What is your minimum order quantity (MOQ) for OEM manufacturing?

We do not have a strict minimum order quantity. We manufacture prototype quantities (10–50 pieces) as well as production batches up to 100,000+ pieces. Pricing improves with higher volumes due to setup cost amortization.

Do you work with small companies or only large OEMs?

We work with companies of all sizes, from engineering startups to established multinational OEMs. Clear drawings, defined technical specifications, and professional communication are the primary requirements.

How do you handle quality issues or dimensional deviations?

If any component does not meet drawing specifications, we either rework the part where possible or manufacture replacement components at no additional cost. Dimensional inspection reports are maintained for traceability.

Precision Machined Components Manufacturer for Global OEMs

Q: What drawing and file formats do you accept for OEM manufacturing?

We accept PDF drawings, DWG/DXF files (2D CAD), and STEP/IGES files (3D models). If only physical samples are available, we can reverse-engineer components with detailed measurement reports for approval.

Q: What is the typical lead time for sample and batch production?

Sample lead time is typically 7–14 days depending on component complexity. Batch production lead time ranges from 3–6 weeks depending on quantity, material availability, and machining processes. Final timelines are confirmed during quotation.
