• Bulk anodized in drums

Stalder Swiss Finish offers the most efficient finishing of small parts with anodising of aluminium. Very small parts are quickly anodised in colour or colourlessly in barrels, whether in mid-sized runs or large-scale production. Stadler AG is thus the leader in Europe when it comes to barrel anodising.

This is how it works!
