Quality & Inspection
Drawing-Based Checks
Critical dimensions, thread fit, burrs, surface damage and packing condition are reviewed according to drawing and RFQ notes.
Inspection Scope
Calipers, gauges, thread checks and visual inspection are used when suitable. Inspection reports are available when agreed before production.
FAQ for RFQ Buyers
What files should I send for quotation?
Please send STEP, STP, PDF, DXF, DWG, IGES, or sample photos. A complete RFQ should include material, quantity, tolerance, surface finish, and target delivery requirements.
Can you protect confidential drawings?
Yes. Customer drawings are used only for quotation, manufacturability review, production communication, and inspection planning.
Can you review manufacturability before production?
Yes. We review geometry, material, tolerance, threads, finishing, and inspection requirements before confirming price and lead time.
