Why Can We Always Ensure Excellent Quality

Quality Control

Quality Assurance

The company has established a quality assurance system in accordance with international requirements to meet the needs of customers with excellent products and excellent after-sales service. As early as the end of 1999, it passed the ISO9002 quality certification, and completed the ISO9001:2000 version certification in 2002. While focusing on quality management, it started to establish the company's environmental management system. In 2003, it passed the ISO14001 environmental management system certification and became a double-certified enterprise in the same industry in China.

Based on technical cooperation with Japan Krosaki Harima Corp., we obtained more than ten related patent certificates.
