Injection molding machine injection molding (injection molding) is a method to make thermoplastic or thermosetting plastic uniformly plasticized in a heating barrel, and then pushed into a closed mold cavity by a plunger or a moving screw to form a plastic part.
What is the basic principle of injection molding machine?
The principle of injection molding of the injection molding machine is to take advantage of the extrudability and moldability of plastics to send loose pellets or powdered molding plastics from the hopper of the injection molding machine into a high-temperature barrel to heat, melt and plasticize, making it The viscous liquid melt is driven by the high pressure of the plunger or screw, and injected at a large flow rate through the nozzle at the front of the barrel into the closed mold cavity with a lower temperature. After a period of pressure-holding cooling and setting time, the mold is opened. The plastic part with a certain shape and size can be taken out from the cavity.
