The working principle of a molding machine is similar to that of a syringe used for injection. It uses the thrust of a screw (or plunger) to inject melted plastic that has already been plasticized (i.e. viscous state) into a closed mold cavity. After solidification and shaping, the product is obtained.
Injection molding is a cyclic process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and part extraction. After removing the plastic part, close the mold again and proceed to the next cycle.
