Wuxi Best Precision Machinery Co., Ltd. - 无锡贝斯特精机股份有限公司

Wuxi Best Precision Machinery Co., Ltd. is a publicly listed precision-manufacturing company headquartered in Wuxi, Jiangsu Province, China. The company was founded on April 16, 1997, and listed on the Shenzhen Stock Exchange's ChiNext board on January 11, 2017, under stock code 300580, with reported registered capital of roughly RMB 500.54 million. Its registered address is No. 777 Jianzhu West Road, Wuxi, and it also operates facilities in the city's Binhu District. The company describes itself as a pioneer of China's tooling-and-fixture industry and is a council member of the China Machine Tool Industry Association's Fixture Division.

BEST's original business is precision components and tooling fixtures for forced-induction engines, producing turbocharger precision shafts, turbine and compressor impellers, and intermediate housings, together with precision parts for pneumatic tools and refrigeration compressors. Disclosed customers for these components include Garrett, Cummins, BorgWarner, SAIC, and Mitsubishi Heavy Industries. The company operates its tooling-fixture business through hundreds of CNC machining centers sourced from Germany, Japan and other countries, and has extended that fixture expertise into automated production-line equipment for automotive manufacturing.

In recent filings the company organizes its business into three segments: precision components and intelligent equipment; new-energy-vehicle components; and industrial machinery, which now includes an emerging line of humanoid-robot components. This third segment covers high-precision ball and roller screw assemblies, miniature screws, linear guide rails and linear actuators - motion-transmission parts used in robot joints and actuation systems. According to a July 2026 disclosure, this humanoid-robot component line remained at the sample stage, generating roughly RMB 223,000 in first-half-2026 revenue, equal to about 0.03 percent of total operating income, with the company cautioning that future returns from the segment carry significant uncertainty. BEST separately received a 2018 Jiangsu Province Science and Technology Award for work related to aerospace robotics technology.

Because BEST's own corporate website could not be reached directly during this review, the facts above were compiled from the company's regulatory filings on the Shenzhen Stock Exchange's disclosure platform and from licensed financial-data aggregators that republish those filings, rather than from company marketing pages.
