What Can Injection Moulding Be Used For?
Plastic injection moulding is the ideal method for producing complex or high-volume plastic parts with a high degree of accuracy.
Using a machined mould, molten plastic is injected into a closed cavity under pressure, then cooled and ejected as a finished part.
This repeatable, high-speed process is used across industries in Slough for:
- Electronic enclosures and switch housings.
- Pharmaceutical and laboratory trays.
- Logistics packaging clips and handles.
- Consumer product casings and components.
- Automotive interior and under-bonnet parts.
Injection moulding offers predictable quality, low cost per part (at volume), and wide material choice – making it a scalable, sustainable solution.
