Our company has passed the ISO9001:2008 quality management system certification, and with this as the core, we have built a scientific and rigorous overall quality inspection policy. We have introduced an advanced QC engineering quality management system to comprehensively cover the entire process of inspection from raw material procurement to finished product delivery, ensuring that every link meets high quality requirements. By continuously optimizing processes and strengthening execution, we not only effectively improve the stability and reliability of product quality, but also continuously promote the soundness and improvement of the quality management system. This systematic management method enables us to efficiently serve customer needs, providing a solid guarantee for the excellent quality of products, and also laying a solid foundation for the company's sustainable development.

We adopt the most advanced international level of production and inspection equipment to meet the needs of many domestic and foreign customers. A series of high-tech testing equipment such as metallographic microscope, carbon sulfur analyzer and high-frequency wear resistance testing machine have been introduced to ensure that all raw materials meet the technical requirements of product parts production before mass production. Through metallographic microscopy, we can accurately analyze the microstructure of materials; the carbon and sulfur analyzer is used to strictly control the carbon and sulfur content in raw materials; The high-frequency wear resistance tester simulates the actual use environment to verify the wear resistance of the material. In addition, we implement the whole process management using PDCA cycle and AQL standards to ensure that every step meets the highest quality standards. At the same time, the application of Vickers hardness tester enables us to test the hardness, high-frequency hardening effect, and carburizing surface distribution of various materials with high precision, thereby further improving the reliability and durability of products. These advanced equipment and management methods together provide a solid guarantee for us to create high-quality products.

We have an experienced and professional quality team that is committed to ensuring that every product meets the highest standards. The company regularly conducts systematic training for production employees to ensure that they can operate equipment more standardly and efficiently and produce high-quality chain products. At the same time, our quality team conducts inspection on every step of chain production, from raw materials entering the factory to finished products, every link has undergone strict quality control. Through this all-round and full-process quality management, we not only ensure the consistency and reliability of our products, but also provide customers with trustworthy products.
