Why Choose Stephens Plastic Mouldings?
Serving Peterborough, Huntingdon, St Neots and the wider East of England region, we combine local accessibility with the backing of a national ISO 9001-certified operation. You benefit from hands-on support, shorter lead times, and a consistent point of contact.
Our UK-based facility offers every service under one roof: CAD support, mould design, CNC-machined tooling, prototyping, and batch production. This control over process and quality means fewer delays and a smoother experience for you.
Need to test before committing? We offer rapid prototype tooling, small-batch trial runs, and iterative production options so you can validate your product before scaling up.
From standard plastics like polypropylene and ABS to more advanced polymers such as glass-filled nylons or TPEs, we'll guide you through the right material choice for durability, flexibility, or environmental exposure.
Our team works to your deadlines with reliable production windows, robust QA checks, and efficient shipping options to Peterborough and beyond. On-time delivery is a priority - not a bonus.
How the Injection Moulding Process Works
Injection moulding is the backbone of precision plastic manufacturing. A thermoplastic resin is heated and injected into a CNC-machined mould cavity, where it cools and hardens to the exact shape of your component.
The benefits include:
- Tight dimensional accuracy.
- Rapid production cycles.
- Consistent repeatability.
- Complex shapes and surface detail.
- Low material waste and high material variety.
Whether you manufacture building products, electronics, packaging, or consumer goods, plastic injection moulding is your route to scalable production and part uniformity.
