HCH is strengthening its group audit functions as a mean of reinforcing its manufacturing. To guarantee the quality management is effectively implemented and maintained, HCH conducts internal audits at planned intervals to determine whether the quality management system conforms to the planned arrangements, the requirements of International standard and what established by HCH. The Scope of Internal Audit:

1. Review of requirements related to the product: Product requirements are defined. Reviewing the order and contract requirements and resolving the detailed problem to ensure HCH bearings meet specific requirements.

2. Quality management system audit: HCH Internal Audit department audits its quality management system to verify compliance with technical specification and any additional quality management system requirements, also audit each manufacturing to determine its effectiveness.

3. The department should audit products at appropriate stages of production and delivery to verify conformity to all specified requirements, such as product dimensions, functionality, packaging and labeling, at a defined frequency.

4. Continuous Improvement: Evidence demonstrates the use of data (ie: First Pass Yield, Final Test, In-process Cpk, etc.), past experience, and lessons learned may be requested to show continuous improvement of quality management system.
