The material for manufacturing Automotive mould needs to choose high-quality alloy tool steel with high mechanical properties and low thermal creep

  In order to maintain the processing accuracy of Automotive mold under injection pressure and clamping force, the feasibility of grinding and polishing the cavity parts must be considered when designing the mold structure. The injection mold cavity and core processing meet the requirements of high processing accuracy, and the shrinkage rate is consistent with expectations. However, due to the deviation of the center during molding, it is difficult for the inner and outer dimensions of the molded product to meet the design requirements of the plastic part. The guide pins and guide sleeves commonly used in the mold are set to maintain the dimensional accuracy of the front and back mold cavities on the parting surface.

  In addition, the materials used to manufacture Automotive molds need to select high-quality alloy tool steels with high mechanical properties and low thermal creep. The mold material for making the cavity and runner should be made of materials with high hardness, good wear resistance, strong corrosion-resistance, and thermal deformation after strict heat treatment. At the same time, the difficulty and economy of machining and electrical machining must be considered. In order to prevent the plastic injection mold from changing the dimensional accuracy due to aging, the tempering or low-temperature treatment of the remaining structure of the mold material heat treatment should be reduced.

  It is suitable for the vulnerable parts of Automotive mold, especially the vulnerable parts such as mold cavity and core. The possibility of repair should be considered during design to maintain the high precision of Automotive mold after repair.
