Forging complex parts without flash.

Saving of resources becomes more and more important. Therefore the forging industry tries to develop processes with less flash than the conventional techniques or to avoid flash completely. Currently only simple parts like gears can be forged without flash. In a research project flashless forging processes for crankshafts were developed. In this paper the evolution of the flashless forging process and the process steps will be described. The collaboration research project 'process chain for the production of precision forged high performance parts' has been conducted in the last few years at IPH and is funded by the German Research Foundation (DFG).
