Some of the sprayed paint does not adhere to the parts and is wasted. With paint being expensive now, we explain the technology introduced in industry publications that reduces overspray.
The price of paint has risen, and I want to reduce the amount used as much as possible. Don't you think that all the paint sprayed is sticking to the parts? 【What is happening now】 According to Paint News (October 7, 2026), Asahi Sunac has announced a new handgun and controller that suppresses overspray in electrostatic painting. It adjusts the voltage according to the movement of the gun, claiming to reduce overspray to workers by up to 80 percent. In the company's experiments, the amount of paint used was reduced by 24 percent for flat parts and 46 percent for frames. 【Situations where overspray increases】 □ Spraying from a position that is too close to the parts □ Spraying strongly at corners or recessed areas 【Countermeasures you can take starting today】 1. Record the amount of paint used per part 2. Review the spraying distance and air pressure 【Free Materials】 We have compiled the painting methods and equipment responses in the related catalog "What Eiwa Can Do for Metal Painting." You can download it for free from this page.

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.
