Title: Method and device for producing a perforated disc for an injector valve, perforated disc for an injector valve and injector valve

Abstract: A method is provided for manufacturing an orifice disk. Metal foils are made available, opening geometries and auxiliary openings are introduced in the metal foils. The individual metal foils are superimposed in centered fashion. The metal foils are joined using a joining method, thus creating an orifice disk band having a plurality of rounds. Finally an isolation of the rounds or orifice disks is performed. The orifice disks manufactured in this manner are particularly suitable for use in fuel injection valves that are utilized in mixture-compressing, spark-ignited internal combustion engines.
