During the last years the average weight of automobiles has increased significantly due to the increasing number of technical and safety features. Therefore the reduction of the vehicle weight by the use of light weight materials and advanced methods of light weight constructions has gained in significance for automotive industries within the last years. The overall objective of the collaborative research centre (SFB) 396 is to develop ideas for a modern way of manufacturing using robust, shortened and therefore low cost process sequences for sheet light weight parts. The focus on light weight construction originates from the desire for weight reduction on automotive parts which results in reduction of the primary energy consumption in transportation and adds a contribution to the reduction of CO2 emissions. The potentials for light weight constructions of aluminum, high strength steel grades and plastics as well as their combinations are investigated, especially in load-fitted designs. By the use of innovative processes and methods in planning, manufacturing and assembly, process sequences for the manufacturing of high quality parts can be shortened while keeping or even improving the quality standards. This also reduces product development time and production costs. The example of sheet light weight parts is ideal to prove the potentials of such a strategy. The process sequences presented in this paper refer to two of twelve sub projects of the collaborative research centre 396 with a focus in research in the following areas: Deep drawing of light weight materials with locally adapted properties and the combination of tube and double sheet hydroforming.
