1. Injection molding processing requires a temperature adjustment system to meet product temperature requirements. The temperature adjustment system can be divided into two types: cooling system and heating system according to different conditions. Under normal circumstances, the temperature of the plastic injected into the mold is about 200 degrees, and the temperature of the injection molded parts when they are taken out of the mold cavity after forming is below 60 degrees.
2. After injection molding of thermoplastic plastics, the mold must be effectively cooled to promote the heat of the plastic to be quickly transferred to the mold, so that the injection molded parts can be ejected as soon as possible after cooling.
3. For some plastics with lower molten plastic viscosity and better fluidity, such as polyethylene, nylon and polyethylene, if the side walls of the injection molded parts are relatively thin, the mold can be naturally cooled. If the side walls of the injection mold are relatively thick, manpower is needed for cooling, so that the injection molded parts can be finalized as quickly as possible and improve work efficiency.
4. The temperature of the injection mold in each period needs to be supervised by the injection molding personnel, and the heating and cooling systems must be flexibly used to adjust the temperature of the mold. Only by achieving strict control can the plastic injection mold processing process be carried out smoothly and qualified products be produced.
