Pre-hardening technology

Since the 1970s, the idea of ​​pre-hardening has been proposed internationally. However, due to the rigidity of the machine tool and the constraints of the cutting tool, the hardness of the pre-hardening cannot reach the hardness of the mold, so the research and development of the pre-hardening technology is not large.

However, due to the rigidity of the machine tool and the constraints of the cutting tool, the hardness of the pre-hardening cannot reach the hardness of the mold, so the research and development of the pre-hardening technology is not large. With the improvement of the performance of machine tools and cutting tools, the development of pre-hardening technology for mold materials has accelerated. By the 1980s, the proportion of pre-hardened modules used in plastic molds in industrialized countries in the world has reached 30% (currently More than 60%).

In China, the pre-hardening technology of mold materials started late and has a small scale. At present, it cannot meet the requirements of domestic mold manufacturing. The use of pre-hardened mold materials can simplify the mold manufacturing process, shorten the manufacturing cycle of the mold, and improve the manufacturing precision of the mold. It is foreseeable that as processing technology advances, pre-hardened mold materials will be used for more mold types.
