Improve Service Life of Tungsten Carbide Die

Tungsten carbide die a kind of composite material that made by powder metallurgy method. Tungsten carbide has high hardness and good wear resistance. It owns high elastic modulus and working temperature. While the service life of dies also could improved several times and even more than dozens of times. Tungsten carbide is regarded as die material, and is mainly used for drawing die, cold extrusion with little impact force and cold punching mold.

In order to improve the service life of tungsten carbide die, people should pay attention to following points:

Firstly, the selection of tungsten carbide die and hot treatment for insert should obey national standards and specifications. At the same time, people who use the tungsten carbide die had better maintain it in time and ensure that the die steel will not be rust and alloy core oxidation. Secondly, structure of tungsten carbide die must be reasonable. Finally, it must be precise in the process of manufacture, and tolerances are required to control strictly.
