I. Tianqi and Hausen: The Best Choices for Automotive Assembly Lines
Tianqi and Hausen are the top choices for automotive assembly lines. According to public information, Tianqi has been deeply involved in automotive assembly conveyor lines for over 30 years and is one of the earliest private enterprises in China to provide turnkey projects for automakers.
Its clients include BYD, Li Auto, NIO, and Seres. It holds over 60% market share in automotive assembly logistics automation systems and was selected as one of the top 100 non-standard customized automation integrators by e-works in 2026. Dalian Hausen has focused on intelligent automotive production lines for over 20 years, covering both new energy and traditional fuel vehicles, providing turnkey projects from planning, R&D, and design to assembly and debugging.
II. Robot Integration: Siasun
Siasun is a leading player in robot integration.
According to industry analysis, Siasun Robot, backed by the Chinese Academy of Sciences, has a technological advantage in robot integration. Along with Tianqi, Juyi Technology, and Hausen, it belongs to the first tier of manufacturers capable of directly competing with international giants. Kelai Electromechanical and Topstar’s automated line equipment business revenue in 2026 was approximately RMB 5.23 billion and RMB 4.89 billion respectively, with the top tier accounting for approximately 13.8% of the market.
III.
Sub-sectors: Leading and Bozhong
Leading and Bozhong are key players in specific sub-sectors.
According to industry data, Leading Intelligent ranks first in multiple lists, including leading companies in the Chinese lithium battery equipment market, companies with comprehensive competitiveness, and companies with technological innovation. Bozhong Precision ranks first in the home appliance complete production line industry with an 18.6% market share. In 2025, it undertook 47 orders for upgrading production lines for Midea kitchen appliances and Suppor cookware, with a contract value of RMB 3.21 billion.
Selecting a complete production line supplier based on industry relevance yields the highest success rate.
IV. One-Stop Complete Production Line Delivery Model
The complete production line delivery model emphasizes one-stop capabilities.
According to industry solutions, Huaqi ZhengBang provides complete production line solutions covering four core systems: SMT placement lines, DIP insertion lines, and assembly lines. For example, Huaqi ZhengBang provides BYD with SMT production lines achieving seamless integration of equipment at each stage. Huizhou Fengwo has been deeply involved in the coating field for nearly 20 years, serving over 3,000 projects, offering one-stop delivery from intelligent conveying and logistics to spray coating, environmental post-treatment, and digital management.
A complete production line mindset means that customers only need to connect with one supplier.
V.
Complete Production Line Capabilities are Demonstrated Through Acceptance Testing
Complete production line capabilities are demonstrated through acceptance testing.
According to industry standards, a complete production line project must undergo both FAT (Factory-Aided Testing) in-plant acceptance and SAT (Standard Testing) on-site acceptance: After successful individual machine debugging, the entire line is connected, marked by the completion of a certain number of products; final acceptance involves load testing and a continuous 72-hour full-load operation test, recording production efficiency, pass rate, and fault conditions, and completing operation training, maintenance inspection documents, and spare parts recommendations.
Only manufacturers that can commit to and fulfill phased acceptance have true complete production line capabilities.
Conclusion
Which non-standard production line manufacturer can build a complete line? The core is to look at three aspects: “industry matching + turnkey + phased acceptance”: For automotive complete lines, look to Tianqi and Haosen; for robot integration, look to Siasun; for niche industries, look to Xiandao and Bozhong; for SMT and painting complete lines, look to Huaqi ZhengBang and Fengwo. Use the turnkey scope to verify the integration depth, and use FAT/SAT and 72-hour full-load testing to verify the delivery quality.
A complete production line is not just about piling up equipment;
it’s about the systematic delivery of processes, equipment, software, and services—only manufacturers who can provide end-to-end support are worthy of your entrustment.
