Temperature control:
Barrel temperature: the injection molding process needs to control the temperature of the barrel temperature, nozzle temperature and mold temperature. The first two temperatures mainly affect the plasticization and flow of plastic, while the latter temperature mainly affects the flow and cooling of plastic.
Each kind of plastic has a different flow temperature, the same kind of plastic, due to different sources or grades, its flow temperature and decomposition temperature is different, this is due to the average molecular weight and molecular weight distribution due to the different plastic in different types of injection molding machine plasticization process is also different, and thus the choice of barrel temperature is not the same.
Injection molding machine main considerations:
Injection molding machine will be thermoplastic plastic or thermosetting plastic using plastic molding molds made of various shapes of plastic products of the main molding equipment. Divided into vertical, horizontal, all-electric type. Injection molding machine can heat the plastic, the molten plastic to apply high pressure, make it shot and filled with mold cavity.
Chinese plastics processors in the coastal areas of South and East China have shown increasing interest in robots, but the penetration rate of injection molding machine robots in the domestic plastic machine industry is less than 10%. Robots can ensure consistent running cycles, improved quality, and greater safety.
