Method for producing separating nozzle elements

Method for producing a separating nozzle element including a separating body and terminal plates, for the separation of a gaseous or vaporous mixture, wherein the separating body comprises separating structures which penetrate the separating body and define separating chambers and gas conduits, and the terminal plates are provided with channels for the intake and discharge of gas streams, and wherein the separating structures are formed by producing a mold layer which contains negative outlines of the separating structures, and thereafter filling the negative outlines of the mold layer with a structure material which is compatible with the gaseous or vaporous mixture to be separated to form the separating structures, comprising:

• producing the mold layer containing the negative outlines of the separating structure by shaping the mold layer in a mold formed from the terminal plate and a reusable tool provided with the positive outlines of the separating structures, the mold being evacuated and then filled with liquid mold material to form the mold layer, the terminal plate being of such design that a form-locking band is established between the mold layer and terminal plate.
