Product Description
Machine Features:
Injection molding machine usually consists of the injection system, clamping system,
hydraulic drive system, electrical control system, lubrication system, heating and cooling
systems, security monitoring systems and other components.
Working principle of injection molding machine is similar with an injection syringe, it is by means of a screw (or plunger) of thrust, make good plasticized molten state (ie,
viscous state) good plastic injected into the closed mold cavity to obtain shaped
articles after curing.
Injection molding is a cyclic process, with each cycle including: quantifying feeder -
molten plastics - pressure injection - filling mold cooling - open mold and pick up
products. Take out the plastic parts and then go into next cycle operation.
