Process Engineer - Painting

Responsible for formulating painting process plans, including parameter design for the entire process of pre-treatment (wiping, flame treatment, plasma treatment), spraying, and baking. Debug and optimize robot spraying trajectories, atomization pressure, fan width, flow rate, and other parameters to ensure film thickness uniformity. Analyze and resolve appearance defects during the painting process, such as sagging, orange peel, particles, craters, and color differences. Responsible for the testing and application of new paint materials, as well as process verification for color mixing. Monitor and maintain the process status of spray booths (temperature, humidity, cleanliness), paint supply and circulation systems, baking ovens, and other equipment. Prepare and maintain painting process parameter sheets, standard operating instructions, and other documents. Responsible for improving and optimizing coating performance (adhesion, abrasion resistance, weather resistance). Provide skills training to painting operators to ensure compliance with process specifications.
