1 Material of the stamping mold

The materials for making stamping mold are steel, carbide , steel carbide, zinc alloy, low melting point alloy, aluminum bronze, polymer materials and so on. At present, most of the materials for manufacturing stamping mold are mainly steel, commonly used mold working parts materials are: carbon tool steel, low alloy tool steel, high carbon and high chromium or medium chromium tool steel, carbon alloy steel, high speed steel, matrix steel ,carbide and so on.

2. Selection principles of stamping mold materials

In the materials used in the stamping mold, can be a variety of metal materials can also be a variety of non-metallic materials, these two types of materials mainly include carbon steel, alloy steel, cast iron, cast steel, carbide, low melting point alloy, zinc-based alloy, aluminum bronze, synthetic resin, polyurethane rubber, plastic, laminated birch board, etc.

The materials used for the manufacture of the mold are also very strict requirements. Not only requires the hardness, strength and wear resistance of the material to be very high, but also to have the appropriate toughness, and the quenching property is also very high, and the heat treatment is not deformation and quenching is not easy to crack and other properties.

In order to ensure the service life of the mold, it is necessary to select the mold materials reasonably and implement the heat treatment process correctly. The selection of the correct steel type and heat treatment process should correspond to the different uses of the mold, in addition, it should also be based according to its working state, stress conditions, the performance of the processed materials, production batch and productivity and other comprehensive factors, and should focus on the above requirements of the performance.
