Built in-house.
End to end.
We design and fabricate precision injection moulds for watch components and industrial plastic parts. Our in-house tool room is equipped with CNC machining centres, EDM (spark erosion), and surface grinding machines to produce moulds with cavity accuracies within ±0.02mm. We work from your 2D drawings, 3D CAD files, or even physical samples to develop production-ready tooling.
What we deliver
What powers this service
The machines, methods and checks that sit behind every job we take on.
3-axis CNC
Core and cavity machining on Taiwan-grade VMCs. Cycle times tuned for harder mould steels.
Wire & Sinker EDM
Fine detail features, sharp corners and deep ribs that milling cannot reach.
Surface Grinding
Mould plate flatness and parallelism held within microns for leak-free shut-off.
In-house Try-out
Moulds tested on 50-tonne presses before dispatch — no surprises at your end.
From brief to dispatch
6 stages — each checkpoint signed-off before work moves to the next.
Design Review
Analyse your drawings or samples. Suggest design-for-manufacturing improvements.
Mould Design
Create 3D mould design with gating, ejection, and cooling channel layout.
Steel Selection
Choose mould steel grade (P20, H13, S136) based on volume and material requirements.
CNC Machining
Machine core, cavity, and inserts on 3-axis CNC centres.
EDM & Finishing
Fine-detail features via wire EDM and sinker EDM. Polish to required surface finish.
Trial & Approval
Run trial shots, measure parts, and iterate until your approval.

Questions buyers
ask us first
Quick answers to what typically comes up before we start a project. Something specific?
Ask a question arrow_forward
What file formats can you work with?
add
2D drawings (PDF, DWG, DXF) and 3D CAD files (STEP, IGES, Parasolid). We can also reverse-engineer from a physical sample.
How long does a new mould take?
add
Simple single-cavity moulds ship in 3–4 weeks. Multi-cavity production tooling typically takes 6–8 weeks including try-out.
Which mould steels do you use?
add
P20 for prototype and short runs, H13 for higher-volume work, S136 / NAK80 for optical and cosmetic parts. Steel is selected during design review.
Do I own the mould after payment?
add
Yes — the mould is delivered against its commercial invoice and you retain ownership. Storage on our floor is available if you run recurring batches with us.
