​​Innovative Applications of Rubber Air Springs​​

1. Rubber air springs have become a transformative technology across multiple industries due to their superior performance and adaptability. In vehicle suspension systems, they form the core of advanced air suspension setups, increasingly adopted in premium buses, cars, and tractors. These systems automatically adjust ride height while maintaining consistent vehicle posture, leveraging the air spring's low natural frequency to deliver unmatched ride comfort. The exceptional vibration isolation protects both the vehicle and sensitive onboard equipment, while significantly reducing road impact forces by up to 35%, extending pavement lifespan. As China's air suspension technology matures and new bus quality regulations take effect, automotive applications are poised for substantial growth.
2. In lifting equipment, rubber air springs are revolutionizing traditional hydraulic systems. Their compact design requires 60% less installation space compared to conventional cylinders while eliminating leakage risks entirely. The maintenance-free operation and extended service life make them ideal for material handling applications, where they're rapidly replacing outdated hydraulic solutions.
3. For vibration control, rubber air springs excel in demanding industrial environments. They effectively isolate both high-frequency vibrations in machinery like vibrating screens (achieving 98% vibration reduction) and low-frequency oscillations in luxury vehicle seats. The specialized multi-ply reinforced construction ensures reliable performance even after 10,000 hours of continuous operation.
4. Recent technological advancements include smart pressure regulation systems, graphene-enhanced rubber compounds for improved durability, and modular quick-change designs that minimize downtime. With upcoming regulatory changes mandating air suspension in certain vehicle classes, rubber air springs are set to play an increasingly vital role in industrial and transportation systems worldwide.

This is our high recognition from American customers and also gives us Great motivation.

In 2018, we started cooperation with German GmbH, mainly industrial air springs, which are suitable for industrial equipment. We have successfully developed and produced the natural air-seal of the skin to reach the 700mm flanged air spring, the customer's annual demand is a few hundred.

With the development of business and demand for customers, our company introduced business with TomLog Corporation in 2010, our strategic cooperative partner in Taiwan. Then we developed air compressor program and air spring related business, in 2015, America Goodyear Corporation met with the transfer of shares in the North American plant, our company was granted with sale agent for air springs in China, providing more choice for our customers. Our company adopts the most advanced domestic air spring processing equipment and international production technology. Combined with unique production process, our company strictly execute international standards for production and spare no efforts to create the world-class products. We will endeavor to make air spring widely used at home and abroad, and let more and more customers to enjoy the best damping effect.
