Aluminium Connects – Workshop with Allega and BWB

"Exploring new approaches together and learning from each other" – this was the motto under which the surface specialists from BWB Surface Technology met with colleagues from Allega GmbH. The focus was on the technical aspects of anodising and the plant visit in Oberdorf NW: Which alloys are particularly suitable for anodising? What are the limits of different processes? What does an anodising facility look like and which process steps are involved?

Tour and Preparation of Workpieces

The tour through the production halls of BWB-Betschart AG in Oberdorf NW offered fascinating insights into a modern anodising facility. The guests assisted in the production area and prepared components made of various aluminium alloys for surface treatment. Some processes were then tested directly on site, and the parts were sampled – including anodising and the subsequent red colouring of cast aluminium plates. In addition, rolled plates, sheet metal, angle, bar and tube profiles were anodised clear.

"The open exchange with BWB’s experts demonstrated the expertise and passion invested in every stage of the process. This transparency strengthens trust and makes us look forward to further joint projects," concluded Thomas Streiff, responsible for business development and sales processes at Allega GmbH.

At midday, BWB-Betschart AG hosted lunch in its canteen – prepared deliciously by Rosa, our experienced colleague from the masking department. Lunch offered an excellent opportunity to share impressions from the morning and get to know each other better.

"The workshop opens new doors – for Allega, for us and in the future for other partners in the supply chain," summarised Mladen Bilic from the sales team at BWB-Betschart AG.
