Is 70% of foreign matter contamination brought in by 'people'? Dust prevention measures in painting booths.
Even after replacing the filter, the debris doesn't decrease. The truth about work clothes and the attraction of foreign objects due to static electricity, which tends to be overlooked.
[Cause of Occurrence] One of the top causes of poor painting quality is "foreign matter contamination (dust and particles)" on the paint film. Many factories try to address this by increasing the frequency of replacing the intake and exhaust filters in the painting booth, but it is not uncommon for the expected results to not be achieved. [Truth] In fact, about 70% of the dust that adheres to the painted surface is caused by the workers' own "work clothes (dust generation)" and "static electricity" from parts brought in. Especially in winter, static electricity tends to occur, attracting fine dust in the air to the parts like a magnet, leading to frequent defects such as pinholes. [Improvement Measures] It is essential to ensure proper static elimination (installation of ionizers), thorough air showers before entering the booth, and wearing low-dust clean suits. A manual for dust prevention and static elimination measures to dramatically reduce foreign matter contamination can be downloaded for free from here. [Summary] The fundamental countermeasure against foreign matter contamination is not just the replacement of equipment filters, but also preventing dust generation from workers and implementing thorough static electricity measures. Eiwa Kogei Co., Ltd. conducts high-quality painting with foreign matter contamination minimized to the extreme under strict dust and static management.

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.
