Yong Wei steel mold (Dongguan) Co., Ltd., Dongguan HPM38, HPM38 provided by Yong Wei steel mold (Dongguan) Limited. We are a steel mold, Dongguan City, An Yongwei shop (www.dgyongwei.com) located at: Dongguan specializes in: Automation mold steel, DC53, SKD11.SUS440C, SUS420 production equipment, is the target abrasive production enterprises in their efforts to achieve, from equipment manufacturing and design unit learned that the main abrasive production enterprises, especially resin abrasive production companies are on the production line automation of all or part of the transformation. Abrasives industry-wide production capacity has become the scale, but the specific production capacity of more decentralized, small-scale enterprises, economies of scale difference. Scale structure of the enterprise is still quite reasonable, low industrial concentration, still accounts for a large proportion of small businesses. Low competitiveness of enterprises and products in Dongguan HPM38, seriously affecting enhance the economic strength, especially not conducive to environmental protection and upgrading technology. Hot red hardness at high temperature working die HPM38 steel, required to maintain its organization and stable performance HPM38, 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.
