What is Mould Toolmaking?

A mould tool (or mould tooling) is the precision steel or aluminium block that shapes molten plastic into your finished part. It contains the cavity, cooling channels, gating and ejection system, and it's the single biggest factor in part quality, cycle time and cost per part.

Good toolmaking is what separates a reliable, long-running mould from one that produces flash, sink and rejects. Learn more in What Is Mould Tooling?

Who This Service Is For

  • Companies needing a new mould tool designed and built.
  • Businesses moving a product to UK manufacturing.
  • Customers needing tool modifications, repairs or maintenance.
  • Designers who want toolmaking and moulding from one supplier.

Common Problems We Solve

  • “Our existing tool produces flash or sink marks.” We diagnose and refurbish or re-cut tooling.
  • “We need a tool built and parts moulded by the same people.” We keep both in-house.
  • “We need a cost-effective tool for lower volumes.” We advise on the right tool type for your quantity.
  • “Our tool needs transferring or maintaining.” We manage tool transfer, storage and upkeep.

Our Process

Tool design & DFM

We translate your part into a manufacturable tool design, with design-for-manufacture (DFM) feedback to improve mouldability before any steel is cut. See mould tool design.
