Abstract

In a method for manufacturing a nozzle plate, two parts of the nozzle plate are fabricated separately from one another. The fabrication of the two parts is carried out by microstructuring/lithography, electroforming and plastic molding. Advantageously, a filter structure is provided in the first part. The two parts are joined together by means of laser welding, diffusion soldering or a chemical joining process. The nozzle plate is particularly well suited for injection valves, atomization nozzles, paint spray nozzles or other spraying systems.
