Action program of standard injection molding machine

Nozzle forward → injection → pressure retaining → pre-molding → reverse shrinkage → nozzle backward → cooling → mold opening → ejection → needle withdrawal → door opening → door closing → mold closing → nozzle forward.ce Standard Injection Molding Machine

General china injection molding machine includes injection device, mold closing device, hydraulic system and electrical control system.plastic injection machine.

The basic requirements of injection molding are plasticization, injection and molding. Plasticization is the premise to realize and ensure the quality of molded products, and in order to meet the requirements of molding, injection must ensure sufficient pressure and speed. At the same time, due to the high injection pressure, a high pressure is generated in the mold cavity (the average pressure in the mold cavity is generally between 20 and 45 MPa), so there must be enough clamping force. It can be seen that the injection device and the clamping device are the key components of the injection molding machine.Standard Injection Molding Machine.standard injection machine.
