The working principle of the molding machine is similar to that of the syringe for injection. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (ie, the viscous flow state) into the closed cavity. The process of obtaining the product after curing and setting.
Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - filling mold cooling - mold extraction. After removing the plastic part, the mold is closed again and the next cycle is performed.
