■Feb 2019. We are pleased to announce that we now have the English Website Page about TOEI-denka kougyou.
Anodizing process of high functionally on aluminum.
Open up new possibilities, with our technology of aluminum.
Quality management system standard
Environmental management system standard
Over the years, Our product is used in numerous optical precision parts manufacturers.
We are proud that matte black anodized aluminum with little color unevenness and high dimensional accuracy is the best in technology and quality in Japan.
Especially, "Finish Zero" the surface treatment technology accumulated for more than 40 years is ideal for precision equipment parts such as camera, sensor, light source apparatus and inspection equipment due to it’s less amount of dimensional change.
Palcoat (3700 and 3762) is compliant with the environmental regulation in EU (RoHS and ELV). It is optimal for switching from hexavalent chromium containing treatment. Palcoat obtain high corrosion resistance of MIL spec.
We have a wide variation of dyes, and by preparing various dyes, the color variation is infinite.
Our color anodized aluminum is different from others. We have a track record of multicolor color anodized aluminum in various fields such as wearable products and sporting goods.
We uniquely developed hoop part gold plating equipment, and it realize high speed processing and cost reduction of plating.
Our equipment also supports mass production of nickel barrier plating for narrow pitch connectors. Furthermore, we are making standardized hoop lines and it possible to realize multifarious small quantity production with short delivery time.
