The 26th China International Industry Fair (CIIF) concluded at the National Exhibition and Convention Center (Shanghai) on October 16, 2026. Themed “Intelligent Economy, Boundless Smart Manufacturing,” this year’s edition brought together more than 3,200 enterprises worldwide, focusing on intelligent manufacturing and core robotic components. As a premier platform for showcasing new quality productive forces and connecting industrial value chains, the fair served as a hub for industry collaboration. Ningbo Boyin Harmonic Technology Co., Ltd. (BoyinDrive) presented its self-developed harmonic drives and integrated actuator modules at Booth 8.1H-E280, demonstrating precision transmission solutions for humanoid robots, collaborative robots, and semiconductor precision equipment, while engaging in technical exchanges and matchmaking with partners.
The harmonic drive is the “heart” of a robot joint, determining positioning accuracy, load capacity, and operational stability. BoyinDrive has cultivated deep expertise in digital harmonic drive manufacturing, achieving in-house R&D across materials, tooth profiles, flexible machining, and drive control. Its full-chain R&D system spans theoretical design, simulation, material development, process engineering, and testing, continuously optimizing performance to address challenges such as flexspline fatigue life, backlash, and torque density.
To tackle vibration, precision degradation, and component wear in robot joints, BoyinDrive developed a proprietary Digital Vibration-Suppression Tooth Profile based on a digital precision computation model to suppress vibration at the source. Mechanical simulation reduces component stress, improving motion accuracy by up to 30%. A flexspline mechanical model prevents tooth jumping and slows precision degradation over the service life, while digitally optimized lubrication minimizes wear, achieving a validated service life of 15,000 hours.
BoyinDrive drives innovation through structural design. Its proprietary W Tooth Profile achieves a mesh engagement ratio of over 40%. The flexspline thin-wall structure achieves an ultra-low failure rate of 1 ppm under test conditions and boosts torsional rigidity by 50%. Tooth lead modification ensures uniform-strength meshing across the full tooth width, while newly developed cross-roller bearings increase tilting stiffness by 30%–100%. The exhibited product series—YCS, YHS, YHD, and YCD—are engineered for rigorous operating conditions, helping OEMs simplify joint design and shorten development cycles.
The booth featured a prototype robotic arm from Jicui Intelligent Manufacturing, equipped with BoyinDrive harmonic drives, offering a tangible demonstration of component-to-system integration. Beyond standardized hardware, BoyinDrive provides full-lifecycle technical support, assisting customers in optimizing applications and navigating product iteration and market challenges.
Stable, scalable delivery is backed by a robust smart manufacturing and quality control system. BoyinDrive utilizes high-precision machining, automated production lines, data-driven process iteration, intelligent in-line inspection, and automated assembly to guarantee batch consistency.
During the exhibition, the BoyinDrive team engaged with numerous professionals on product selection, durability validation, custom development, and supply chain localization.
As humanoid robots and high-end automation accelerate toward industrialization, self-reliance in core components is critical. BoyinDrive will continue to make breakthroughs in precision harmonic transmission technology, promoting collaborative innovation in materials, precision machining, and drive control. The company remains committed to expanding application scenarios and providing downstream OEMs with reliable precision transmission solutions.
