摘要

A method of manufacturing a turbomachine stator turbomachine stator annular wax pattern, comprising successively placing (38), in a mold, a core for forming the cavity cavity of a cavity. dawn of said assembly, the injection (48) of a wax into said mold, and the demolding (62) of the wax model equipped with said core, characterized in that said core is made of metal and is positioned so that its end radially internal is housed in the portion of the mold defining the blade having said cavity, away from the radially inner end of this portion of the mold.
