Tomisho's hard anodized aluminum

Since inheriting the patent of "New hard aluminum oxide coating method“ from Nippon Light Metal Co., Ltd. in 1965, our technology has been getting a large evaluation in a usage that corrosion resistance, electrical insulation properties, and heatproof, etc. by the hard and thick coat, because it is different from the coating which is only thick anodized aluminum.

新硬質皮膜法

The secret of generating our unparalleled thick and minute coating is the management for the liquid temperature as 5℃ in the electrolysis tank by freezer with the heat exchangeability of 110,000Kcal. If the holes of coated products are not sealed, a thick coat is applied also to the products that focus on oil impregnation because an excellent feature as the impregnation is demonstrated.
