About Air Spring Actuator

According to the structure of the air bag, the air spring can be divided into three types: bag type, membrane type and composite type.

Bladder air spring
The bladder-type air spring consists of a rubber bladder with cords and compressed air enclosed in it. The inner layer of the airbag is made of air-tight rubber, while the outer layer is made of oil-resistant rubber. Airbags are generally made of two convolutions, but there are also single convolution or three or four convolutions. The more the number of convolutions, the better the elasticity. There is a steel waist ring/belt loop/ girdle hoop between the convolutions, so that the middle part will not expand radially and prevent the two sections from rubbing against each other. The upper and lower covers of the airbag seal the airbag.

Membrane Air Spring

The airtight air bag of the membrane air spring is composed of a rubber diaphragm and a metal pressing part. Compared with the bladder type, its elastic characteristic curve is ideal, because its stiffness is smaller than that of the bladder type, and the natural vibration frequency of the body is lower; and the size is smaller, which is easy to arrange on the car, so it is mostly used in cars.

Composite air spring
From a structural point of view, the composite air spring is a type between the capsule type and the membrane type. It combines the advantages of the above two types of air springs and has a lower spring stiffness, but the manufacturing process is complicated.

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.
