State launched a series of new industry development planning and measures to encourage and support a number of projects related to our industry, providing a good opportunity for the development of our industry. We must thoroughly study and use of the government introduced a series of policies to encourage the development of Dongguan HPM38, plans to seek a good development of our industry. New Materials "Twelfth Five Year Plan" developed six areas of focus catalog HPM38, which involves abrasives are: ①, semiconductor materials HPM38 material, and actively develop new semiconductor materials such as silicon carbide, promote efficient, low-cost photovoltaic materials industrialization; ②, the positive development of large size silicon nitride ceramics, sintered silicon carbide ceramics; ③, to further improve the special ceramic matrix and silicon carbide, silicon nitride, aluminum oxide and other reinforcing fibers and the like. Related business enterprises should focus on joint research and development of new materials and new products. Hot red hardness at high temperature working die, required to maintain its organization and stable performance HPM38 wholesalers, thereby maintaining a sufficiently high hardness, this performance is called red hardness. Carbon tool steel, low alloy tool steel is usually able to maintain this performance in the temperature range 180 ~ 250 ℃, the chromium-molybdenum hot work die steel is generally in the temperature range of 550 ~ 600 ℃ to maintain this performance. Red hardness of steel depends on the chemical composition and heat treatment of steel. Mold heat treatment is important to ensure mold process performance. It follows the performance of the mold has a direct impact. Manufacture of precision molds: organizational change is uneven, not completely formed and heat treatment of residual stress caused by excessive mold deformation after heat treatment processing, assembly and mold used in the process, thereby reducing the accuracy of the mold, or even scrapped. The strength of the mold: the development of improper heat treatment process, heat treatment operations are not standardized or heat treatment equipment status is not intact, resulting in being mold strength (hardness) less than the design requirements for processing.
