Prototype Draw Dies for Sheet Metal Parts 980078

State of the art is the CAD-development of personal cars. But as before it seems to be necessary to build up prototype dies for producing sheet metal prototype parts.Outgoing from the CAD-design of the sheet metal auto-body parts it is possible to design prototype dies using CAD, to produce patterns and dies using CAM and to stamp sheet metal prototype parts.So we get prototype parts for testing stiffness, crash behavior etc. and we get with prototype dies the possibility to test and to optimize the binder design of a draw die. The proven optimized binder design of a prototype draw die can be taken over to the design of the final production die.This paper deals with prototype die materials and with the criteria of the material selection.
