We design injection mould tools for manufacture, combining part design-for-manufacture feedback with sound gating, venting and cooling strategy, so the tool runs well from the first shot.

What is Mould Tool Design and Development?

Mould tool design is the engineering stage that turns a plastic part design into a workable mould tool. It decides where the plastic enters the cavity (the gate), how air escapes (venting), how the tool cools, where the part splits and how it ejects. Get these right and you get stable cycles and good parts; get them wrong and you fight defects forever.

We bring design-for-manufacture (DFM) thinking to your part early, adjusting wall sections, draft angles and rib design before any steel is cut.

Who This Service Is For

  • Designers wanting expert input before committing to tooling.
  • Companies whose parts have defect or warpage problems.
  • Engineers needing DFM feedback on a CAD model.
  • Anyone wanting tool design and build from one supplier.

Common Problems We Solve

  • “We're not sure our part is designed to be moulded well.” We review and improve it.
  • “We keep getting sink marks, warpage or weld lines.” These are often design and gating issues we can solve.
  • “We want to minimise cost per part.” Good tool design improves cycle time and yield.
  • “We need multi-cavity tooling.” We design for balanced filling across cavities.

Our Process

Part review (DFM)

We assess wall thickness, draft, ribs and features for moulding, and suggest improvements.

Tool concept

We define cavity layout, gating, venting, cooling and ejection strategy.

Design sign-off

We confirm the tool design and approach with you before build.

Handover to build

The design feeds straight into our toolmaking.
