Mold working life: the organizational structure of heat caused by unreasonable, excessive grain size, leading to major properties such as mold toughness, thermal fatigue performance, wear resistance, etc. decline, affecting the working life of the mold. The manufacturing cost of the mold: a middle part of the mold cracking or final step of the manufacturing process, heat treatment caused the deformation tolerance and tolerance performance in most cases will die scrap, even if the repair can still be used, an increase in time will , to extend the delivery time, improve the manufacturing cost of the mold. It is the quality of heat treatment technology and mold have a very close relationship, making it two kinds of technology in the process of modernization, promote each other and improve together. Since the 1980s, the international mold heat treatment technology developed rapidly in the field of vacuum heat treatment technology, the mold surface strengthening technology and pre-hardened mold material technology.
