Jiangsu Believe Presents High-Performance Rotary Shaft Seal Solutions at CIBF2025

On May 15, 2025, Shenzhen, China, the 17th China International Battery Technology Exchange Conference/Exhibition (CIBF2025) was grandly opened at the Shenzhen International Convention and Exhibition Center. As a technological innovator in the key links of the new energy industry chain, Jiangsu Believe Automation Technology Co.,Ltd. presented its independently developed "high-performance rotary shaft seal" low-speed horizontal equipment shaft end sealing solution at the exhibition, providing a new breakthrough path for the shaft end sealing problem in new energy material mixing equipment.

Directly hit the pain points of the industry to solve the stubborn problem of leakage in mixing equipment

In the mixing pretreatment of key raw materials such as positive and negative electrode materials and solid electrolytes of new energy batteries, traditional packing seals have long restricted production efficiency and material utilization due to problems such as easy wear, high leakage rate, and frequent maintenance. According to industry estimates, the average annual leakage loss of mixing equipment using old sealing technology can reach 3%-5%, and frequent shutdowns for maintenance have led to a drop in capacity utilization of more than 15%.

The high-performance rotary shaft seal solution launched by Jiangsu Believe controls the leakage rate below 0.03% through the innovative dynamic contact soft surface seal structure design, which is two orders of magnitude higher than the traditional technology. The internal seal is made of high-performance engineering plastics, which can adapt to extreme working conditions from -60℃ to 200℃. While ensuring zero leakage, the maintenance cycle is extended from the traditional 60 days to 15,000 hours, significantly reducing the company's comprehensive operation and maintenance costs.

Technical advantages verified by leading companies

At present, the technology has been verified on a large scale in a domestic TOP3 cathode material company. Actual production data shows that after applying Believe rotary shaft seals, the company's annual production of 50,000 tons of high-nickel ternary materials production line reduces material loss by more than 280 tons/year, the overall equipment efficiency (OEE) increases by 19%, and the annual cost savings of a single production line exceed 6 million yuan.

The breakthrough in sealing technology is not only about cost control, but also directly affects the uniformity of material mixing and batch consistency. Mr. Yuan, chief engineer of Jiangsu Believe, said at the exhibition: "Our solution has achieved full compatibility with domestic and international mainstream mixing equipment. In the future, we will work with equipment manufacturers to promote the intelligent upgrade of new energy material preparation."

Jiangsu Believe will hold a rotary shaft seal product exchange meeting at booth 8T028 in Hall 8 of the exhibition at 10:00 am on May 15, deeply analyzing the application practice of rotary shaft seals in cutting-edge fields such as new energy battery raw materials.
