  According to the investigation, the die material and heat treatment accounts for about 70% of all the die failure factors, which are the main factors affecting the die life. Therefore, in the mold design and manufacturing process, the selection of mold materials and heat treatment process is particularly important. Stamping die materials are steel, carbide, steel bonded carbide, zinc based alloy, low melting point alloy, aluminum bronze, polymer materials, etc.. At present most of the stamping die manufacturing materials made of steel, type of die components materials commonly used are: low carbon tool steel, alloy tool steel, high carbon high chromium or chromium tool steel, carbon steel, high-speed steel, cemented carbide and matrix steel, hard alloy steel etc..

  Dalian stamping die work to withstand shock, vibration, friction, pressure and tension, bending and torsion load, and even work at higher temperatures (such as cold extrusion), complex working conditions, easy abrasion, fatigue, fracture and deformation phenomenon. Therefore, the requirements of the working parts of the mold material than ordinary parts. It is required that the working parts of the die have good adhesion resistance, high abrasion resistance and hardness, strong toughness and good machinability. In the mold of the use of more carbon tool steel T8A, T10A, etc., the advantages of good processing performance, low price. But the hardenability and the red hardness difference, the heat treatment deformation is big, the bearing capacity is low.
