The predecessor of Yuexin was the Aftermarket Division established by TSHI since 2013. In 2021, in response to the group's strategic planning, this division became an independent company. Founded in 2002, TSHI was among the first factories in China to possess gear grinding capabilities, and relying on TSHI's robust manufacturing strength, Yuexin has continuously accumulated experience, gradually emerging as one of the leading enterprises in domestic gear research, design, manufacturing, and repair.

We have successfully completed multiple customized products. Additionally, we have professional reverse engineering technology for gearbox remanufacturing and reliable component repair techniques. Our workshops are equipped with specialized cleaning, disassembly, sub-assembly, final assembly, and testing facilities. With rich experience in remanufacturing nearly 500 types of gearboxes and thousands of units, we also excel in remanufactured gearbox fault diagnosis, failure analysis, and optimization improvement.
