Guizhou firm powers global supply of advanced hydraulic parts

Founded in 2011, Guizhou Dingcheng Rongxin Technology Co has grown from developing bimetal composite materials into a leading domestic manufacturer of hydraulic system bimetal components and a global supplier of high-end hydraulic pump and motor parts.

China has long relied on imports for high-end hydraulic components, particularly high-pressure plunger pumps and motors. The company has tackled this challenge by prioritizing technology, investing over 7 percent of annual revenue in R&D, far above the industry average.

With a dedicated team of 40 researchers, the company has filed eight invention patents and more than 30 utility model patents, mastering critical technologies such as steel-copper bimetal casting.

"Digital transformation isn't optional for high-end manufacturers; it determines whether we can survive or not," said Zhou Wei, general manager of Dingcheng Rongxin. The company now runs a fully integrated digital management platform covering marketing, procurement, warehousing, finance, smart manufacturing, quality control, and decision support, streamlining the process from customer demand to production delivery.

Supported by government policies, special long-term sovereign bond financing, and recognition as a high-tech, specialized, and innovative enterprise, Dingcheng Rongxin has achieved annual growth of 50-60 percent for three consecutive years, with its products now widely used in excavators, pump trucks, rotary drills, ship cranes, and oil platforms, supplying both domestic OEMs and top international brands.
