Circularity and Integration of Functions for Metal Surfaces by Plating on Plastics in Automotive Series Applications
摘要
High-quality and sustainable surfaces are an important step in designing the automotive interior and exterior of the future. Next generation car designs have to consider the aspects of sustainable production and long-life application in the field in combination with recycling concept after the use case. Clever material combinations and new processing technologies for circular products have to be established. Electroplated polymers have several advantages for every step in this discussion to enable sustainable decor elements with integrated functions. Using a process developed by the BIA Group and industrial partners, metal and plastic in electroplated decorative components can be separated with a very high degree of purity in the polymer fraction. Without any chemical treatment a degree of 99,8% purity in the polymer fraction is achieved and can directly be used for new products. By focusing plated polymer parts, the substrate material is limited to ABS plating grades and ensures a very low probability of contamination by other polymers. The metallic fraction is recycled by the well know processes for metal and steel recovery. First products with a recycled content of 30% are now in series production. Because of the high purity of the material, a down-cycling is not necessary and these products are high quality surface parts in the automotive interior. The quality matches the known standard of parts with virgin material. The recycling content has no influence on the adhesion of the coating or the resistance to environmental influences. Specification requirements like DBL 1665, TL 528 or GS standards are passed. With the integration of ambient lighting and touch controls on real metal surfaces, these components are equipped for functional integration into the environment in the interior.
