Abstract

The invention relates to a method for producing a ring-shaped or plate-like element, in particular for a metal-sealing material-feedthrough, in particular for devices which are subjected to high pressures, preferably igniters for airbags or belt tensioning devices, whereby a blank, especially in the embodiment of a wire-shaped material is provided and the blank is subjected to processing so that a feedthrough-opening can be incorporated into a ring-shaped or plate-like element created from the blank.
