We provide plastic injection moulding for UK businesses that need custom, technical and small plastic components, backed by in-house mould tool design and toolmaking, all from our Haverhill base in Suffolk.
What is Plastic Injection Moulding?
Plastic injection moulding is a manufacturing process where molten plastic is injected under pressure into a steel or aluminium mould tool, where it cools and solidifies into a finished part. Once the mould tool exists, parts can be produced repeatedly with excellent consistency and at a low cost per part, which is why injection moulding is the go-to process for plastic components made in volume.
Because we design and build the mould tools ourselves, we control the whole journey from part design to finished component. Read more in What Is Plastic Injection Moulding?
Who This Service Is For
- Product designers and start-ups bringing a new plastic part to market.
- Engineers and manufacturers needing a reliable UK moulding partner.
- Companies replacing an overseas supplier with shorter, more reliable UK lead times.
- Businesses needing low to medium volumes rather than only huge runs.
Common Problems We Solve
- “We have a design but no one to make the tool and mould the parts.” We do both in-house.
- “Our overseas lead times and communication are unreliable.” UK manufacturing keeps you close to your supply.
- “We're not sure the part can actually be moulded economically.” We give honest design-for-manufacture feedback.
- “We only need a few thousand a year.” We're set up for low and medium volumes.
