Tscherwitschke: 50 years of mechanically butt-welded electroplating drums

In 1974, Richard Tscherwitschke GmbH revolutionized the electroplating industry with the introduction of mechanical butt welding for electroplating barrels. With this pioneering work, the company has set a standard in barrel production that has not only significantly improved their mechanical properties. This manufacturing method also has a positive effect on quality and process reliability for users when electroplating large quantities.

Galvanizing barrel bodies almost from a single cast

Machine butt welding (polyfusion) creates an absolutely homogeneous connection between the barrel components, resulting in an extremely resilient, torsion-resistant and crack-proof barrel construction. The individual parts of the drum are joined in this process in such a way that there are no gaps or weak points at the joints. The entire drum body is virtually made from one piece. Even the smallest pieces of fabric do not get stuck in the corners between the wall and drum shell, which is a common problem with other manufacturing methods, such as plugged drums or manually welded drum constructions.

Gap and crack-free drum construction as a prerequisite for fabric drying

A gap- and crack-free drum design is also a prerequisite for product drying, for example in the Galvadry drum dryer, or for the automated emptying of residues, for example in the Galvarob lid opening station. If residual materials from gaps or cracks get onto the goods during the drying process, this inevitably leads to rejects or quality problems. To this day, automatic butt welding is an outstanding feature of Tscherwitschke electroplating drums, from which electroplating companies benefit on a daily basis.
