Do you provide FAI / PPAP / COC / material certificates?
Yes. We can provide FAI, COC (Certificate of Conformance), and material certificates as part of the shipment documentation when required. PPAP-related documents can also be supported for customer programs that require them. The exact document set is confirmed during quotation and onboarding.
What we typically provide
→ COC/COA: confirmation the shipped lot meets agreed requirements
→ Material certificate: material grade/heat/batch information (as available/required)
→ FAI (First Article Inspection): first-sample dimensional verification (scope agreed)
→ PPAP package items: provided per customer requirement level and NDA
What affects the document package
√ Customer requirement (standard pack vs full pack)
√ Sampling plan (per piece vs per lot)
√ Whether gear charts (profile/lead/pitch) are required
√ Confidentiality/NDA and customer-specific templates
How we make reports useful
We align charts to your functional datums and critical characteristics so you can see:
1. Where the deviation occurs (shape vs slope)
2. Whether it’s stable or drifting (process consistency)
3. What the risk is for noise/backlash/life (when relevant)
Steps
1. Tell us the required documents in your RFQ
2. Confirm submission format (PDF, portal, template)
3. We include the document pack in the quote and delivery plan
4. Documents are released with shipment (or at sample approval stage)
