70 years since the last century began, the international community put forward the idea of pre-hardened, but because of machine tool and cutting tool rigidity constraints, pre-hardened mold hardness can not be used to achieve hardness, so the pre-hardened technology, R & D investment is not. As the machine tool and cutting tools enhance the performance of the pre-hardened mold material accelerated technology development, to the last century 80's, the international timber industry developed countries in the plastic mold using the ratio of pre-hardened module has reached 30% (currently 60% above).
China in the pre-hardened mold material technology, started late, small-scale, we can not meet the domestic mold manufacturing requirements. Use of pre-hardened mold material, mold manufacturing process can simplify and shorten the manufacturing cycle of molds, improve the manufacture of precision molds. It can be predicted, with the advances in processing technology, pre-hardened mold material will be used for more types of mold.
