Our “hardened chrome plating” is based on the “Method of Applying Hard Metallic Chrome” patented by our founder Minoru Araki, and we have made progress in research and development while making use of our experience in the fields of application that are constantly advancing.
It can be finished to a maximum roughness of 30nm (0.03μm) or less.
Cylindricity, roundness, and runout can be processed to 3μm or less.
Our unique pre-treatment method allows us to process highly adhesive chrome plating on to aluminum rolls.
