The working principle of an injection molding machine is similar to that of a syringe used for injection. It uses the force of a screw (or plunger) to inject a plasticized molten state (ie, viscous flow state) into a closed mold cavity. After curing and setting, the process of the product is obtained.
Injection molding machine operation items: Injection molding machine operation items include control of the keyboard operation, electrical control system operation and hydraulic system operation in three aspects. The injection process, the feeding action, the injection pressure, the injection speed, the ejection type selection, the temperature monitoring of each barrel section, the injection pressure, and the back pressure adjustment were performed.
