Are you producing the plastic parts by injection molding machine? Or are you interested in knowing more about the injection molding machine? Here you can find more knowledge about the injection molding machines’ structure.

The Injection Moulding Cycle
The modern day process has developed and matured significantly to the level where fully automated, closed loop, microprocessor controlled machines are the ‘norm’, although in principle injection moulding is still a relatively simple process. Thermoplastic injection moulding requires the transfer of the polymeric material in powder or granule form from a feed hopper to a heated barrel. In the barrel, the thermoplastic is melted and then injected into a mould with some form of plunger arrangement. The mould is clamped shut under pressure within a platen arrangement and is held at a temperature well below the thermoplastic melt point. The molten thermoplastic solidifies quickly within the mould, allowing ejection of the component after a pre determined period of cooling time. The basic injection moulding process steps with a reciprocating screw machine are as follows.
