stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die).
Regarding the issue of stamping die materials, the materials used in stamping dies belong to cold work die steels, which are the most widely used, widely used die steels. The main performance requirements are strength, toughness and wear resistance.
In the stamping die, various metal materials and non-metal materials are used, mainly carbon steel, alloy steel, cast iron, cast steel, cemented carbide, low melting point alloy, zinc-based alloy, aluminum bronze, synthetic resin, polyurethane Rubber, plastic, laminated birch board, etc.
The material used to make the mold requires high hardness, high strength, high wear resistance, appropriate toughness, high hardenability, no deformation (or less deformation) after heat treatment, and resistance to cracking during quenching.
