Forging die refers to a die which shape up the workpiece by applying a certain pressure to the closed upper and lower dies. The shaped workpiece by forging die has better organization and mechanical properties. Tungsten carbide forging die, is the forging die which made of tungsten carbide, or part of which made of tungsten carbide, tungsten carbide material itself has high wear resistance, pressure and corrosion resistance characteristics, so that the die has a very long service life and wide applicability. The types of tungsten carbide forging die can be divided into closed forging die, hammer forging die, upset forging die and roll die according to the different manufacturing equipment used.
Closed forging die: For open die forging equipment. Generally, open forging pre - forged blank is used. And then the final shape in the closed forging die. Suitable for forging small items and small and medium batch production.
Hammer forging die：Used in the hammer forging equipment, under the dynamic action of the forging equipment, the blank is forced to plastic flow forming in the forging die boring, so as to obtain higher quality forgings than open die forging;
Mechanical press forging die：For forming billets into die forgings or their semi-finished products on a mechanical press.
Upset forging die: For forming a blank into a die forging or its semi-finished product on a horizontal forging machine.
Roll forging: A fan-shaped die for longitudinal rolling of billets on a roll forging machine.
