From large products to small processed items, anodizing treatment (hard and general).
Both large and small processed products can be delivered in a short time. Please consult us regarding general and hard anodizing.
From September 16 to 17, we exhibited at the "Gunma Tech EXPO 2026." Thank you for the various inquiries we received afterward. Next, we will be exhibiting at the "Tsubame Sanjo Monozukuri Messe 2026." Anodizing tank: 1,500mm × 800mm × 3,000mm Maximum compatible size: 2,700mm × 650mm × 1,250mm Maximum weight: up to 400kg We respond to large lots and small lots of various products with short delivery times. By utilizing the size of the anodizing electrolytic tank to anodize as many products as possible simultaneously, we contribute to reducing individual costs. Since we perform anodizing treatments on complex shapes and combinations of different alloys, we also provide masking services. This helps eliminate the hassle of reprocessing after anodizing. "Hard anodizing" is highly regarded for its hard and thick coating, which provides excellent "corrosion resistance," "electrical insulation," and "heat resistance," among other applications.
