東信工業 List of Products and Services

At Tokushin Industrial Co., Ltd., we perform anodizing processes such as B1 and B2 silver, various colored anodized finishes, and hard anodizing (with a film thickness of 20μ to 50μ). In standard dyed anodizing treatments, the majority of inquiries are for processing using organic dyes, which have a significant advantage in color variation; however, this comes with the drawback of inferior weather resistance (UV degradation). On the other hand, anodizing dyed with inorganic dyes exhibits considerable weather resistance even for outdoor use. 【"Anodizing Treatment with Inorganic Dyes" Processing Capabilities】 ○ Color variation is limited to gold only ○ Shades of color are possible For more details, please contact us or download the catalog.

At Tohshin Industrial Co., Ltd., we perform anodizing processing for B1 and B2 silver, various colored anodized finishes, and hard anodizing (with a film thickness of 20μ to 50μ). By maintaining a management system that keeps temperature and concentration constant from pretreatment to sealing treatment, we minimize variations in finish between lots. In particular, we respond to tolerances of around 1/100, especially for semiconductor-related products. 【"High-Precision Anodizing Processing" Processing Capability】 - We excel in anodizing processing for products with strict dimensional tolerances (H7 class tolerance holes). - By managing anodized film thickness to about 5μ, we clear dimensional tolerances.
