Deep in the flexible joints of industrial robots, at the moment when service robots smoothly execute instructions, a precise "heart" silently supports every precise movement - that is, the robot joint reducer. Changzhou TiLi reducer Co., Ltd., located in Changzhou, Jiangsu, is quietly becoming an indispensable "joint power expert" for many well-known robot companies in China with its profound precision manufacturing expertise and forward-looking customization strategy.

Deeply cultivating precision and anchoring the core track of robots

TiLi reducers are not new recruits in the industry. With years of experience in precision gear design, material heat treatment, and advanced manufacturing processes in the field of industrial reducers, the company has keenly captured the huge demand for high-performance and high reliability joint reducers in the robotics industry and decisively tilted its strategic focus towards this high value-added field.

The joints of robots, especially collaborative robots, humanoid robots, and high-precision industrial robotic arms, have almost stringent requirements for the volume, weight, accuracy, rigidity, lifespan, and noise of reducers, "emphasized the technical director of TiLi." This is precisely the advantage of TiLi's technological accumulation. ”The company continues to invest in research and development, making breakthroughs in key technologies such as robot reducers, and mastering core processes such as high-precision tooth profile design, special material application, precision machining and assembly.

Customized Development: Tailored for Robot Enterprises

Different from the bulk supply of standard products, TiLi's core competitiveness lies in deep customized services. They deeply understand that there are significant differences in performance requirements for joint reducers among different robot manufacturers and application scenarios, such as precision assembly, conveying and handling, medical surgery, and consumer services.

Precise docking of requirements: TiLi establishes a joint development mechanism with robot customers to deeply communicate core indicators such as load, accuracy, size, dynamic response, lifespan, and cost from the initial stage of the project.

Flexible Design and Manufacturing: Relying on modular design platforms and flexible production lines, TiLi can quickly respond to customers' unique needs, adjust design parameters (such as reduction ratio, output flange, shaft diameter, sealing form), optimize internal structures, and even develop special material solutions.

Rapid iteration verification: A comprehensive prototype trial production and small batch verification process has been established to ensure that the design scheme can be quickly implemented and meet the stringent performance testing requirements of customers.

The technical director of a well-known domestic collaborative robot enterprise said, "Our cooperation with TiLi has solved our pain points. They not only provide gearboxes that meet performance indicators, but also customize ultra-thin harmonic gearboxes based on our compact design, significantly optimizing our product structure and performance. ”

Seize the opportunity: Seize the new trend of humanoid robots

Currently, the robotics industry is experiencing two strong trends:

On the eve of the outbreak of humanoid robots: the rapid iteration of Tesla Optimus, the collaboration between Figure 01 and OpenAI, and breakthroughs from domestic companies such as Ubiquitous have ignited the enthusiasm of the humanoid robot industry. The demand for miniaturized, lightweight, and high power density reducers in humanoid robots with dozens of joints throughout the body is growing exponentially. TiLi actively lays out its ultra small, high torque density reducer solution suitable for space limited areas such as finger joints, wrists, elbows, etc., which has attracted the attention and cooperation intention of multiple cutting-edge humanoid robot companies.

Domestic substitution acceleration: For a long time, the high-end robot gearbox market has been dominated by Japanese brands. With the maturity of the domestic robot industry chain and the increasing demand for independent controllability, domestic gearbox suppliers with reliable performance, rapid service response, and better cost-effectiveness have ushered in a historic opportunity. TiLi, with its customization capabilities and continuously improving quality control, is steadily entering the supply chain of more leading domestic robot companies and becoming an important force in the wave of "domestic substitution".

Building a foundation of quality and winning market trust

Customization does not mean compromising quality. TiLi is well aware that reliability is the lifeline of robot joints. The company has established a strict full process quality control system, from raw material entry to precision machining, heat treatment, finished product assembly, to final noise testing, life testing (ensuring a service life of generally over 8000 hours), precision testing, and dynamic performance testing. Each level of inspection ensures that every customized gearbox delivered can withstand the test of harsh working conditions.

Outlook: Empowering Domestic Robots to Take Off

The development of the robotics industry, especially humanoid robots, is a key part of China's high-end manufacturing transformation and upgrading. As a core basic component supplier, TiLi feels a great sense of responsibility and is full of confidence. ”The General Manager of TiLi reducer Co., Ltd. looks forward to continuing to focus on breakthroughs in core technologies, deepening customized service capabilities, and serving every robot partner with better performance, higher reliability, and faster response speed, jointly promoting the 'joints' of China's intelligent manufacturing to be more robust and flexible

Expert review:

In the field of core robot components, customization capability is one of the key paths for local enterprises to break through. Changzhou TiLi has precisely entered this track and demonstrated keen market insight. Its technological accumulation and rapid response mechanism meet the urgent needs of diversified and innovative development of domestic robots. Especially in the hot field of humanoid robots, whoever can provide joint solutions that meet the ultimate space and performance requirements will occupy a favorable position in the value chain. TiLi's practice provides valuable exploration for the independent controllability and upgrading of China's robot industry chain. ”Li Li (pseudonym), Senior Analyst at Gaogong Robotics Industry Research Institute
