Material Selection Of Plastic Mould
- Jun 13, 2017 -

1, the working conditions of plastic mold: Due to the development of plastic and plastic molding industry, the quality of plastic mold requirements are increasingly high, so the failure of plastic mold and its impact factors have become an important research topic. The main working parts of plastic mould are forming parts, such as convex die, concave die and so on, they form the cavity of plastic mold, and the various surfaces of plastic workpiece are formed and contact with plastic directly, which is subjected to pressure, temperature, friction and corrosion. 2, plastic mold material Failure reason analysis: General mold manufacturing including mold design, selection of materials, heat treatment, mechanical processing, commissioning and installation process. According to the investigation, it is shown that the material and heat treatment of die are the main factors that influence the service life of die. From the point of view of total quality management, the factors which affect the life of die can not be measured as polynomial, but should be the product of many factors, so the quality of mould material and heat treatment is very important in the whole mould manufacturing process. 3, plastic mold steel performance requirements with the rapid development of manufacturing, plastic mold is an indispensable tool in plastic molding and processing, the proportion of total mold production increased year by day, with the development of high-performance plastics and continuous production, plastic products are growing, the use of continuous expansion of products to precision, large-scale, complex development. Molding production to high-speed development, the working conditions of the mold more complex.
