Entry Section

Mitsubishi-Hitachi Metals Machinery, Inc. pre-cleaning systems utilize electrolysis and brush scrubbers to perform alkali cleaning of the strip prior to the annealing process. This cleans the strip surface and removes oil, steel particles, dirt, and other materials, improving plating adhesion.
Mitsubishi-Hitachi Metals Machinery, Inc. provides vertical-type, horizontal-type, and combination-type pre-cleaning systems according to customer requirements.
