CQI-27 Casting System Assessment

Independent Second-Party CQI-27 Foundry Audit

CQI-27 is the AIAG Special Process: Casting System Assessment. AIAG states that it provides requirements for foundry suppliers of OEM automotive castings and focuses on common process requirements and failure modes associated with non-conforming castings.

Resitech Solutions conducts CQI-27 supplier assessments for applicable casting operations.
