Focusing on the establishment, maintenance and promotion of the management system, supplemented by document control and promotion of quality activities, we continuously promote product quality improvement.

From product quality design to supplier quality management to process quality improvement, we comprehensively plan and continuously improve the company's quality management level.

Select, evaluate and develop qualified suppliers, and steadily improve supplier product quality and management through performance assessment of incoming materials, supplier audits and coaching, ultimately achieving a "win-win" situation for the group and suppliers.

Establish a comprehensive inspection model of incoming material inspection, first piece inspection, process self-inspection/mutual inspection, process inspection, and finished product inspection to ensure product quality.
