Ensuring Excellence in Heat Treatment Processes
At IMPROV, we support manufacturing organizations in achieving compliance with the CQI-9 Heat Treat System Assessment, a globally recognized benchmark for quality and consistency in heat treatment processes. Developed by the Automotive Industry Action Group (AIAG), CQI-9 aims to establish best practices and ensure that heat-treated components meet the stringent quality requirements of industries like automotive, aerospace, and heavy machinery.
What is CQI-9?
CQI-9 is a technical standard that defines requirements for evaluating and improving the heat treatment processes used in manufacturing. It provides a structured assessment framework to ensure uniformity, traceability, and precision in heat-treated components, critical for safety and performance in high-stress applications.
This standard applies to processes like carburizing, quenching, tempering, annealing, and more, making it a vital tool for organizations focused on maintaining high-quality standards in their production lines.
Core Areas of Focus in CQI-9
- Process Control: CQI-9 emphasizes rigorous process controls, including equipment maintenance, process monitoring, and consistent documentation to maintain the integrity of heat treatment operations.
- Personnel Competency: The standard highlights the importance of skilled operators and supervisors in ensuring compliance with heat treatment protocols.
- Equipment Calibration: Regular calibration and maintenance of equipment are crucial to meeting CQI-9 requirements, ensuring precision in temperature and process controls.
- Continuous Improvement: CQI-9 encourages organizations to adopt a culture of continuous improvement through regular assessments, data analysis, and corrective actions.
