The Injection Moulding Process

The plastic injection moulding process is when plastic materials are placed into an injection moulding machine and melted. The melted plastics are then injected under pressure through a runner system into a cavity. Once the material has cooled down and solidified, it’s finally ejected from the mould as a finished part. To read about the process in full, see our article; plastic injection moulding process.
