Because all kinds of stamping die working conditions are different, the
press die components material requirements are also different.
Requirements for blanking die materials. For the thin plate, the working parts of the blanking die are required to have high wear resistance and hardness. For the thick plate, punching die not only requires a high abrasion resistance and compressive yield point, in order to prevent the mold fracture or collapse, but also should have high fracture resistance and high flexural strength and toughness.
Requirements for stretching die materials. It is required that the
mold parts material has good anti adhesion property, high wear resistance and hardness, strong toughness and good machining performance, and the deformation of the heat treatment should be small.
Cold extrusion die material requirements. Requires press die components have high strength and hardness, high wear resistance. In order to avoid the impact fracture of breaking, but also requires a certain toughness. Because of the large temperature rise in the extrusion, it should also have a certain heat resistance and heat resistance.
