All staff actively participate and strictly implement the ISO9001-2015 quality management system.

Establish a quality control department dedicated to quality management, quality inspection, quality evaluation, quality improvement, and other related work. Make quality an important component of employee compensation.

Quality control points are set up in important links such as raw material procurement, production, and shipment to ensure quality. Including raw material incoming inspection, process inspection, and finished product inspection.

Strictly implement business processes, such as creating a sample book before formal production, and only proceed with formal production after the sample book is qualified.

All defective products generated during the production process are discussed by relevant departments to identify the problem points and propose final corrective and preventive measures.

Establish relevant files for each occurrence of adverse phenomena as pre employment training materials for new employees, focusing on key training projects to prevent similar incidents from happening.

Each department regularly conducts re education and training for employees to improve their quality.
