Air spring vulcanization process problems and solutions

At present, the commonly used production processes of air springs on the market are mainly vulcanized and pressurized.

1. Vulcanization type: Put the processed wheel hub and inertia block into the vulcanization mold.

(1) Fill the pre-calculated raw rubber material into the gap between the hub and the inertia block;

(2) Put the mold and the workpiece together on the heating plate of the flat vulcanizer (the vulcanizer has been pre-heated to the vulcanization temperature), press the mold under a certain pressure, and keep it for a certain period of time to stop the vulcanization;
(3) The vulcanization pressure, temperature and time need to be determined according to different rubber types and different formulations;

(4) Under the combined action of temperature and pressure, the raw rubber material begins to ablate, filling the gap between the hub and the inertia block, and the excess rubber material can be discharged from the running material to the port on the mold;

(5) The positioning of the workpiece and the accuracy of the position and shape after molding are guaranteed by the mold. In actual use, a suitable adhesive should be used, and appropriate surface treatment should be applied to the surface of the hub and inertia block to increase the firmness of the vulcanization bond. After vulcanization, the workpiece is removed from the mold. , the inertia blocks are firmly glued together, and the excess rubber is removed.

2. Pressurized type: Use pre-vulcanized damping rubber ring

(1) On the press, use a special press to press the rubber ring between the hub and the inertia block to a certain compression ratio;

(2) Appropriate adhesives should also be used, and the surfaces of the hub and inertia block should be properly treated to increase the firmness of the adhesive;

(3) The adhesive between the hub and the inertia block is a waste product after curing (some production processes need to process the outer band groove of the inertia block after curing).

Compared with the vulcanized type, the press-fit type applies a preload after adjusting the compression ratio of the rubber ring, and the adjustment amount is much larger than that of the vulcanized type, so that the rubber ring can work in the best condition.

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.
