The development trend of metal stamping die technology

The development trend of metal stamping die technology a. High-speed milling processing 　　 The high-speed milling processing developed in foreign countries in recent years has greatly improved the processing efficiency and can obtain extremely high surface finish. In addition, high-hardness modules can also be processed, and it also has the advantages of low temperature rise and small thermal deformation. The development of high-speed milling processing technology has injected new vitality into the manufacture of large-scale cavity molds in the automotive and home appliance industries. At present, it has developed in the direction of higher agility, intelligence and integration. b. Mold scanning and digitization system 　　 High-speed scanner and mold scanning system provide many functions from model or physical scanning to processing the desired model, which greatly shortens the mold development and manufacturing cycle. Some fast scanning systems can be quickly installed on existing CNC milling machines and machining centers to achieve rapid data collection, automatically generate various CNC system processing programs, and different formats of CAD data for reverse engineering of mold manufacturing. The mold scanning system has been successfully applied in industries such as automobiles, motorcycles, and home appliances. c. High-quality materials and advanced surface treatment technology 　　 It is very necessary to select high-quality steel and apply corresponding surface treatment technology to increase the life of the mold. Whether the mold heat treatment and surface treatment can give full play to the key aspects of the material performance of the mold steel. The development direction of mold heat treatment is to use vacuum heat treatment. In addition to perfecting the mold surface treatment, advanced vapor deposition (TiN, TiC, etc.), plasma spraying and other technologies should be developed. Improve mold standardization 　　 my country's mold standardization is constantly improving. It is estimated that the current coverage rate of mold standard parts in my country has reached about 30%. In developed countries abroad, it is generally about 80%. Previous post: Teach you the tricks of wiping hardware
