Shenzhen May 13, 2026 /PRNewswire/ — With the in-depth implementation of the “Digital Transformation Implementation Plan for the Automotive Industry” and related industrial plans for the “15th Five-Year Plan,” China’s power battery industry is accelerating its shift from “scale expansion” to a high-quality, high-consistency, and traceable digital and intelligent stage. Against this backdrop, Leetx, a leading domestic enterprise in automatic tightening and servo pressing, together with its sister brand Centron (a leading supplier of precision dispensing), made a joint appearance at booth 10T051 in Hall 10 of the Shenzhen World Exhibition & Convention Center during the 18th China International Battery Fair (CIBF 2026) from May 13 to 15. Leveraging the synergy of three core processes—”tightening, pressing, and dispensing”—they unveiled a series of new products for intelligent battery PACK assembly.
Responding to Dual Changes in Policy and Industry: A Window of Opportunity for Domestic Substitution of Key Process Equipment
According to data from the China Automotive Power Battery Industry Innovation Alliance and public industry sources, China’s combined shipments of power and energy storage batteries continued to lead globally in 2025. However, in the areas of high-precision tightening systems, servo pressing, and precision dispensing/potting equipment for PACK assembly, imported brands have long held a significant market share.
With the implementation of the EU’s New Battery Regulation, which mandates full lifecycle data traceability for batteries, and as leading domestic battery companies accelerate the digitalization and intelligentization of their production lines, domestic equipment manufacturers with full-stack self-development capabilities and the ability to provide complete process data loops are gaining unprecedented market opportunities.
Synergy of Three Core Processes: From Single Tools to Full-Line Data Loops
At this year’s CIBF, Leetx showcased a complete family of automated tightening products, including automatic screw feeding systems, electric screwdrivers, torque wrenches, fixed tightening spindles, cordless tightening guns, and multi-axis synchronous tightening systems. Paired with core pressing equipment such as servo presses, these products enable multi-station critical connections and precision pressing for components ranging from module end plates and busbars to the lower enclosure.
1. Multi-Axis Synchronous Fastening: Overcoming Stress Imbalance and Cycle Time Bottlenecks in PACK Assembly
Battery PACKs require numerous screws around their perimeter and demand high cycle times. Traditional single-axis sequential tightening is not only less efficient but also prone to elastic interactions between adjacent bolts during fastening, leading to preload loss and difficulty in ensuring uniform stress across the joint surface.
To address this challenge, Leetx introduced a three-axis synchronous screw feeding and tightening system, which has already been deployed in batch applications at leading domestic battery companies. In live demonstrations, a robotic arm simultaneously carried three sets of screw feeding and tightening actuators, enabling synchronous fastening of three bolts and increasing single-station cycle time by over 50%. Furthermore, its multi-axis servo synchronous tightening system, based on standardized control modules, can be expanded to support up to 20 axes of synchronous tightening, achieving full closed-loop torque control. This technology systematically covers all critical connections across the vehicle, from battery packs to electric drive assemblies and chassis subframes, eliminating assembly errors at the source and providing a viable assembly solution for building “intelligent demonstration production lines.”
2. High-Precision Potting: Precisely Addressing Narrow-Gap Potting and Full-Chain Traceability Challenges
The potting process for new energy battery PACKs demands extremely high precision. Centron’s high-precision potting system fully replicates the precise chain from material supply to dispensing: a 20L supply system with agitation addresses filler sedimentation, a transfer system performs vacuum degassing, a screw metering system ensures linear, pulse-free output, and an end-mounted suck-back valve controls dispensing to achieve zero dripping and zero stringing, precisely adapting to 3mm narrow-gap potting.
This full-chain precision control not only significantly improves adhesive utilization but also fundamentally responds to the national call to enhance the full lifecycle quality traceability of key components in new energy vehicles.
3. CS3000 Control System: Building the “Digital and Intelligent Brain” for Production Line Upgrades
Centron’s new-generation CS3000 intelligent modular control system, launched at this exhibition, enables “plug-and-play” integration of standardized functional units such as material supply, metering, vision, and central control, reducing production line expansion cycles by 60%. More importantly, existing CS2000 equipment can be seamlessly integrated into the new system, achieving “zero waste” in enterprise technology upgrade investments. The system’s built-in anomaly self-diagnosis and prevention functions effectively reduce on-site deployment risks and downtime.
Driven by Data, Demonstrating Long-Term Enterprise Value
The collaboration between Leetx and Centron is not a simple product overlay but a “1+1>2” ecological synergy that unlocks the underlying logic of assembly. Driven by data, the two companies continue to reshape new benchmarks in intelligent assembly. Currently, Leetx and Centron have provided equipment and full-line services to dozens of mainstream domestic automakers and leading power battery and energy storage system integrators, deploying thousands of core equipment units and continuously delivering projects to overseas markets in Europe, Southeast Asia, and North America. Their product capabilities have passed rigorous process and compliance audits by multiple international clients.
“We want the world to see that Chinese companies can now provide a complete, deliverable, traceable, and export-ready solution, from critical connections to precision fluid control,” said a Leetx representative.
Against the backdrop of the accelerating restructuring of the global battery supply chain, the simultaneous international expansion of domestic high-end intelligent equipment, represented by Leetx and Centron, is becoming a key piece of the global competitiveness of China’s new energy industry chain. Facing the ever-changing market demands in the future, these enterprises that master core processes and digital-intelligent foundations will undoubtedly become a driving force in advancing China’s automotive industry toward high-end and intelligent development.
