Washing / pickling passivation
Aluminium alloy castings, extrusions and sheet are cleaned here; a conversion coating is applied to prepare the parts for subsequent joining processes. Thanks to its size and speed of operation, Hanomag Aluminium Solutions’s fully automated and NC-controlled unit for washing, pickling and passivation offers manifold options and is suitable for huge production volumes. It has eight dip tanks, each with a capacity of 10 m3, and this allows component-specific surface treatments to be carried out continuously.
This unit allows small or very large quantities of light-metal components up to 2,000 mm long to be prepared for subsequent physico-chemical treatment.
