Plastic Injection Moulding: How It Works
Plastic injection moulding is the process of forming plastic parts by injecting molten material into a custom-designed metal mould. Once cooled, the part is ejected, producing consistent shapes with minimal variance.
This process is ideal for:
- Complex geometries
- Tight tolerances
- Repeated production runs
- Minimal waste
- Fast cycle times
Whether you’re creating a simple housing or a multi-material assembly, injection moulding offers the best of speed, precision, and repeatability – especially when managed by an experienced UK supplier like Stephens Plastic.
