Custom moulding is for bespoke plastic parts made to your requirements, including projects that start from nothing more than a physical sample, a sketch or an idea.

What is Custom Injection Moulding?

Custom injection moulding means producing plastic parts designed specifically for you, rather than off-the-shelf items. That might mean working from your finished CAD, improving a rough concept, or reverse-engineering an existing sample part where no drawing exists.

If you have a sample but no drawing, we can measure and model it, design a tool to match, and put it into production.

Who This Service Is For

  • Businesses with a bespoke part and no existing supplier.
  • Customers who have a sample but no drawing.
  • Start-ups developing a brand-new product.
  • Companies needing custom assemblies, not just single parts.

Common Problems We Solve

  • “We have a sample but lost the drawings.” We reverse-engineer it.
  • “We only have a rough idea or sketch.” We help develop it into a manufacturable part.
  • “We need a one-supplier solution.” Design, tooling and moulding in-house.
  • “We need parts plus simple assembly.” We can handle inserts, over-moulding and assembly steps.

Our Process

Capture the part

From a sample, sketch or CAD, we define the part, reverse-engineering where needed.

Design & DFM

We refine it for manufacture. See tool design.

Tooling & sampling

We build the tool and produce approval samples.

Production

We mould your bespoke parts to the volumes you need.

Capabilities, Materials & Tolerances

Indicative capability. Every project is reviewed individually, so talk to us about your specific tolerances and materials.
