Technical communication and design support in Germany, with mould manufacturing, trials and inspection in Shenzhen.
We review part geometry, resin behaviour, shrinkage, draft, gate location, cooling and mould construction before the mould design is released for manufacturing.
We provide schedules, manufacturing updates, trial plans, open-item lists and documented revision status.
We coordinate the T1 mould trial and follow-up trials, sample review, dimensional reports and customer-approved corrections.
We complete pre-shipment checks, documentation and the agreed spare-parts package, followed by technical support for installation, start-up and agreed after-sales requirements.

We review the mould construction against the approved part and tooling requirements. Trial samples are checked for dimensions, fit, function and appearance before final sign-off.
Final acceptance follows the agreed sample approval, dimensional reports and mould sign-off requirements.
The mould and agreed spare parts are inspected, protected and packed according to the confirmed shipping method.



The handover package is prepared according to the approved project requirements and shipment checklist.
