Hot melt resin-bad composite material molding process is a kind of composite material processing technology which melts the raw material resin at high temperature and injects molding. Advantages of hot-melt resin-bad composite material molding process: 1. Injection molding is fast, with high molding efficiency and simple operation; 2. High molding accuracy, high precision parts can be obtained; 3. The mold debugging and replacement is fast; 4. After the mold replacement, the parts can be the same as the original parts, which is
conducive to mass production; 5. The product has beautiful shape and smooth surface, and the molding quality is stable. The disadvantages are: 1. The material consumption is high, and the tonnage of the injection machine is relatively large; 2. Some brittle materials are easy to break in processing; 3. The temperature requirements for injection are high, which affects the automation level of the equipment.鼎湖山景区>职工食堂管理制度
