Working Principle Of Injection Moulding Machine

- Jan 20, 2018-

Injection molding machine working principle and injection syringe similar, it is the use of screw (or plunger) of the thrust, the plasticizing of the molten state (that is, viscous flow state) of plastic injection into a closed cavity, after the solidification of the process of obtaining products.

Injection molding is a cycle of the process, each cycle mainly includes: quantitative feeding-melt plasticizing-pressure injection-mold cooling-open mold pickup. Remove the plastic parts and then close the mold, for the next cycle.

Injection Molding Machine Operation project: The Injection molding machine operation project includes the control keyboard operation, the electrical control system operation and the hydraulic system operation three aspects. respectively, the injection process action, feeding action, injection pressure, injection speed, ejector type selection, barrel temperature monitoring, injection pressure and back pressure adjustment.
