quality assurance
1、 Established a complete quality management and production management system
1. Regular audits of our raw material suppliers are required, and the raw materials must be tested according to our IQC acceptance standards and the supplier's COC report to strictly ensure the quality of the raw materials.
2. Improve employees' quality awareness, standardize their operations, and ensure standardization in their operations.
During the production and manufacturing process, self inspection and sampling are combined, and multiple layers of inspection are carried out for semi-finished products, finished products, and shipped products.
4. Our company has a group of professional technical personnel in production and research and development, constantly improving our ability to control product quality, and achieving prevention first and continuous improvement.
2、 The company obtained SGS ISO9001 (2000 version) quality system certification in 2002 and 2006 respectively.
