How to choose suitable mould materials for high-speed stamping?

     The following factors need to be considered when choosing suitable mould materials for high-speed stamping:

    Production batch: for mass production, high quality mould steel with good abrasion resistance, such as Cr12MoV, SKD11 and other alloy steels, should be selected to improve the life of the mould12.
    The performance of the material being stamped: when stamping hard materials or materials with large deformation resistance, it is necessary to choose materials with good abrasion resistance and high strength, such as cemented carbide, which has good abrasion resistance and corrosion resistance.

    Material Characteristics: Commonly used materials for high-speed stamping moulds include high-speed steel, alloy steel, cemented carbide and so on. High-speed steel has high hardness, high wear resistance and good red hardness; alloy steel has high hardness and good toughness; cemented carbide has extremely high hardness, but is more costly and difficult to process.

    Heat treatment process: choose a suitable heat treatment process according to the use requirements of the mould, in order to improve the use temperature, hardenability and red hardness of the mould, and avoid tempering brittleness and volume expansion.
