Since the molding temperature between 200--350 ℃, if the flow of the plastic is bad, the forming speed fast, the surface temperature of the molding causes the mold part in a very soon overtake 400 ℃. To ensure the accuracy and deformation tiny mold, mold steel should have a higher heat resistance when in use. 2) sufficient abrasion resistance with the expansion of the use of plastic, the plastic is often required to add an inorganic material such as glass fiber reinforced plastic or the like to, due to the addition of additives, the plastic flow is greatly reduced, leading to wear of only die therefore requires chess has good wear resistance. 3) excellent machinability most plastic mold, in addition to the need to make certain EDM machining and repair fitter. To extend the life of cutting tools, in the cutting process of work hardening is small. To prevent mold deformation affecting accuracy, hoping processing residual stress can be controlled at a minimum. 4) part shape good thermal stability of plastic injection mold is often more complex and difficult process after quenching, it should try to use materials with good thermal stability.
