The working principle of the injection molding machine is similar to the infusion principle of the syringe. It is the process of injecting the plasticized plastic in the molten injection blowing machine state (i.e. viscous flow state) into the closed injection mold cavity at high pressure and high speed with the help of the thrust of the screw (or plunger). After cooling and solidification, the plastic injection blowing machine products with almost the same shape as the mold cavity are obtained. Injection molding is a cycle process, each cycle mainly includes: quantitative feeding à melting and plasticizing à pressure injection à mold filling and cooling à mold opening and taking parts. Take out the plastic part and close the mold again for the next cycle.injection blowing machine
