We mould engineering resins and commodity plastics including PP, ABS, PC, PC/ABS, PA, PMMA, POM and PS, and offer insert moulding, overmoulding, double injection (2K), printing, painting and assembly.
If you are looking for a reliable partner for automotive, medical, electronic or household parts, send us your drawing and our engineers will reply with a quotation and DFM suggestions.
Read MoreMould Design & Development
Our engineers review your part for manufacturability (DFM) and suggest changes to wall thickness, draft, gating and parting lines that reduce cost and risk. We then design the mould in full 3D using Pro-E, UG, SolidWorks and AutoCAD.

- Mould flow and cooling analysis
- Full 3D mould design for approval
- Material and surface finish recommendations
- Clear project schedule and weekly updates
Plastic Injection Mould Making
We build single- and multi-cavity moulds, family moulds, hot runner and cold runner tools, two-shot (2K) and overmoulds. Moulds are made from P20, H13, 718, S136, NAK80 or your specified steel on LKM, HASCO or DME bases, with a life of 50,000 to over one million shots.

- Medical and high-cavitation moulds
- Electronics and appliance housings
- Household, furniture and toy moulds
- Double injection (2K) and overmoulding
Injection Moulding
We mould your parts on 50–1300 ton machines and handle part weights from 0.1 g to 3500 g. Robots, conveyors and documented process settings keep quality consistent from the first shot to the last.

- Engineering resins and metal replacement
- Insert moulding and overmoulding
- Printing, painting and hot foil stamping
- Sub-assembly and final assembly
Rapid Prototyping
Test form, fit and function before investing in production tooling. We make prototypes in plastic and metal by CNC machining and rapid tooling, with painting and other finishing so samples look like the final product.
