Physical and Chemical Testing Center

The quality management department of JNZC is fully responsible for the company's quality management work and has established project management, quality system management, on-site inspection management, physical and chemical testing center, and metrology & measurement center. The quality management team currently has 36 employees who are responsible for product quality inspection, physical and chemical analysis, quality management, and other work.


JNZC has always adhered to the requirements of ISO9001, IATF16949, AS9100D, and other quality management systems. We have built a high-standard and modern laboratory with huge sums of money. The physical and chemical testing center has passed the ISO/IEC17025 certification authorization. It is beneficial to participate in international laboratory recognition of bilateral and multilateral cooperation and promote the development of industrial technology and commerce.        

 

JNZC Physical and Chemical Testing Center adopt the industry's advanced testing and inspection equipment. The testing scope covers the chemical composition of metal materials, mechanical properties, torque testing, fatigue testing, non-destructive testing, microstructure, precision dimensions, salt spray testing, and other items.


High-frequency Fatigue Testing Machine - The high-frequency fatigue testing machine is used to implement the fatigue characteristics and fatigue life of metals, alloy materials, and fastener products under tension, compression, or tension-compression alternating loads at room temperature.


custom fastener manufacturer
