en.Wedoany.com Reported - On May 13, 2026, Leetx, a Chinese automatic tightening and servo press-fitting company, together with Centron, a precision dispensing company, launched a series of tightening systems, press-fitting, and dispensing new products for battery PACK intelligent assembly at CIBF 2026, the 18th China International Battery Technology Conference/Exhibition, held at the Shenzhen World Exhibition & Convention Center.
According to data from the China Automotive Power Battery Industry Innovation Alliance, China's total shipments of power and energy storage batteries maintained a global lead in 2025, but imported brands hold a high share in high-precision tightening systems for the PACK intelligent assembly segment. With the new EU Battery Regulation and the demand for digitalization of domestic production lines, Chinese equipment manufacturers are gaining market opportunities.
Leetx showcased a complete product family including automatic screw feeding systems, electric screwdrivers, tightening wrenches, fixed tightening spindles, wireless tightening guns, and multi-axis synchronous tightening systems. Its launched three-axis synchronous screw feeding and tightening system has already been applied in batches at leading Chinese battery companies, achieving synchronous fastening of three bolts and increasing the single-station cycle time by over 50%. The multi-axis servo synchronous tightening system can be expanded to 20-axis synchronous tightening, achieving full closed-loop torque control, covering critical connections from battery packs to chassis subframes.
Centron's high-precision potting system uses 20L supply with stirring, vacuum degassing, screw metering, and suck-back valve glue control, precisely adapting to 3mm narrow-gap potting. Centron also launched the CS3000 intelligent modular control system, enabling plug-and-play for units such as supply, metering, vision, and central control, shortening the production line expansion cycle by 60%, and seamlessly integrating with existing CS2000 equipment.
Currently, Leetx and Centron have provided equipment and complete line services to dozens of Chinese vehicle manufacturers and battery system integrators, deploying thousands of core equipment sets, and have delivered projects to Europe, Southeast Asia, and North America. "We hope to show the outside world that, from critical connections to precision fluid control, Chinese companies can now provide a complete set of solutions that are deliverable, traceable, and ready for global markets," said a Leetx representative.
