Suzhou Tongjin Precision Industrial Co., Ltd. – Company Profile
Suzhou Tongjin Precision Industrial Co., Ltd. was established in December 2002. It is currently headquartered at No. 411 Jianlin Road, Suzhou High-tech Industrial Development Zone, with a registered capital of 45.36 million yuan. The company underwent a shareholding reform in September 2015 and was listed on the National Equities Exchange and Quotations (NEEQ) on May 18, 2016, under the stock code 837453. It currently employs nearly 300 staff members, including over 100 personnel dedicated to research and development. The company currently possesses modern office and factory facilities covering approximately 20,000 square meters. Shenzhen Tongjin Intelligent Technology Co., Ltd., established in June 2022, is located at Room 814, Building C, Innovation Plaza, No. 2007 Pingshan Avenue, Pingshan District, Shenzhen; it is a Shenzhen branch of Suzhou Tongjin.
For many years, the company has upheld the vision of "achieving green, unmanned manufacturing in its factories"; the mission of "connecting with the world, creating a splendid China"; and the core corporate values of "innovation, enterprise, integrity, and harmony." Building upon the introduction of cutting-edge foreign automated core components, the company has made substantial investments in research and development. Focusing on industries such as new energy vehicles, humanoid robots, 5G, aerospace, energy storage batteries, photovoltaics, and entertainment stages, the company addresses the technical requirements for intelligent servo automation systems. It has successfully independently developed, designed, assembled, and marketed its proprietary products, including Tongjin-brand servo electric cylinders, intelligent servo assembly machines, seventh-axis robots, and (heavy-duty) truss robots. By integrating these systems with six-joint robots, the company has realized intelligent, automated, and unmanned green assembly production lines, providing one-stop integrated solutions for intelligent assembly automation systems in manufacturing facilities. Meanwhile,Suzhou Tongjin's products are exported to nearly 30 countries worldwide. The company remains committed to technological innovation, adheres to international quality standards, and leverages its precision intelligent equipment to drive high-quality development in the global manufacturing sector.
In recent years, Tongjin has consistently prioritized research and development investment, while actively expanding its efforts in talent recruitment and internal talent development. The company has applied for over 200 patents, of which 112 have been granted—comprising 54 invention patents, 1 design patent, and 55 utility model patents. Additionally, the company has secured 17 software copyright registrations, 6 software product certifications, 5 Jiangsu Provincial High-Tech Product designations, 5 trademark registrations, 6 international PCT applications, 1 national standard, 1 industry association standard, and 16 corporate standards.
Centering on its four business units (BUs), the company has established a comprehensive product and service ecosystem spanning from core components to intelligent production lines:
I. Servo Cylinder BU
Our product line spans from miniature thumb actuators (5 kg) to heavy-duty servo electric cylinders with capacities up to 500 tons, providing flexible and reliable motion actuation components for humanoid robots and high-precision industrial applications.
II. Servo Press BU
Focusing on servo press-fitting technology and precision assembly processes, we provide intelligent press-fitting equipment, unmanned production line solutions, as well as vision AI algorithm-guided inspection, enabling high precision, traceability, automation, and intelligence throughout the assembly process.
Building upon the seventh-axis robot and the heavy-duty truss robot, and integrating a six-joint robot along with visual AI algorithms for guidance and detection, we are developing flexible processing and automated manufacturing systems as well as digital twins, enabling factories to achieve safe, green, and efficient intelligent production.
IV. New Energy Business Unit
Focusing on production lines for servo motors, new energy vehicle motors, and humanoid robot joint modules (frameless motors), we leverage AI algorithms to provide core components and comprehensive, flexible, and customized production solutions for the new energy and robotics sectors.
Through the synergy of its four core business areas, Suzhou Tongjin has acquired comprehensive capabilities—from proprietary product R&D to one-stop intelligent assembly system integration—thereby continuously driving the transformation and upgrading of the manufacturing sector toward automation, digitalization, and green development.
