The function of the barrel heating system is to maintain the raw material temperature

The heating stage of the initial start-up of the injection molding machine and the high temperature performance plastics have a greater demand for heat and consume more electricity. "The heating system of the material barrel has been applied ten years ago. At present, the energy-saving technology of the heating system of the material barrel has been relatively perfect," Cai Hengzhi said.
"In addition to the energy-saving heating coil power system and the barrel heating system, the mold cooling and heating system is also widely used in the energy saving of injection molding machines. Because the mold cooling and heating system is very important for the production of high-precision and high-quality plastic parts, such as light guide materials and some transparent materials with fast cooling and fast heating. The three energy-saving systems of injection molding machines have been fully applied," Cai Hengzhi said.
"Intelligent manufacturing and lean production are also reflected in the energy saving of injection molding machines. For example, the application of robots improves the production efficiency, thus shortening the production cycle, and plays a great role in the energy saving of injection molding machines from the side." Cai Hengzhi added.
Energy-saving heating coil all-electric and oil-electric hybrid injection molding machine is the leading direction
The early injection molding machines of energy-saving heating coils were all hydraulic. Due to the need of environmental protection and energy conservation, as well as the mature application of servo motors and the sharp decline in price, there are more and more precision injection molding machines of all-electric type in recent years.
