Evaluation of the cold extrusion production process

This paper shows how a selected forming process (cold extrusion) can be evaluated by using the part information available from the CAD-system, e.g. volume, geometry and material. In particular the energy needed to form the part as well as the amount of zinc-phosphate coating necessary for the forming process are estimated based on this information. It is shown how the part information is retrieved from the CAD-system, how the cold extrusion process is modeled in an object-oriented manner and how the LCI data is obtained from this process model. Furthermore, the interface to an evaluation system is discussed
