Quality and use requirements, production batch size, etc. to choose from.

    For molds that require high appearance quality, long life, and mass production, the cavity needs to choose high-grade imported steel with high mirror polishing performance, such as 718/NAK8, etc.; the core can choose medium and low-grade imported steel, such as 618/738, etc.

    The appearance quality requirements are general, and the cavity of the long-life and mass-produced mold needs to choose low-grade imported P20 steel; the core can choose low-grade imported P20 steel.
