With the rational refinement of aluminium and stainless steel we have dedicated ourselves entirely to the barrel finish. We have invested even more time and know-how in the further development of these special processes. Where in classic anodic oxidation/anodising and electropolishing all parts are placed individually by hand on conductive frames, customers lost valuable time. This is neither practicable nor economical for small parts for cost reasons. The Stalder team relies on specific finishing in the barrel. With these processes, small parts such as rivets, nipples, screws, nuts, bolts or turned parts can be processed in large quantities with guaranteed economic efficiency. Bulk material enters the drum already during pre-treatment and passes through the most efficient process up to finishing. In this way, hundreds of thousands of parts can be finished every day. Additional modules for further process steps offer a whole range of solutions. Individual customer requirements can be taken into account. You decide whether your smallestparts are treated in colour or with a special function.
