Our quality control starts from the source. We strictly screen raw materials and only cooperate with the most reliable suppliers in the industry to ensure the quality consistency and stability of raw materials. At the same time, we have formulated detailed raw material inspection processes and standards, and conduct random inspections in strict accordance with AQL standards to ensure that each batch of raw materials entering the production line meets the company's quality standards.

To continuously improve the level of quality management, we also regularly organize training and learning activities to enable employees to master the latest quality management concepts and methods, establish quality awareness, and make quality everyone's responsibility. Regularly collect problem points reported by clients to promote continuous improvement of quality; encourage employees to put forward quality improvement suggestions, form a good atmosphere of full participation, and jointly promote the continuous optimization of quality management. Not only that, we have also established a complete quality traceability system. Once a problem is found, we can quickly analyze and find the specific process links and responsible persons, take corrective measures in time, and ensure that the problem does not recur.
