Abstract (en)
[origin: EP1048375A2] The cold forming method has a Cu workpiece with a volume corresponding to that of the required end electrode separated from wire with a diameter of 4.5 mm and clamped between a stationary forming matrix (10,11) and a relatively displaced forming stamp (30), moved in the direction of the matrix via a 2-stage forming process. An Independent claim for a cold forming tool is also included.
