The working principle of an injection molding machine is to inject molten resin into an injection mold under high temperature and pressure, filling the mold cavity (the shape of the mold cavity is the desired injection part). After cooling and solidification, the desired injection molded part (product) is obtained.
Injection molding is a cyclical process. Each cycle mainly includes: metered feeding-melting and plasticizing-pressure injection-mold filling and cooling-mold opening and part removal. After the plastic part is removed, the mold is closed again, and the next cycle begins. Injection molding machine operation includes three aspects: control keyboard operation, electrical control system operation, and hydraulic system operation. This involves selecting injection process actions, feeding actions, injection pressure, injection speed, ejection type, monitoring the temperature of each section of the barrel, and adjusting the injection pressure.
