Appearance defects caused by paint dripping occur due to excessive film thickness or irregularities in viscosity management.
The defect is an appearance issue where the paint flows on the coated surface, creating streaks. At the customer’s site, not only the appearance but also the dimensions and assembly can be problematic. The causes include excessive spraying, reduced viscosity, gun distance, posture before drying, and paint pooling due to the shape of the parts. Preventing recurrence can be achieved not only by the skill of the operator but also by standardizing the film thickness criteria, discharge amount, jig posture, and holding time.

Company information
We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
