Injection molds are important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application of plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the requirements for molds are getting higher and higher, traditional mold design method can not meet present requirements. Compared with the traditional mold design, computer-aided engineering (CAE) technology not only can reduce the cost and the labor intensity,but also can improve productivity and ensure product quality.
Injection molds are a tool for producing plastic products; they are also tools that give plastic products complete structure and precise dimensions. Injection molding is a processing method used in mass production of complex parts of certain shapes. Specifically, the plastic melted by the heat is injected into the cavity by the high pressure of the injection molding machine, and after cooling and solidifying, the molded article is obtained.
