WHO WE ARE & WHAT WE DO
VON ARDENNE develops and manufactures industrial equipment for vacuum
coatings on materials such as glass, wafers, metal strip and polymer films. These
coatings give the surfaces new functional properties and can be between one
nanometer and a few micrometers thin, depending on the application.

We supply our customers with technologically sophisticated vacuum coatingsystems, extensive expertise and global service. The key components are developed
and manufactured by VON ARDENNE itself.

Our customers use these materials to make high-quality products such asarchitectural glass, displays for smartphones and touchscreens, solar modules andheat protection window film for automotive glass.

VON ARDENNE develops and manufactures industrial equipment for
vacuum coatings on materials such as glass, wafers, metal strip andpolymer films.
By using our in-depth expertise in applying thin films, we haveidentified different approaches along the production chain of lithiumion batteries to improve their performance and cost-efficiency byfunctionalizing cell component surfaces.
Additionally, our novel technologies open promising paths tocircumvent existing challenges and enable alternative production
processes for the next-generation of lithium-ion batteries.
