| Title | Efficiency Comparison of Automotive Body Refinishing Using UV-Curable and Conventional Refinish Coatings | ||
| Keyword | |||
| Abstract | This study aims to investigate the differences in repair efficiency and quality performance between ultraviolet (UV)-curable coatings and conventional refinishing methods in automotive body repair. Six steel panels were used as test specimens to simulate scratch damage under three different color conditions. The repair procedures were conducted in accordance with the six standard operating processes of the Toyota body and paint refinishing system, using both UV-curable coating systems and conventional refinishing techniques. During the experiment, on-site observations and records were employed to compare the actual processing time required for each stage of the repair procedures. Meanwhile, repair quality was evaluated based on gloss level, surface flatness, and overall visual appearance, in order to assess the practical performance of both methods. The results indicate that, in terms of repair quality, the differences between the two methods in gloss, surface flatness, and overall visual appearance were within 1%, demonstrating comparable restoration performance. However, significant differences were observed in operational efficiency. The total processing time for conventional refinishing was approximately 180 minutes, whereas the UV-curable system required only about 58 minutes, resulting in a time reduction of 122 minutes and an overall efficiency improvement of 67.8%. In conclusion, UV-curable coating technology shows clear advantages in reducing curing time, simplifying operational procedures, and improving application efficiency. It not only enhances repair productivity but also contributes to reducing maintenance time and operational costs. The findings of this study provide a practical reference for process optimization, technology adoption, and maintenance management in automotive body repair, and demonstrate substantial value in improving service efficiency and quality within the industry. |
