The EMU with the highest operating speed in the world runs smoothly and comfortably. Thanks to the rubber damping products between the car body and the bogie, it seems that the car is padded with "Simmons".
Hong Kong Zhuhai Macao Bridge, the world's longest sea crossing bridge, stands proudly in the sea and calmly responds to hurricanes and waves, thanks to the installation of the largest rubber isolation bearings in the world.
These high-performance damping materials are all from ZZSD Advanced Materials Technology Corporation.
China's high-speed trains can run at high speed and smoothly, which is derived from high-performance air springs and other damping devices. This product, which is composed of rubber and metal, is "hidden" under the high-speed rail car body to absorb the vibration from the bogie and bottom rail.
More than 90% of the world's OEMs have adopted ZZSD products!
Today, it is not only the largest manufacturer of rubber damping products for rail transit in the world, but also the largest rubber isolation bearing in the world – the "sea calming needle" for major projects such as the Hong Kong Zhuhai Macao Bridge.
ZZSD has established a national high performance damping rubber engineering center and laboratory. The company has applied for 107 patents, including 61 invention patents, 38 utility model patents, and 8 PCT international patents, which have played an important role in promoting the technological innovation of China's automobile industry and improving its comprehensive competitiveness.
In 2013, in the face of fierce competition from 9 international giants, ZZSD stood out as a supplier of rubber isolation bearings for Hong Kong Zhuhai Macao Bridge by virtue of its self-developed ultra-high damping rubber isolation bearings;
"The rubber isolation bearing of the Hong Kong Zhuhai Macao Bridge is 1.77m long and 1.77m wide, with a bearing capacity of 3000 tons.
The bridge can withstand a super typhoon of magnitude 16, an earthquake of magnitude 8, and the impact of a 300000 ton ship
On the China Thailand high-speed railway project, the test beam with spherical steel bearing developed by ZZSD successfully passed the load test;
In 2017, the company provided air spring, primary spring and other full series rubber damping products for 65 trains of Melbourne Metro;
In 2017, fire retardant air springs meeting high standards were put into mass production;
In 2018, ZZSD acquired German high-performance rubber damping technology company;
The high-performance shock absorption rubber products developed by ZZSD are widely used in the global benchmark commercial vehicles, engineering machinery and industrial markets, and are the core suppliers of the world's first-line brand automotive OEMs.
In recent years, the company has focused on high-end automotive damping elastic element products, and continued to innovate in high-performance materials, new structures, advanced manufacturing processes, etc., especially in the research and development and application of high fatigue and high weather resistant rubber materials, high-strength new environment-friendly composite materials, breaking foreign monopoly in the research and development of new materials and high-end product applications, and solving a number of "technical bottlenecks", The market share in the subdivided fields has remained above 30%.
