Streszczenie: In order to be able to react to disruptions in global supply chains in a targeted manner, the development of process chains aimed at the repurposing of components in the powertrain of passenger cars is presented in this paper. Semi-finished products are obtained directly from end-of-life vehicles as secondary semi-finished products. After that, they are processed using bulk metal forming processes. For example, it shows how drive shafts can be reworked into connecting elements such as screws or gear racks in tie rods. Aspects to be considered are disassembling, separation and specific heat treatment if necessary to guarantee identical mechanical properties of the original product. On the one hand, this strategy contributes to significantly higher utilization. On the other hand, it demonstrates solutions for closing material cycles for automotive components.
