Manufacturing scope

We operate two production shifts and manufacture moulds up to 15 tonnes and 1.8 × 1.5 metres. Four injection moulding machines are available for mould trials. Project size, machine availability and trial requirements are confirmed during quotation and project planning.

Project control

Documented reviews from design approval to shipment.

Each project follows defined stages: DFM review, design approval, tool-steel procurement, mould manufacturing, T1 mould trial, dimensional inspection, sample review and follow-up trials where required. Reports, open-item lists and sample approvals keep decisions traceable.
