Lifting the chain, what people think of is usually a bicycle chain. However, in the Donghua Chain Group of the Yuhang Economic Development Zone, this “chain kingdom” produces almost all chains that you can think of or cannot imagine except the bicycle chain.

“Chain Kingdom” has become a model of regional transformation and upgrading. These chains are used in various fields such as escalators, oil well chaining, high-speed rail machinery, timber transportation and other machine tools, food, and aviation. After a lot of research and development and innovation, at present, Donghua's chain products are extremely rich. There are a total of more than 7,000 varieties and more than 10,000 kinds of specifications. It solves customer problems in a package and therefore has achieved a good reputation both at home and abroad.

The small chain is made into a big industry. The success of the Donghua Chain is a microcosm of Yuhang’s commitment to the development of the real economy and the creation of a strong industrial area. It reflects the hard work spirit of Yuhang’s all-encompassing community.

“At present, our Tung Wah chain is working hard for its own brands to fully enter the international market!” Xuan Bihua, head of the company, said recently that as the first domestic chain manufacturer to enter the aviation industry, the total export volume of the Donghua chain reached more than 7,000 million yuan in 2011. In the past two years, it has shown an annual growth rate of 30-40%, which has become one of the models for regional transformation and upgrading.

Innovation + practical work to open the industry journey From the physics principle, a fulcrum can pick up the earth; from the perspective of industry, a chain, is linking the world. Right now, the Donghua Chain Industry has manufacturing bases in China, Germany, and Japan, as well as global multi-point warehouse sales companies such as the Netherlands, the United States, and Thailand. The world-class companies such as Case New Holland, Hitachi Elevator and Sany Heavy Industry can all see the Donghua Chain. In particular, employees are proud of: "Water Cube, Shanghai-Hangzhou high-speed rail, Nanhai oilfield have our chain!

The Tung Wah chain has strong R&D new products and depends on technological backing to continuously strengthen and enlarge the chain industry. It has established academicians and postdoctoral workstations, and has undertaken the national 863 project. It has filled the gaps in the manufacture of domestic chains and now has more than 40 national patents. item.
