Zusammenfassung:A cluster model and a shell for the production, by lost wax casting, of a plurality of turbomachine elements, are provided. The shell includes a central sprue that is fluidly connected to a casting cup for receiving molten metal; a plurality of shell elements; a plurality of bottom feed conduits for the shell elements; and a handling accessory shell that is independent of the plurality of shell elements and of their metal supply circuit, such that there is no fluid connection to the shell elements. The handling accessory shell is fluidly connected to the central sprue so as to allow top-pour casting of the handling accessory shell.
