In addition, Huaswin will appraise and rank every supplier once a year to guarantee the suppliers provide the quality materials meeting Huaswin’s requirements. Furthermore, Huaswin continuously develops suppliers and promotes them to improve their quality and environment management basing on the systems of ISO9001.
Before accepting an order, Huaswin shall review and verify customer’s requirements to make sure that Huaswin has the capability to satisfy customers’ requirements including specification, delivery and other demands.
Preparation, Review And Control Of Manufacturing Instruction
Huaswin will evaluate all the requirements after receiving the customers’ design data and related document. Then, transfer the design datum into manufacturing datum by CAM. Finally, a MI which incorporates the manufacturing datum will be formulated according to Huaswin’s real manufacturing process and technologies. MI must be reviewed after preparation by independent engineers. Before the MI is issued, it must be reviewed by QA engineers and get approved. Drilling and routing datum must be confirmed by first article inspection before issued. In a word, Huaswin makes ways to guarantee that the manufacturing documentation is right and valid.
