How Does Plastic Injection Moulding Work?
The injection moulding process uses a custom-built mould cavity to form heated plastic into precise shapes under high pressure. Once cooled, the plastic component is ejected and the cycle repeats. This fast, closed-loop system allows thousands of consistent, high-quality parts to be produced with minimal waste.
For manufacturers in Luton looking for both scalability and precision, injection moulding provides unbeatable cost-efficiency and design control.
