Quality Control

HOAN has established and implemented a quality management system with quality management and quality inspection departments. Product quality inspection includes sampling inspection and 100% inspection.

We have vibration shock test benches for vibration isolators, and the air permeability and waterproof performance of finished waterproof breathable valves are fully inspected according to technical specifications.
We agree on manufacturing standards, product acceptance standards and acceptance methods through contracts, technical agreements, etc., and clearly define technical service requirements in contracts or technical agreements; timely analyze problems when encountering them to ensure on-time delivery.
