The working principle of the injection molding machine(1)


The working principle of the injection molding machine is similar to that of the syringe for injection. It is the process of injecting the plasticized molten plastic (i.e. viscous flow) into the closed mold cavity with the help of the thrust of the screw (or plunger), and obtaining the product after curing and shaping.

Injection molding(injection molding machine) is a cycle process, each cycle mainly includes: quantitative feeding - melting and plasticization - pressure injection - mold filling and cooling - mold opening and taking parts. After taking out the plastic part, close the mold again for the next cycle.

Injection molding machine operation items: injection molding machine operation items include control keyboard operation, electrical control system operation and hydraulic system operation. Select the injection process action, feeding action, injection pressure, injection speed and ejection type, monitor the temperature of each section of the barrel, and adjust the injection pressure and back pressure.
