Zhaoguang's Quality Department's "Red and Black List" system is renowned in the industry—quality data published monthly is accurate to a 0.01% defect rate. A team of four dedicated quality experts utilizes CNC inspection equipment, X-ray flaw detection, and other equipment to implement 12 quality checkpoints, from incoming raw materials to finished product shipment. Their innovative "Three Inspections and Three No's" principle (self-inspection, mutual inspection, and specialized inspection; no acceptance of defective products; no production of defective products; and no circulation of defective products) has maintained a product qualification rate above 99.7% for five consecutive years.

"Quality isn't measured by inspection, but by design," Quality Manager Wang Fang emphasized at the standards implementation review meeting. The company's established "Quality Traceability Cloud Platform" precisely identifies the production parameters and responsible individuals for each batch of products. The newly launched "Quality Star" rating system, launched in 2025, directly links employee performance to quality indicators, fostering a culture of quality for all employees.
