Carbide heading dies

In standard parts industry, tungsten carbide cold heading dies need 
to under great unit pressure in cold upsetting deformation process , 
when a large degree of deformation and material hardness, units of 
pressure up to 2000MPa more. 

At the same time the metal flow intense, thus requiring tungsten 
carbide cold heading dies have high strength, high hardness

and good fatigue resistance, in order to ensure the cold heading

dies under high pressure without breaking, deformation and wear 
resistance.Tungsten carbide cold heading 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 cold heading 
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.
