Die general for mold components product appearance quality requirements, the forming parts material selection are as follows: a) small, precision mould cavity and core are made of imported P20 or P20+Ni steel grade. B) of large and medium-sized mold, the molding of plastic has no special requirements for steel, the cavity can be used in cheap imported P20 or P20+Ni steel; core can use low-grade imported P20 steel or imported high quality carbon steel S50C, S55C, also can choose the domestic plastic mold steel. C) for cavity erosion dermatoglyphic pattern, when the eclipse pear should strive to avoid using P20+Ni class 2738 (738). .7 for no appearance quality requirements of the internal structure, molding material has no special requirements for steel, its forming parts material selection are as follows: a) for large and medium-sized mold, imported P20 or P20+Ni steel cavity can choose cheap, can also be imported high quality carbon steel S55C, S50C or domestic P20 or P20+Ni the plastic mould steel
