(1) In October 2020, Kexing Chemical solved the global challenge of “cleaning after carbonitriding” for SKF’s Changshan plant.
(2) In 2021, Kexing Chemical was selected by SKF as the sole domestic supplier to replace foreign brands.
(3) In May 2024, Kexing Chemical creatively implemented the industry’s first “online impurity-removal oil management patent technology” in SKF’s “280-ton chip-fluid tank long-life management” project, thereby resolving the issue of “degraded cleaning performance” at SKF’s Xinchang plant caused by “oil adhesion on the outer ring” in the “Phase II Precision Grinding Line No. 63.”
