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.

1. A method to produce a cylindrical metal-sealing material-feedthrough, said method comprising the steps of: producing a cylindrical plate-like body by providing a blank;processing said blank so that a feedthrough-opening is incorporated into a ring-shaped or plate-like element created from said blank, said feedthrough-opening extending from a back side of said blank to a front side of said blank, said processing step including forming a relief region in said blank extending from said back side toward said front side using a cold forming process, the relief region having a height HF, the step of forming the relief region defining a reduced thickness region DR, said reduced thickness region DR having a thickness being not greater than 3 mm;punching through the reduced thickness region DR to form the feedthrough-opening;producing a sealing material including at least one metal pin embedded in said sealing material; andinserting said sealing material with said at least one metal pin into said feedthrough-opening extending from said back side to said front side of said ring-shaped or plate-like element. 2. The method to produce a metal-sealing material-feedthrough of claim 1, wherein said blank is cold formed from a cylindrical wire-shaped material. 3. The method to produce a metal-sealing material-feedthrough of claim 2, wherein said cold-forming process includes compression. 4. The method to produce a metal-sealing material-feedthrough of claim 3, wherein said compression takes place along a longitudinal axis of said blank formed from a wire-shaped material. 5. The method to produce a metal-sealing material-feedthrough of claim 2, wherein said ring-shaped or plate-like element has an essentially round outside contour and said feedthrough-opening is located in a center of said ring-shaped or plate-like element. 6. The method to produce a metal-sealing material-feedthrough of claim 2, wherein, to incorporate said relief region, one of said ring-shaped or plate-like element is pressed against a punch and a material of one of said ring-shaped or plate-like element flows around said punch. 7. The method to produce a metal-sealing material-feedthrough of claim 6, wherein an essentially conically tapering feedthrough-opening is punched through said reduced thickness region DR. 8. The method to produce a metal-sealing material-feedthrough of claim 2, wherein cold forming said blank, providing said relief region, and punching said feedthrough opening occur in an essentially equal amount of time. 9. The method to produce a metal-sealing material-feedthrough of claim 2, wherein, to incorporate said relief region, a punch is pressed against one side of and one of said ring-shaped or plate-like element and a material of and one of said ring-shaped or plate-like element is pushed out on a side opposite said side of said ring-shaped or plate-like element. 10. The method to produce a metal-sealing material-feedthrough of claim 1, wherein said method further includes heating said ring-shaped or plate-like element and said sealing material, as well as subsequent cooling, so that a connecting bond is formed between said ring-shaped or plate-like element and said sealing material. 11. A method to produce a cylindrical metal-sealing material-feedthrough, said method comprising the steps of: producing a cylindrical plate-like body by providing a blank;processing said blank so that a feedthrough-opening is incorporated into a ring-shaped or plate-like element created from said blank, said feedthrough-opening extending from a back side of said blank to a front side of said blank, said processing step including forming a relief region in said blank extending from said back side toward said front side using a punch, the relief region having a height HF, the step of forming the relief region defining a reduced thickness region DR, said reduced thickness region DR having a thickness being not greater than 3 mm;punching through the reduced thickness region DR to form the feedthrough-opening;producing a sealing material including at least one metal pin embedded in said sealing material; andinserting said sealing material with said at least one metal pin into said feedthrough-opening extending from said back side to said front side of said ring-shaped or plate-like element. 12. The method of claim 11, wherein the processing step includes: forming the relief region in said blank by pressing the ring-shaped or plate-like element against the punch; orforming the relief region in said blank by pressing the punch against the ring-shaped or plate-like element.
