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.

ISO 9001:2015

Strict Quality Control

We utilize 3D coordinate measuring machines (CMM) to precisely verify product dimensions and ensure full compliance with customer specifications. Before shipment, a full visual inspection is conducted to confirm all surfaces are free of scratches, dents, or damage.

To protect the products during transit, we use high-strength corrugated boxes and bubble wrap, enhancing shock resistance and load-bearing capacity. Custom packaging solutions are also available based on client requirements to ensure the products arrive safely and in perfect condition.
