Measures against pinholes in metal baked coatings.
Pinholes that occur in metal baked coatings. This will clearly explain the relationship with internal gases and pre-treatment.
Pinholes that occur in metal baked coatings are a typical defect where small holes appear on the surface of the paint film. The causes can be not only related to the painting process but also hidden within the gases inside the material or in the pretreatment process. In aluminum die-casting and castings, fine gases remaining from the manufacturing process can expand during baking and break through the paint film. Additionally, the residual oil and moisture can similarly lead to pinholes. Gas release through preheating, degreasing, and reviewing drying conditions are key 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.
