Abstract
A method for manufacturing an orifice plate that is built up in multiple layers and includes a complete axial through passage for a fluid. The orifice plate includes inlet openings, outlet openings, and at least one conduit lying between them. The layers or functional planes of the orifice plate are built up on one another by electroplating metal deposition (multilayer electroplating). Orifice plates manufactured in this manner are particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, inhalers, or inkjet printers, or in freeze-drying processes, for spraying or injecting fluids such as beverages.
