Engineering Support
Practical engineering review from part design through mold trials and sample validation.
We review wall thickness, draft, ribs, bosses, undercuts, parting lines, and molding risks before tooling starts.
Materials are reviewed against mechanical, appearance, temperature, environmental, and molding requirements.
We evaluate mold structure, cavity layout, gating, cooling, ejection, and production requirements before toolmaking.
Machining, fitting, assembly, mold trials, and adjustments are handled by our internal tooling team.
Initial molded samples are reviewed for dimensions, appearance, assembly, and function before production approval.
Quality Control
Inspection checkpoints help maintain consistency from project requirements to final shipment.
Drawings, specifications, critical dimensions, appearance standards, and inspection requirements are confirmed before production.
Initial parts are checked against agreed requirements before stable production proceeds.
Production conditions and critical part characteristics are monitored at defined stages during molding.
Finished parts are inspected for dimensions, appearance, quantity, and packaging before shipment.
