Industrial mold field

Molds used for a long time (more than 1,000,000 times) should use high-hardness steel, with a hardness of 48-65HRC. Molds used for medium long time (100,000 to 1,000,000 times) should use pre-hardened steel with a hardness of 30-45HRC. Molds used for short periods of time (less than 100,000 times) should use mild steel with a hardness of 160-250HB.
