For those struggling with plating processes, we are confident in our "quality and reliable transactions"!
Black dyeing chemical treatment is a chemical treatment method that involves immersing steel in an alkaline solution to create a ferric oxide film on its surface, resulting in a black appearance. Additionally, there is almost no dimensional change after treatment (about 1 micron), making it suitable for products with strict dimensional tolerances. The Asahi Plating black dyeing chemical treatment division focuses on maintaining and improving quality. For more details, please contact us or refer to the catalog.
