Plastic Injection Moulding Services We Offer in Bristol
Stephens Plastic Mouldings provides complete project coverage. Our in-house teams work closely with clients from initial concept to finished part assembly.
We create high-precision injection mould tools using CNC machining and CAD-based simulation. Tooling is handled in-house, reducing lead times and ensuring performance longevity.
We assess part geometry, tolerances, wall thickness, and materials during the design phase to ensure efficient, repeatable production and reduce risk during scaling.
With a range of press sizes and modern equipment, we mould everything from lightweight enclosures to heavy-duty structural components using ABS, PA, PP, PC, and custom polymers.
Value-added processes include ultrasonic welding, part labelling, component kitting, and sub-assembly - ensuring your part arrives finished and functional.

Injection Moulding: Precision at Scale
Plastic injection moulding is one of the most reliable ways to produce high-quality, high-volume plastic components. The process involves injecting molten thermoplastic into a precision-machined mould, then rapidly cooling and ejecting the finished part. It’s fast, scalable, and repeatable – perfect for industries where quality and consistency matter.
For Bristol-based manufacturers, this means:
- Reduced part-to-part variation.
- Faster production cycles.
- Cost-effective manufacturing at scale.
- Design freedom for complex or multi-functional parts.
At Stephens Plastic, we support both short-run and long-term projects – backed by expert guidance and responsive customer service.
