Custom Metal Parts Ordering Process
WORKING WITH US IS SIMPLE.
1.Design Submission
Provide technical drawings (DWG, DXF, PDF, STEP, IGES)/samples + key specs (material, tolerance, surface treatment, quantity).
2.Quotation Review
Manufacturer evaluates feasibility and returns a detailed quote with unit cost, MOQ, and lead time.
3.Production Approval
Confirm final design adjustments (if any) and authorize production.
4.Quality Assurance & Delivery
Parts undergo dimensional inspection (with factory inspection reports) and are shipped with certifications (e.g., material test reports).
