China abrasives industry in innovation has always existed shackles, or whether there are internal institutional reasons. Guangdong has a proven track record in business there are many, the whole of Guangdong abrasives industry to show a contending, thriving situation. Dare's business philosophy, always encourage the growth of enterprises in Guangdong abrasives. Guangdong enterprises of practical experience and business acumen makes them very flexible in its operation mode, no longer limited to simple product production and development, many companies are in accordance with the characteristics of the market and the core strengths of their business has to operate, which makes companies the operations easier on a lot higher profits. Hot red hardness at high temperature working die HPM38 material, required to maintain the stability of its organization and performance of Hitachi HPM38, thereby maintaining a sufficiently high hardness HPM38 rod, this performance is called red hardness. Carbon tool steel, low alloy tool steel is usually able to maintain this performance HPM38 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.
