Measures for Defects in Coating Thickness of Metal Powder Coating
Defects in the film thickness of metal baked coatings are a cause of quality deterioration. This explains the importance of film thickness management and points for improvement.
In metal baking paint, the film thickness greatly affects product quality. If it is too thin, corrosion resistance and durability decrease, and if it is too thick, it can cause runs, dimensional defects, and assembly issues. Film thickness issues are influenced not only by the discharge amount and painting speed of the gun but also by paint viscosity, thinner dilution ratio, spraying distance, and product shape. In complex shapes, the film thickness tends to vary at corners and bag-like areas. Measuring with a film thickness gauge, managing viscosity, and standardizing discharge conditions are shortcuts to stabilizing quality.

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.
