What it is

A small precision workshop that machines, finishes and maintains moulds and tooling used in injection moulding, rubber moulding and similar processes. Work includes new tools, modifications, repairs and polishing.

Your first three steps

  1. Talk to local moulders about the tooling and repair work they struggle to get done quickly
  2. Price up a small unit and second-hand CNC machining equipment, and build a simple cash flow forecast
  3. Line up two or three trial jobs or a subcontracting arrangement before you commit to the lease
Who pays

Plastic and rubber product manufacturers, moulding companies and engineering firms that prefer a local, responsive toolmaker.

How it makes money

Quoted price per tool, plus hourly or fixed-price repair and modification work. Regular maintenance for the same moulders helps keep the workshop busy between larger jobs.

Skills that help
  • Toolmaking or precision machining experience
  • CAD/CAM programming
  • Reading engineering drawings
  • Accurate quoting and project planning
Watch out for
  • Public liability, employer's liability once you hire, and cover for customers' tools while they are in your care
  • Machinery safety, risk assessments and fumes or coolant handling, so check the Health and Safety Executive guidance
  • Business rates, unit lease terms and any planning use class requirements, so check with your council
  • Large customers can pay late, so agree payment terms and consider deposits on new tools
  • Equipment costs are high, so compare buying second-hand, leasing and sharing space in an existing workshop
