What KOFON Motion Group does

KOFON Motion Group is a privately held Chinese industrial automation company founded in 2010 and headquartered in Huanggang, Hubei Province, that designs and manufactures high-precision motion control components — including planetary gearboxes, strain wave (harmonic) gears, spiral bevel gearboxes, planetary roller screws, and integrated motion modules for AGV/AMR and humanoid robots. Its technology stack is built around full vertical integration: precision hot-die forging of 20CrMnTi alloy steel, in-house heat treatment co-developed with AICHELIN of Austria (deep carburizing, quenching, plasma nitriding), ultra-precision cylindrical gear grinding via KAPP NILES technology applied as standard across mid-range lines, and patented planetary carrier designs (Master CagedSpindle) deployed across the KPG and KPH servo gearbox families. The company applies claimed 15+ years of space-grade micromechatronics expertise to industrial and humanoid robotics applications, with output efficiency rates of up to 97% and service life exceeding 20,000 hours.

The business model is hardware-led B2B: KOFON sells standard catalog products as well as customized solutions (15-day lead time for 1-50 customized units; 5 days for standard) through direct sales from its China headquarters and a global network of regional agents, with engineering consulting and technical training wrapped around pre-sales. Pricing is quote-based and not publicly disclosed. End markets span robotics, intelligent logistics (AGV/AMR), tooling machines/CNC, semiconductor manufacturing equipment, medical equipment, new energy equipment manufacturing, laser processing, and packaging/printing machinery — a horizontal segmentation approach with named enterprise customers such as Honor (Huawei subsidiary, supplying joint actuation modules for the "Flash" humanoid robot) and a German tooling machine OEM that reported 30%+ motion precision improvement and 20% efficiency gains. KOFON operates from a 50,000 m² Hubei manufacturing facility built with a €25 million investment, aligned to an annual capacity of 300,000 precision servo gearbox units, supports a 1,080+ global workforce (380+ technical engineers), and markets globally through an 11-language website, a KDP online design tool, and participation in eight or more major international trade shows including AUTOMATE (USA), SPS (Germany), and Smart Factory+Automation World (Korea).
