Abstract (en)
[origin: CA3048294A1] The invention relates principally to a cluster model and a shell (1) for the production, by lost wax casting, of a plurality of turbomachine elements, the shell (1) comprising a central sprue (3) that is fluidically connected to a casting cup (2) for receiving the molten metal, and a plurality of shell elements (4). The shell (1) is characterized in that it further comprises a plurality of bottom feed conduits (5) for the shell elements (4) and a handling accessory shell (6) that is independent of the plurality of shell elements (4) and of their metal supply circuit, such that there is no fluidic connection to the shell elements (4), the handling accessory shell (6) being fluidically connected to the central sprue (3) so as to allow top-pour casting of the handling accessory shell (6).
