Some things you don't know about injection molding machines. How do professional injection molding machine manufacturers tell you the principle?
The working principle of an injection molding machine is similar to that of a syringe. It injects the plastic in the molten state (i.e., the viscous flow state) that has been plasticized into the closed mold cavity with the thrust of a screw (or plunger), and the product is obtained after curing and shaping.
Specifically, the working process of an injection molding machine mainly includes the following steps:
- Feeding: Add plastic pellets or powder into the barrel of the injection molding machine;
- Plasticizing: Through heating and stirring, the plastic pellets gradually melt into a viscous flow state;
- Injection: Under the push of the screw or plunger, the molten plastic is injected into the cavity of the mold.
