Dörken Days 2025 - PFAS, new technologies and corrosion protection

The topic of PFAS took up a lot of space at the Dörken Days 2025. Dörken expert Sabrina Hilbt gave the participants a well-founded overview of the topic of PFAS, which continues to be a major concern for the industry. The guest contributions from two leading OEMs attracted particular attention. Dr. Pellkofer from Daimler Truck AG explained what the path to PFAS-free fasteners looks like and held out the prospect of PFAS-free products being included. He also presented the new Daimler Truck specification, in which the clear separation from Mercedes Benz has been implemented. Sine Groenne Karlsen from Siemens Gamesa again shed light on the topic from the perspective of the wind industry and focused on the future. She made it clear that wind turbines that are planned today and built in the future must be compliant with regulations. Siemens Gamesa has therefore decided to use PFAS-free products. Another highlight was the panel discussion to which Sabrina Hilbt invited the speakers as well as Walter Mauri from Agratt and Norbert Lewan from Galfa. Together they discussed the challenges of the entire supply chain in dealing with PFAS and what is needed to drive the issue forward.

New technologies at the Dörken Days 2025

A short break was followed by an exciting presentation by Florian Feldmann, Team Lead Analytical Services at Dörken, and Dr. Clara Linder from the Rise Institute. The two experts presented current projects of the institute, which deals intensively with corrosion, and gave interesting insights into the results of Dörken systems. Equally exciting was the presentation of the "LAMA" system - Laserbased Preparation of Mass bulk material for subsequent coating (zinc flake coating or galvanized zinc), which was presented by Olav Schulz from SLCR Lasertechnik and Christian Rabe, Team Lead Product and Application Engineering at Dörken. The laser cleaning of bulk material in preparation for subsequent coatings offered a fascinating look at modern technologies for improving corrosion protection processes. Tobias Kleyer, Technology & Networking Manager at Dörken, acted as moderator throughout the day. The host, Managing Director Christos Tselebidis, was visibly pleased and proud of the lively participation.
