Advantage

1. Precise control precision: the air spring shock absorber provides precise height control by adjusting the internal air pressure. This feature eliminates fatigue and one-time setup problems common in other types of isolators.

2. Prolong the life of equipment: air spring shock absorber because of its special shock absorption principle, reflects a great advantage in the maintenance of equipment, when the traditional steel spring is impacted, will produce the phenomenon of self-vibration, the frequency of self-vibration can be directly transmitted to the equipment, resulting in loosening and damage of equipment. Air spring damping is much better, and it is even possible to achieve complete damping, significantly reducing equipment maintenance costs and extending equipment life

3. Wide range of action: air spring shock absorber vibration isolation load at each installation point from 10KG to more than 10 tons, can meet a variety of different production requirements. (Guomat air spring as an example, there may be differences between brands)

4. Superior shock absorption: Air spring shock absorbers provide superior vibration isolation among all types of vibration absorbers. The natural frequency of the system can be as low as 1 hz. The system's natural frequency can be even lower if an additional air storage chamber is added. In order to achieve the same effect, the static deformation of traditional spiral spring shock absorbers should be at least 230 mm.

5. Small footprint: Air spring shock absorbers can withstand the above loads at mounting heights as low as 50mm for vibration reduction. To achieve the same vibration isolation effect, the helical spring requires a free height of 135 mm to 645 mm. (Take Guomat air spring as an example, each brand may vary)

6. The use effect is stable: the air spring shock absorber is unique in that the natural frequency of the system does not change significantly when the load changes. This characteristic, combined with precise height control, makes it particularly suitable for mounting air spring shock absorbers at various mounting points on equipment with uneven loads.

7. Effective noise reduction: Air spring shock absorbers can effectively reduce the transmission of noise through the structure. Air spring shock absorbers themselves also do not produce noise because they do not have the flutter problems of traditional helical springs.

8. Wide use: air spring shock absorber can not only be used to protect the mechanical structure parts which produce vibration, but also widely used to isolate the vibration transmitted to precision machinery through the structure.

Guangzhou Guomat Air Spring Co., Ltd. is located in Guangzhou, about 15min’s drive from Baiyun Airport.

AIRSUSTECH is another brand of Guangzhou Guomat Air Spring Co., Ltd. 

AIRSUSTECH is focus on industrial air spring.

GUOMAT Factory gate：

Established in 2008, Our company covers 20,000㎡ and is located in Taihe Town Baiyun District. With the rapid development of our company, we are equipped with modernized workshop and advanced rubber air springs equipments now. We are the first company who started air spring business and has become one of the largest air spring manufacturing bases in China.

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.
