Contract Moulding

Contract moulding allows you to leverage our production capacity, engineering expertise, and cost-advantaged South African manufacturing without replacing your existing tooling investment. You supply the mould — we handle everything else: setup, maintenance, material procurement, injection moulding, quality inspection, and packaging.

This is the fastest route to reducing your per-part production cost. By moving production of your customer-owned mould to our Johannesburg facility, most clients achieve 40–60% reduction in unit cost compared to their current US or UK contract moulder — without any tooling investment.

The Mould Transfer Process

  1. Initial Consultation: You share your current part drawing, annual volume, and resin specification. We provide a production cost estimate.
  2. Mould Shipping: Your mould is shipped to our Johannesburg facility. We can advise on freight forwarding and customs documentation.
  3. Mould Audit: We inspect the mould and provide a written condition report within 3 business days of receipt.
  4. Trial Production: We run trial shots, establish process parameters, and produce first-article samples for your approval.
  5. Production Agreement: Once first article is approved, we agree on production schedule, pricing, and quality requirements.
  6. Ongoing Production: Regular production runs with documented quality records and mould maintenance logs.

Move Your Mould. Cut Your Cost.

If you have an existing mould currently running at a US or UK contract moulder, we can almost certainly produce the same part for significantly less. Send us your current part drawing and annual volume for a cost comparison.
