What are tungsten carbide punch pins?

Tungsten carbide punch pins can also be called tungsten carbide pins, or cemented carbide pins, which are a part of tungsten carbide dies. Tungsten carbide punch pins are mainly used for punching hardware parts or electronic parts, as well as other non-metal parts, belt holes, plastic holes, and so on. Generally, operators use tungsten carbide punch pins, tungsten carbide dies, and tungsten carbide bushings together.?

Classification of tungsten carbide punch pins

As a part of tungsten carbide dies, tungsten carbide punch pins are replaceable. According to different materials, shapes, and applications, tungsten carbide punch pins can be divided into SKD punch, SKH punch, ASP punch, guide punch, ejector punch, hexagonal punch, oval needle punch, forming punch, special-shaped punch, high-speed steel punch, and high-quality carbide punch.

Things should be paid attention to

The tungsten carbide punch pins have high hardness as well as high brittleness so workers should be very careful when using, installing, and moving them. These are the things you should pay attention to:

1. Tungsten carbide punch pins should be installed in place and fixed firmly;

2. The punching pressure of the tungsten carbide punch pins should be appropriate. And it should not be adjusted too large to avoid damaging the tungsten carbide punch pins due to excessive pressure;

3. The punching stroke should be set reasonably, and the short punching stroke will not only easily damage the material, but also increase the waste, and will directly damage the punching needle;

4. Don’t throw or beat the tungsten carbide punch pins when packing, installing, disassembly, or using the tungsten carbide punch pins to prevent the punch pins from collapsing, or being damaged.
