China's first active suspension actuator smart assembly line with fully independent intellectual property — led by CIJAN and built with Zhongke Motong (Changzhou) Intelligent Manufacturing Co., Ltd. — has passed comprehensive acceptance. The equipment has been packed and shipped to CIJAN's production base and is about to enter operation. The delivery fills a domestic gap in mass-production equipment for high-end active suspension core components, laying a smart-manufacturing foundation for large-scale production of homegrown intelligent chassis parts.

A Key Step Toward Self-Reliance in Active Suspension Actuators

The active suspension actuator is a core precision component of intelligent chassis and electronically controlled suspension, directly determining ride comfort, handling stability, and ADAS compatibility. A long-time leader in China's shock absorber industry, CIJAN has built a core product matrix covering ADS, ECAS, and FAS. The new assembly line marks a key step toward independent mass production of intelligent suspension core components.

High-precision actuator assembly, in-line inspection, and full-process digital production lines have long relied on imported turnkey equipment — costly to procure and maintain, and restrictive for process customization and technology iteration. The jointly developed line, China's first of its kind with independent IP, addresses this challenge.

Full Independent IP, Tackling Industry Pain Points

Drawing on years of expertise in smart manufacturing for chassis components, Zhongke Motong's team independently delivered the overall line design, mechanical development, control-system programming, vision-based positioning and inspection, and data-traceability platform — the complete software and hardware stack is fully homegrown, eliminating external technological dependence.

During development, the team conducted simulation iterations and workstation joint commissioning, overcoming micron-level assembly alignment, multi-process synchronization, and batch consistency control. The delivered line achieves fully automated operation across all processes, laying a solid foundation for CIJAN's large-scale mass production of intelligent suspension core components.

All Indicators Exceed Contractual Standards, Independent Line Drives Quality Breakthrough

CIJAN's acceptance experts verified every assessment item against the technical agreement and industry standards — workstation precision, repeat assembly consistency, inspection pass rate, no-load and loaded stability, safety systems, and digital integration. All measured indicators exceeded contractual requirements, and the line passed final acceptance at the first attempt.

Once in operation, the line will significantly reduce labor input, stabilize yield, shorten the ramp-up cycle for new products, and resolve long-standing issues such as slow after-sales response and limited customization.

Supporting a Self-Reliant Chinese Automotive Supply Chain

With 75 years of technical heritage, CIJAN has always placed intelligent manufacturing and core-technology self-reliance at the heart of its strategy. This delivery marks another milestone in its full value chain layout for intelligent suspension. Going forward, CIJAN will continue advancing R&D and smart manufacturing of core components — including intelligent suspension and shock absorbers — delivering reliable, secure, end-to-end intelligent suspension solutions that empower the self-reliance and high-quality transformation and upgrading of China's automotive industry.
