ABSTRACT:
A method and a mold used with this method for manufacturing cast spray diffusers is described in which, in order to prevent an expensive reworking of important corners and edges, the molded parts are formed is such a way that mold parting planes are moved out of these critical areas. In particular, the transitional area between a rotationally symmetric swirl chamber of a spray diffuser in the narrow mouthpiece channel and the outlet edge of the mouthpiece are each placed in one-piece molded parts that abut against these adjacent molded parts outside these areas.
