Working principle:
The working principle of injection molding machine is similar to that of injector. It is a process of injecting molten plasticized plastic (that is, viscous fluid state) into a closed mold cavity with the help of the thrust of a screw (or plunger), and curing to obtain a product. Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding-melt plasticization-pressure injection molding-mold filling and cooling-mold opening and taking parts. Take out the plastic part, and then close the mold for the next cycle.
