This video describes the 4 main stages of the Plastic Injection Moulding Process. The process works by heating and injecting plastic material under pressure into a closed metal mould tool.

The mould tool, which can be made from aluminium alloy or hardened steel for example, provides the shape of the plastic part to be produced.

Stage 1 of the Plastic Injection Moulding Process is where with 2 parts of the mould tool firmly clamped together under pressure plastic granules are fed from hopper into the barrel and rotating screw of the injection moulding machine. These plastic granules are then made into a molten plastic liquid using heat, friction and force.

As the screw is rotated the molten plastic is forced forward through a check valve towards the mould tool. By pushing the material to the front, the screw is forced backwards

In stage 2 of the Plastic Injection Process A hydraulic ram is used to force the screw forward so that the molten plastic material is injected into the closed mould tool.

Pressure is applied after the molten plastic material has been injected into the mould to make sure that all of cavities and spaces have been filled.

In stage 3 of the Plastic Injection Moulding Process The Plastic Injection Moulding tool is held closed under pressure to allow the plastic material to cool and set hard in the mould tool cavity.

In stage 4 of the Plastic Injection Moulding Process as the screw begins moving back for the next moulding the tool is opened. The opening of the tool and the use of e.g. air blast, a plate or rods, mean that the finished plastic moulding is ejected. The mould is then closed and the whole cycle begins again for the next moulding.
