Cemented Tungsten Carbide Hard Alloy Screw Cold Heading Dies Mian
Dies Forming Dies Mould
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.
