Jiangsu Sunzo's Dacromet disc springs utilize high-performance materials such as Inconel 718 and SUS316, which exhibit exceptional mechanical properties and corrosion resistance, enabling long-term stable operation in harsh environments. Combined with advanced Dacromet surface treatment technology, these springs demonstrate outstanding corrosion resistance, ensuring reliable performance even under high humidity and extreme temperature fluctuations. The Dacromet surface treatment technology creates a uniform, dense protective film on metal surfaces, effectively preventing corrosion. Compared to traditional surface treatment methods, this technology offers superior corrosion resistance, enhanced wear resistance, and extended service life. Additionally, the springs feature variable stiffness characteristics that allow for nearly linear, decrescent, increscent, zero, or even negative stiffness configurations to meet diverse operational requirements. This variable stiffness capability is a hallmark of Jiangsu Sunzo's Dacromet disc springs, enabling automatic stiffness adjustment according to load and deformation demands for optimal cushioning and shock absorption. In practical applications, this feature significantly improves equipment operational stability and reliability while reducing failure rates and maintenance costs.

With outstanding product performance and premium services, Jiangsu Sunzo's disc springs have been widely adopted in numerous projects both domestically and internationally, serving global industry leaders such as KnorrBremse, China CRRC, and Puran Brakes. These successful cases fully demonstrate Jiangsu Sunzo's technical prowess and market recognition in the disc spring sector. As a leading global supplier of commercial vehicle braking systems, KnorrBremse imposes stringent requirements on product quality and performance. Jiangsu Sunzo's designation as a KnorrBremse supplier vividly highlights the superior quality and performance of its products. China CRRC, a leading enterprise in China's rail transit equipment manufacturing industry, employs its products extensively across domestic and international rail transit applications. The integration of Jiangsu Sunzo's disc springs into China CRRC's products further attests to the company's technical expertise and market position. Puran Brakes, a renowned domestic braking system supplier, has also achieved remarkable success through its collaboration with Jiangsu Sunzo. These achievements have not only generated substantial economic benefits for Jiangsu Sunzo but also strengthened its corporate brand reputation.
