The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (that is, the viscous flow state) plastic into the closed mold cavity. The process of obtaining products 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 opening and taking. After removing the plastic parts, the mold is closed again for the next cycle.
