The powder metallurgical (PM) process chain allows a resource- and energy-efficient production of powertrain components and, therefore, leads to a greener production process while being more economic than established cutting processes. Hence, PM powertrain components can be a cost-saving factor. Furthermore, current trends in automotive drivetrain development simultaneously demand for two challenging objectives: the increase of power density and lightweight design and the reduction of noise emission. The PM technology offers an integrative solution equalizing the trade-off between both aspects. With PM processes, multiple degrees of freedom arise compared to the conventional process chain regarding geometry and material properties.
