Frequently Asked Questions
What quality certifications do automotive suppliers need?
Minimum: IATF 16949. Most OEMs require. Additional: ISO 14001 (environmental), customer-specific requirements (CSRs). Supplier scorecards affect business. New suppliers undergo 12-18 month qualification process.
What is PPAP and why does it matter?
Production Part Approval Process: documentation proving supplier can consistently produce parts to specification. 18 elements including control plan, FMEA, MSA, dimensional reports, material test results. Required before production. Without PPAP approval, parts cannot ship.
How do I calculate automotive silicone costs?
Material (40-60%), tooling amortization (10-20%), labor/overhead (20-30%), logistics (5-10%), profit (5-15%). Volume matters: 10k/year vs 100k/year changes economics 30-50%. Multi-year contracts reduce costs. Calculate total cost of ownership, not just piece price.
