Injection mould tooling for plastic components, designed for dimensional accuracy and long production life.
We build injection mould tooling for plastic components — two-plate and three-plate, single and multi-cavity — designed around the shrinkage of the material you are actually moulding.
Mould cost is decided at the part-design stage, not the tool-design stage. Undercuts that force a side core, wall sections that will sink, and gate positions that weld-line across a cosmetic face are all cheaper to change on your drawing than in hardened steel. We raise them before quoting.
What we build
Specification
| Mould base | Standard or custom, to your machine platen and tie-bar spacing |
|---|---|
| Cavity and core | P20 pre-hardened, or hardened tool steel for abrasive material |
| Ejection | Pin, sleeve, blade or stripper plate to suit the part |
| Cooling | Circuits laid to hold cycle time, not added after the fact |
| Shrinkage | Applied per the grade you are running, on your confirmation |
| Finish | Polished, textured or as-machined per your requirement |
Process
Questions
It is a trade-off between tool cost and part cost. Higher cavitation lowers cost per part but raises tool cost and needs a larger machine. Tell us your annual volume and target part cost and we will work the number with you rather than guessing.
Yes. We take in moulds for cavity repair, core replacement, re-polishing and ejection rework. Send photographs of the damage and a sample of the defective part.
P20 pre-hardened steel covers most applications. For glass-filled or otherwise abrasive materials, or for high-volume tooling, we move to a hardened tool steel — the choice depends on the polymer and the production life you need.
