Automotive Parts Manufacturer: What OEMs Should Verify Before Sourcing

When sourcing an automotive parts manufacturer, OEMs should verify more than price: IATF 16949 certification, PPAP discipline, traceability and process control. We break down the audit checklist a buyer actually needs.

What separates a real automotive supplier

IATF 16949 is table stakes, not a differentiator. The real question is scientific molding capability, Cpk on critical dimensions, and a documented escalation path when a dimension drifts. We run Cpk≥1.33 on safety-relevant features.

Our automotive coverage

From die-cast engine valve covers to insert-molded connectors and interior trims — one supplier for the whole adjacent system, not three vendors with three failure points.
