Analyses, further developments and tests on painting processes (with a focus on spray painting) are conducted at Fraunhofer IPA under realistic production conditions. We have a well-equipped surface technology centre, which even contains paint application robots. This allows us to conduct tests in order to assess the operating efficiency of application and drying systems – as well as their peripheral equipment – on all types of coating materials, in particular for applying innovative (e.g. nanoparticle) coating systems.
We also have a special piece of equipment, MicroCoat, for selectively applying paint without the need for masking. Its precise robotics allow us to use a wide range of application modules to apply paint to highly-specific points or areas.
We implement optical measurement techniques (LDA, PDA, Fraunhofer spectrometry, laser split beam) to analyse atomized (sprayed) paint. Our equipment includes measurement devices for characterizing the coatings applied and measuring layer thicknesses.
The complete coating process chain can also be virtually modelled with the aid of numerical simulations (especially fluid dynamics). This enables real tests conducted in the technology centre to be supported by computer simulations.
