THE BLACKFAST PROCESS

Processing entails degreasing, conditioning or pickling if hardened steel, before immersing components in a blacking bath at room temperature. Corrosion protection is afforded by a final immersion in dewatering oil.

The process equipment required is a simple arrangement of polythene tanks and water rinses and does not require expensive extraction equipment. The process has been designed to be easily incorporated within most tooling and machinery manufacturing production lines.
