The profound significance of plastic mold?

    Plastic mould materials with the increasing of plastic production andapplication, puts forward more and more requirements for plastic mould,promoted the development of plastic mold. At present, the plastic mold is moving towards high efficiency, high precision, high life direction, promoted the rapid development of materials plastic. China currently used for steelplastic mold, according to the heat treatment of steel characteristicsclassification and the use of the 3-2 table, see table 3-2 for plastic mouldsteel carburizing steel category classification of type A, MASTER plastic injection toy mould, carburizing plastic mould steel carburization plastic die steel for plastic mould cooling extrusion. In order to facilitate the cold extrusion, this kind of steel in annealing state must have plastic deformation resistance of high and low, therefore, have low or ultra low carbon content ofthe steel requirements, in order to improve the wear resistance of die, this kind of steel in cold extrusion after carburizing and quenching and temperinggenerally processing.
