Wuxi Zejia successfully won the bid for the high-end coupling project of China Second Heavy Industries Equipment
Technological breakthroughs lead the industry standards
The couplings won in this bid will be applied to the latest 3000-millimeter titanium plate rolling production line developed by Second Heavy Industries Equipment. This production line is the largest-sized dedicated titanium plate rolling equipment independently designed in China, which is crucial for the precision and rigidity of the supporting components
And the requirements for stability are extremely strict. The SWF type split head cross shaft universal coupling provided by Zejia Technology is made of ultra-high strength alloy steel and achieves a dynamic transmission error of ±0.05 millimeters through an innovative structural design
The control perfectly meets the working condition requirements of high-frequency reversing loads during the titanium plate rolling process.
It is worth noting that the technology of this type of coupling originated from the national standard project (project number TC109) led by Second Heavy Industries Equipment. As one of the core participating units, Zejia Technology’s technological level has entered the first echelon of the industry.
This successful bid further validates the feasibility of the enterprise’s collaborative innovation model of “process – equipment – materials”.
Deepen the layout in the high-end manufacturing sector
Public information shows that Wuxi Zejia has continuously increased its investment in research and development in recent years. In 2024, it has successively stood out in coupling bidding projects in places such as Ziyang, Sichuan Province and Hefei, Anhui Province. The enterprise has developed its own intelligent monitoring system
The system has achieved real-time data collection of the operating status of couplings and fault early warning. This technology has become a key plus point in the bidding of the Second Heavy Industry project this time.
The project leader of the Second Heavy Industries Equipment project stated: “The products of Zejia Technology have demonstrated outstanding reliability in extreme load tests, and its technical solution holds strategic significance for enhancing the independent controllability of China’s titanium alloy equipment industry chain.” “
According to the plan, the first batch of couplings will be delivered by the end of September 2024 to ensure the construction progress of major national equipment projects.
Industry impact and Future outlook
This cooperation not only consolidated Zejia Technology’s market position in the field of heavy machinery accessories, but also promoted the large-scale application of domestic high-end couplings in aerospace, Marine engineering and other fields.
With the in-depth advancement of the “Made in China 2024” strategy, the process of domestic substitution of core basic components is expected to accelerate further. The general manager of Zejia Technology disclosed in an interview that the company is collaborating with multiple research institutions to tackle new challenges
The next-generation intelligent coupling technology is expected to launch a revolutionary product with integrated wireless sensing function in 2026.
