Abstract

The invention relates to a method and system for forming a metal sheet , preferably in the form of a disc, in order to obtain an essentially cylindrical and essentially hollow end metal part having a base thickness that is essentially greater than the thickness of its walls. More specifically, the invention relates to the metalworking sector and, in particular , to the production of ammunition cases or shells.
