The method for producing a perforated disc

(57) Abstract: The present invention relates to a method for manufacturing a disc with holes formed in the multilayer, to form a flow-through portion for completely flow through the fluid, especially fuel in the axial direction, the through-flow the section, the inlet and opening (36) and outlet opening (38), and characterized by assembling from the at least one passageway positioned between the openings (42). In this case, the layer or functional plane of the perforated disc (23) and (35,37,40) is formed by overlapping the metal plating specific metal deposition (multilayer electroplating). Thus the perforated disc is manufactured is particularly suitable for use in the injection valve in the fuel injection device and for injecting or spraying a liquid such as a drink for example, for example painting nozzle, inhaler is suitable for use in ink jet injector or freeze drying process.
