Process chains for the production of micro-structured functional surfaces in plastics and metals

The functionalization of technical surfaces by microstructuring opens a variety of interesting possibilities, i.e. the generation of stain-resistant surfaces, the specific modification of the tribology of sheet metal or biomechanical optimized implant surfaces. While research in the physical and technological fundamentals of the effects has progressed already far, the realization of suitable production technologies and equipment for the commercial fabrication requires new innovative solutions. Not only plastics but increasingly also high-strength materials such as steel or titanium have to be microstructured economical and process sure. Therefore, process chains for the replication of functional structures especially by embossing or rolling techniques including the necessary equipment technology and tool manufacturing are developed at the Fraunhofer IWU. The functionalization of prototype surfaces by chipping complete the field of activity.
