Cemented Carbide Punching Dies

Tungsten Carbide Cold Heading Dies Introduction:

In standard parts industry, tungsten carbide punching dies need to under great unit pressure in cold upsetting deformation process . At the same time the metal flow intense, thus requiring tungsten carbide punching dies have high strength, good fatigue resistance, high hardness and good fatigue resistance, in order to ensure the punching die under high pressure without breaking, deformation and wear resistance. Tungsten carbide punching die raw material is produced by powder metallurgy composite materials, which have high hardness, wear resistance,life is several times and several hundred times than ordinary cold heading die.

With carbide manufacturing standard tungsten carbide punching die, not only have high dimensional accuracy of parts, but also greatly improve the life of the cold heading die, can create good economic and social benefits.

1.High wear resistance. Tungsten carbide cold heading dies material high wear resistance, tensile modulus can be guaranteed, long-term work in any degree of deformation, ensuring standard size unchanged.

2.Excellent in polishing. Carbide has a good polishing, can be processed into the die hole mirror light, ensuring high quality standard surface.

3.Adhesion to metal is small. In the tungsten carbide cold heading process, ferrous metal material adhesion small carbide tooling materials, ensuring a high tungsten carbide cold heading die life.

4.The friction coefficient and energy consumption is small.

5.High thermal conductivity. Since the thermal conductivity of the tungsten carbide die is high, heat generated during the cold forging can quickly conducted away to improve the durability of the mold.

6.Good corrosion resistance.
 

1.All raw materials are tested in terms of density, hardness and TRS before use
2.Every piece of product goes through in-process and final inspection
3.Every batch of product can be traced
