Understanding the mechanism of occurrence can prevent recurrence.
Are you troubled by pinholes that create small holes in the painted surface? Even if they appear minor, they can often lead to quality issues. Many of the causes are due to solvents in the paint evaporating rapidly or gases emanating from the substrate. Particularly, thick applications and deviations in drying conditions can easily trap air bubbles inside. Additionally, the frequency of occurrence can vary significantly depending on the type of material and the state of pretreatment. As a countermeasure, managing film thickness and optimizing the drying process are crucial. So, why do pinholes occur sometimes even under the same conditions? Paint defects cannot be improved with a vague approach. Accurately identifying the cause is the first step in preventing recurrence. Our company has published materials summarizing case studies on improving paint defects, including pinholes. Please take a moment to review them to avoid repeating the same issues.

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.
