Abstract: ［Objective］To address the issues of high VOC emissions，high energy consumption， and low production efficiency associated with traditional two-station roof painting processes（basecoat + clearcoat）.［Methods］This study introduces a new black lacquer tinting material and systematically sorts out，implements import schemes，and optimizes on-site construction processes to achieve theeffect of replacing the original two-station spraying process with a single-station spraying process.Meanwhile，focusing on the black lacquer tinting process，from matching performance testing，on-site adaptive equipment modification，appearance color adjustment，to surface defect grinding and polishing treatment，as well as abnormal issue handling，a complete set of technical solutions has been developed.［Results］This process technology has successfully achieved stable switching and feeding，significantly reducing VOC emissions and energy consumption，improving production efficiency，while optimizing body appearance quality and enhancing product market competitiveness.［Conclusion］ This study proposes targeted solutions，providing practical references and ideas for the optimization and upgradingof automotive coating processes.
