Increase in power density by optimizing the design of the component geometries is a current tendency in developing powertrains in the automotive industry. This concept of lightweight construction can only be implemented to a limited extent by conventional manufacturing processes of machining for mostly economic reasons. This contribution presents a specific development by Fraunhofer IWU, showing that modern process chains based on forming technology enable near-net-shape manufacturing of complex components. By selecting suitable forming processes material can be saved when manufacturing a component. Furthermore, the process time may be reduced and the performance characteristics can be enhanced. The demonstrated example comp-rises producing splines by axial forming in only 4 s, while the hardness increases by 15 % in this area, which makes subsequent heat treatment dispensable. Finally the implementation of the developed powertrain concept is presented.
