Abstract:
A method of manufacture of a wax model of an annular bladed turbomachine stator assembly includes in succession the positioning, in a mold, of a core intended to form the impression of a cavity of a blade of the assembly, the injection of a wax in the mold, and the removal of the wax model fitted with the core from the mold. The core is manufactured in metal and is positioned such that its radially internal end is housed in the portion of the mold defining the blade including the cavity, away from the radially internal end of this portion of the mold.
