10th China Automotive Corrosion, Aging & Fastening Joining Conference 2025
The "10th China Automotive Corrosion, Aging & Fastening Joining Conference 2025" concluded successfully on December 11, 2025, in Chongqing. As a leading innovator in surface treatment solutions for automotive fasteners, Changzhou Junhe Technology delivered a keynote presentation titled "Digital Intelligence Empowering the Coating Industry."Building on the widespread attention it has garnered at numerous industry conferences and exhibitions, Junhe further presented a comprehensive overview at this event of its pioneering coating equipment and integrated digital-intelligent coating production lines, highlighting their value and strategic significance. The presentation received strong recognition and interest from industry experts, OEM representatives, and supply chain partners.
Industry-First Equipment Unveiled, Pioneering a New Paradigm in Fastener Coating
The Necessity of Launching Digital-Intelligent Coating Lines: Industrial Upgrading Is Inevitable
In its keynote presentation, Junhe’s technical team emphasized that with the accelerating trends of vehicle lightweighting and electrification, the number of fasteners is increasing significantly, along with heightened demands for reliability. Meanwhile, OEMs are imposing stricter requirements on traceability and consistency throughout the coating process—challenges that traditional coating methods can no longer address within future quality management frameworks.
The introduction of digital-intelligent coating lines has thus become an inevitable response to the industry’s evolution, primarily driven by the following needs:
1. Demand for Higher Quality Consistency: Traditional, experience-based manual processes cannot reliably ensure consistent film thickness, uniformity, or performance output.
2. Requirement for Transparent and Traceable Processes: OEMs now expect real-time access to coating parameters, batch histories, and anomaly logs—demanding full "visibility and control" over the entire process.
3. Urgent Need for Cost Reduction and Efficiency Gains: Rising costs in energy, labor, and facility space compel manufacturers to adopt digital-intelligent solutions to optimize resource utilization and productivity.
4. Need for Flexible Manufacturing: With the vast variety of fasteners requiring frequent production switches, conventional systems suffer from slow changeovers and high error rates.
Consequently, integrating process know-how, advanced equipment, intelligent logistics, and data systems into a unified digital-intelligent coating line has emerged as a critical strategic direction for the surface treatment of automotive components.
Junhe Unveils Four Key Features of Its Digital-Intelligent Coating Line—Receiving Enthusiastic Response Onsite
At the conference, Junhe spotlighted the four core features of its integrated digital-intelligent coating line—delivering a systematic upgrade across the entire value chain, from equipment and process engineering to on-site operations and data management. The key highlights include:
① End-to-End Automation & Equipment Synergy
The line seamlessly integrates modular units—including cleaning, shot blasting, coating, curing, inspection, and packaging—connected via standardized interfaces and a centralized scheduling system. This enables:
Automatic material transfer and line switching
Real-time dispatching of process instructions
Continuous equipment status monitoring and end-to-end early-warning alerts
Collectively, these capabilities help manufacturers optimize production takt time and significantly reduce labor costs.
② Digital Visualization & Full Quality Traceability
Built on an integrated MES and industrial control architecture, the system establishes a transparent process control framework that precisely meets OEMs’ stringent supply chain requirements. It captures coating parameters in real time and manages batches, work orders, and process recipes online. The platform supports root-cause analysis of anomalies and visualizes quality trends—fully fulfilling the industry’s “traceable and controllable” mandate.
③ Flexible Architecture for Multi-Variant Fastener Production
Addressing the automotive industry’s pain points—small batch sizes, high part variety, and frequent changeovers—the line features a modular, plug-and-play structure with rapid changeover mechanisms and anti-mixing safeguards. Coupled with flexible logistics routing (including AGV and automated storage integration), it dramatically shortens changeover time, minimizes material mix-up risks, and greatly enhances production flexibility and adaptability.
④ Green & Intelligent Manufacturing
The line embodies a low-carbon, energy-efficient process chain. Through precision control and intelligent energy management, it achieves over 30% higher energy efficiency compared to conventional coating lines. While maintaining high productivity, it actively fulfills environmental responsibilities—setting a new benchmark for sustainable, intelligent manufacturing in the fastener surface treatment industry.
The comprehensive solution drew strong interest and acclaim from attendees, affirming Junhe’s leadership in driving the digital transformation of automotive fastener coating.
Following the presentation, multiple OEMs and leading automotive component manufacturers engaged in in-depth discussions with Junhe, exploring potential collaborations in areas such as joint project development, smart factory upgrades, and enhanced coating quality.
Industry experts at the event remarked that Junhe’s pioneering equipment and digital-intelligent coating line have introduced a fresh perspective to the sector, offering significant value in improving the reliability of fastening systems and boosting production efficiency.
