The new environmentally friendly hybrid anode can do both: it not only benefits the environment, but is also the key to being able to electroplate even complex, 3D-printed components with a high degree of precision.

More than 1,200 trade visitors travelled to Karlsruhe for this year's DeburringExpo with specific tasks and a high demand for information. The majority of the 107 exhibitors are expecting good follow-up business. With over 500 participants, the trade forum also proved to be a sought-after source of knowledge.

Rund 90 Vorträge und Diskussionsrunden lieferten einen breit gefächerten Querschnitt über relevante Themen der Branche von Prozessoptimierung über Energieeffizienz bis hin zur Digitalisierung.

The Zeschky Group specialises in zinc and zinc alloy coatings, but also in coating systems such as cathodic dip coating and zinc flake and their possible combinations. With four locations and over 400 employees as well as a highly automated plant park, the company is one of the leading contract coaters. It all started in 1921, much smaller - and with coffee grinders.

AB Anlagenplanung GmbH, a company known for the design and implementation of customized coating systems, is taking over sales and consulting for the Aabo-Ideal Group in the DACH region as Aabo-Ideal GmbH.

With a new, automated technology based on X-ray fluorescence, precise monitoring of the metal concentrations of up to four electroplating baths is possible automatically and continuously.

A well-known Solingen-based manufacturer of high-quality, metallised plastic components for vehicles has been offering a take-back guarantee on its metallised plastic components since 2022. This is because the company fully recycles galvanised plastic components. The target is a lower limit of one third recyclate content in all products.

In order to achieve a higher degree of coating efficiency, the bulk material in this sputtering system lies directly on a special tube designed as a target and is continuously circulated by its rotation during the coating process.

Time and again, coating problems such as adhesion problems or insufficient corrosion resistance are caused by inadequate pre-treatment. In this case, excessive concentrations of substances in a silane-based pre-treatment process led to adhesion problems.

In Europe, a spectre is haunting all industrial sectors: The complete ban of PFAS. Where possible, some companies have reacted with foresight and developed alternatives. In the electronics industry, there are already ways to at least partially dispense with the controversial substances.
