service related FAQ’s

What is the minimum order quantity?2026-10-01T11:11:14+00:00

Tooling economics set the floor rather than a fixed MOQ. For parts on existing patterns we can quote from a few hundred pieces; new tooling normally justifies itself above 1,000 pieces.

How do you control casting defects?2026-10-01T11:11:14+00:00

Mold filling and solidification are simulated before tooling is cut. In production, charge chemistry, pouring temperature and cooling curves are logged per heat, so a deviation is corrected at the source rather than at final inspection.

Do you export, and how do you handle logistics?2026-10-01T11:11:14+00:00

We export to more than 40 countries through Inmore Global Trading. We handle export documentation, packing to ISPM 15 and sea or rail freight booking.

How long does a quotation take?2026-10-01T11:11:14+00:00

Send a drawing, a 3D model and the target annual volume. Our engineers return a manufacturability review, a tooling plan and a firm quotation — normally within five working days.

What is your typical lead time?2026-10-01T11:11:14+00:00

For repeat parts on existing tooling, four to six weeks ex-works. First articles on new tooling typically run ten to fourteen weeks depending on tooling complexity.
