some special tools, such as a profile grinding machine or a plain surface grinder with diamond grinding wheels.
During production, it is important to consider the factors that influence the lifespan of the punch. These include design structure, selection of materials, machining, and heat treatment. Improving the tungsten carbide punch life can delay the failure of the die, saving money and time.
Tungsten carbide is robust against compressive stress, but it is weak against tensile stress. It is important to ensure that the punch holding section is reinforced against tensile stresses, especially if the punch will be subjected to high-speed impact. It is also important to consider the temperature of the part during forming.
Ease of Maintenance
Tungsten carbide is one of the hardest materials in the world, more than twice as hard as steel. This rigidity and unparalleled strength translate to a long lifespan for punches, minimizing downtime and the need for replacements.
However, tungsten carbide is difficult to machine. It requires expensive machining equipment to grind and shape it into the desired punch configuration. This includes profile grinding with diamond wheels, surface grinding, and wire-cut EDM machines.
To maximize punch life, consider using a TiCN coating for your carbide dies. This high-quality coating is engineered to withstand the extreme temperatures carbide punches of metal stamping. While more expensive than a general-purpose coating, it will last longer and minimize wear on your punches.
Another way to increase punch life is by utilizing a solid punch. Ejector punches are helpful for minimizing slug pulling, but they can be more prone to damage. If you’re stamping HSLA materials, consider using a solid punch with slug-retaining dies instead.
Lastly, a good toolmaker will recommend adding shears and back tapers to your punches. While these alterations will add to the upfront cost of your punches, they’ll save you time and money in the long run by reducing tool maintenance and press downtime.
