Applications of Rubber Air Springs in Modern Engineering​​
​​1. Lifting Equipment​​
Traditional lifting systems rely on hydraulic or pneumatic cylinders, which suffer from ​​bulky designs, high maintenance, and leakage risks​​. Rubber air springs revolutionize lifting equipment by offering:
​​Compact Installation​​ – Requires minimal space compared to hydraulic systems.
​​Leak-Free Operation​​ – No fluid seals mean zero risk of hydraulic leaks.
​​Maintenance-Free Durability​​ – Long service life with no lubrication or frequent repairs.
​​Easy Replacement​​ – Simplified assembly and disassembly processes.
Rubber air springs are ​​rapidly replacing conventional cylinders​​ in cranes, elevators, and material handling systems, improving efficiency and reliability.

​​2. Vibration Reduction Systems​​
Rubber air springs excel in ​​high-frequency vibration isolation​​ and ​​low-frequency damping​​, making them ideal for:
​​Vibrating Screens​​ – Minimize structural vibrations in mining and aggregate processing.
​​Luxury Vehicle Seats​​ – Enhance ride comfort by absorbing road shocks.
​​Industrial Machinery​​ – Protect sensitive equipment from operational vibrations.
Their ​​self-adjusting stiffness​​ ensures stable performance across varying loads, maintaining safety and precision in critical applications.

​​3. Other Key Applications​​
​​Precision Equipment Transport​​ – Safeguards delicate instruments (e.g., missile systems, control units) from shock damage during transit.
​​Field Maintenance Supports​​ – Lightweight and portable, ideal for stabilizing vehicles and machinery during repairs.
​​Aerospace & Defense​​ – Used in landing gear and sensitive payload stabilization.

In 2017, we launched a collaboration with High Tech of US customers to customize the products of our customers and the logo of our customers. Every year, there are about 10,000 orders. In continuous cooperation, the products meet the international inspection standard ISO/TS16949:2009, and the customers are very satisfied with the products produced. 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.
