Beginning of Changyuan Flex Company

China's oil pipeline engineers during the planned economy

Li Hongjun and his colleagues

Li Hongjun, founder of Changyuan Flexible Company, is a pipeline engineer in China. Since 1979, China’s infrastructure construction has been on the rise. The market demand for expansion joints inspired Li Hongjun’s idea of establishing an expansion joint company.

Because Lee Hongjun was an engineer in the factory during the socialist economic period of China, he joined the unemployed workers from the factory, rented a bankrupt state-owned factory, and began to produce metal expansion joints,dismantling joints and other products.


Mass production of expansion joints

Even with the high volume of orders, they didn't forget to test the pressure

Since 2000, China has joined the World Trade Organization, and foreign enterprises have invested and built factories in China. Various buildings have sprung up, and the expansion joints produced by Changyuan Company are very popular in the market.

The employees of Changyuan Company have always adhered to the work principle of being serious and paying attention to details. When they work, they carefully measure products with a ruler to ensure that the products they produce are exactly the same as the standards.


Development into a modern company

Changyuan's modern office building and modern factory

There are eight different functional departments in the office building

In 2008, the Henan Provincial Government proposed a bill aimed at helping small and medium-sized enterprises regulate their production and operation. Changyuan Flexible Company used this bill to establish a modern automated factory in the industrial Ghetto of Zhengzhou City.

Changyuan now has fully automatic rubber expansion joint production lines, bellows making machines and modern automatic welding equipment. These equipments have greatly improved the production efficiency and guaranteed the quality of the products.
