Quality Management

Our Policy of Quality Control

Han Chang always insisting in providing the best quality to our clients. Our production process is aligned to customer needs and our quality chain begins with the first contact with customers and ends with the delivered product. We implemented ISO 9001 since 2005 to ensure we have the ability to produce excellent quality and applying 5S-methodology in our production line from raw-material to semi-finished products. In 2024, we are certificated by IATF16949.

Han Chang certified with ISO 9001 quality management system, ensuring stable and consistent quality in aluminum machining and CNC manufacturing.

Rigorous Quality Inspection

To guarantee every product meets design specifications, we use CMM (Coordinate Measuring Machine) for precise dimensional measurement. Before shipment, we also conduct 100% visual inspections to ensure all surfaces are free from scratches or dents, securing uncompromised product quality.

For packaging, we adopt high-strength corrugated cartons and protective bubble wrap, providing excellent resistance against impact during transportation. For customers with special requirements, we offer customized packaging solutions, ensuring products are delivered safe and damage-free.
