I want a uniform and well-adhering insulating film, but the corners and recessed areas become thin. This explains the causes of thickness variation that lead to weaknesses in insulation and offers tips on application methods.
I want to apply an insulating coating to electrical components, but the thickness varies by location. The corners and the depths of holes are thin, and I’m worried whether the insulation will be sufficient. 【First, please look here】 □ The coating on corners and edges is thin → Paint tends to escape from corners, resulting in a thinner coating. □ The depths of dents and holes are thin → With electrostatic spraying, it becomes difficult for the paint to reach the depths. □ The thickness on flat surfaces also varies → The hanging method and spraying direction are not consistent. 【Why this is a problem】 The performance of the insulation is determined by the thinnest area. Even if the flat surfaces have sufficient thickness, if the corners are thin, that becomes a weak point. 【Countermeasures you can take starting today】 1. Always include corners and depths when measuring coating thickness. 2. Chamfer the corners to create a shape that allows the paint to adhere better. 3. Decide on the hanging method and direction, and verify the distribution of coating thickness with prototypes. 【Free materials】 We have compiled the details of our oven curing and powder coating services in the related catalog "Oven Curing Service."

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.
