The sauce is generated not only by the skill of the operator but also by three conditions: film thickness, viscosity, and component posture.
Dripping defects are visual defects where the paint flows and leaves streaks. At customer sites, this can become an issue not only in terms of appearance but also as dimensional defects around holes and fitting areas. The cause is not solely the way the operator applies the paint. When three conditions—film thickness, viscosity, and component orientation—overlap, the paint tends to accumulate in one spot. Areas such as corners, downward surfaces, and around holes are particularly prone to dripping. Initially, we check the location of the drips, the direction of painting, how the jig is applied, and the drying time. Countermeasures include determining the discharge amount, gun distance, viscosity, jig orientation, and holding time before drying for each component. By documenting the locations of occurrence with photos or records, we can reflect on which shapes are prone to dripping in future productions. Reducing drips also helps prevent issues like hole filling and film thickness defects. Please utilize verification materials for reviewing painting conditions. Instead of stopping at operator training, reflecting the prone positions for dripping in standard documents for each component will make it easier to prevent recurrence in the next lot.
