Why consolidating everything from preprocessing to delivery under one company improves quality.
One window, all solutions. Comprehensive support from pre-processing to delivery.
Eihei Kogei handles the entire process in-house, including zinc phosphate treatment (in-house), baking paint, inspection, packaging, and delivery. When pre-treatment, painting, and logistics are managed separately, communication errors between contractors and variations in quality are more likely to occur. By consolidating points of contact, delivery management becomes dramatically simpler. Please feel free to consult us first. 【Integrated Response Flow】 - Stripping and cleaning (Group company PPC) - Zinc phosphate coating treatment (in-house) - Baking paint and powder coating - Quality inspection - Packaging and delivery (self-owned 2-ton trucks available for Osaka Hirano, Yao, and Higashi-Osaka)

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.
