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.
