What Nanjing Kangni Mechanical&Electrical does

Nanjing Kangni Mechanical & Electrical Co., Ltd. (stock code 603111 on the Shanghai Stock Exchange) is a Chinese mechatronics manufacturer founded in October 2000 and listed in August 2014, headquartered in Nanjing with approximately 3,000 employees including 800 R&D personnel. The company's core business is rail transit vehicle door systems — including sliding plug doors, pocket sliding doors, platform screen doors, gate machines, connectors, and motors — where it holds over 50% domestic market share in China and supplies major global rail vehicle manufacturers and metro operators including CRRC, Alstom, CAF, Škoda, and Deutsche Bahn. Beyond rail, Kangni operates a second growth business in new energy vehicle charging connection systems (charging guns, high-voltage connectors, PDUs, energy storage connectors) serving BYD, Chery, FAW, SAIC, Mercedes-Benz, and Yutong, and an incubation business in intelligent health (smart wheelchairs, medical equipment) and precision CNC forming gear grinding machines.

The company's go-to-market is enterprise-direct B2B sales, supported by 5 overseas subsidiaries (France, USA, Thailand, Brazil, Chile) serving as regional market development platforms and 24 domestic holding subsidiaries covering different product lines and customer segments. Pricing is quote-based and contract-driven, not publicly disclosed. Revenue is generated through hardware sales of door systems, NEV components, and precision machinery, plus recurring maintenance services and spare parts — aftermarket maintenance revenue reached 405 million RMB in 2023 (up 21.99% YoY). Technology differentiators include in-house development of core door components (controllers, motors, lead screws), the world's first SIL4 safety certification for a complete platform door system, and a PHM (Prognostics and Health Management) system using IoT and big-data analytics for condition-based maintenance. Production is anchored by 3 production bases with 82%+ CNC automation utilization, 40% robot application rate, and an intelligent manufacturing platform spanning CRM, SRM, PLM, ERP, MES, SLM, PMS, and QIS systems. Disclosed FY2025 revenue was approximately 4.187 billion RMB (~$580M USD), up from approximately 3.968 billion RMB in FY2024, with a Q3 2025 rail transit order backlog of 7.906 billion RMB.
