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.
Claims13
A method for producing one of a ring-shaped and plate-like element for a metal-sealing material-feedthrough for a plurality of devices which are subjected to high pressures, said method comprising the steps of:
- providing a blank;
- and
- subjecting said blank to a processing so that a feedthrough-opening can be incorporated into said one of said ring-shaped and plate-like element created from said blank.
A method to produce a metal-sealing material-feedthrough, said method comprising the steps of:
- producing a plate-like body by:
- providing a blank;
- and
- subjecting said blank to a processing so that a feedthrough-opening can be incorporated into a plate-like element created from said blank
- producing a sealing material including at least one metal pin embedded in said sealing material;
- inserting said sealing material with said at least one metal pin into said feedthrough-opening of said plate-like element;
- softening said plate-like element and said sealing material, as well as subsequent cooling, so that a connecting bond is formed.
