It has good matching of mechanical properties such as tensile strength, yield strength, section shrinkage, elongation, impact toughness and hardness within the range of the use temperature of the Crate Mould (room temperature to high working temperature). 1. Tensile strength and yield strength Different types of crate mould have a particular emphasis on the specific mechanical properties required for forging plastic crate mould materials. At the same time, the mechanical properties at room temperature should not be considered only while the more important performance indexes at actual working temperature should not be ignored. Do not pursue a comprehensive and high target that is blindly divorced from reality. 2. Impact toughness, section shrinkage and elongation Since the choice of impact toughness index of forging crate mould material is closely related to the forging load property, if the impact toughness of forging crate mould material is low, the crate mould may crack and be scrapped for impact load equipment such as forging hammer and screw press. Under such conditions, forging crate die materials with high impact toughness should be selected. 3. Hardness In view of the fact that the hardness is closely related to the wear resistance of the crate mould in addition to the corresponding relationship with the strength index, the hardness (or wear resistance) should be improved as much as possible under the allowable conditions of impact toughness, section shrinkage rate, elongation rate and other indexes. Hardness and red hardness of forging die are important properties of forging die materials. The shape and size of crate die should be kept unchanged when working at high temperature.
