<p>A method for producing a part (10) having a housing (20) that comprises an opening (25) that opens onto a free surface (15) of said part (10). The method comprises the following steps: (a) Closing the opening (25) with a sheath (30), the sheath having a discharge port (31) and a filling port (32), (b) Filling the housing (20) with an abradable material (50) consisting of particles by using the filling port (32), and creating a vacuum in the housing (20) by using the vacuum port (31), (c) Sealingly closing the ports (31, 32), (d) Deforming the sheath (30) in such a way as to compress the abradable material (50) in the housing (20) and heating the abradable material (50) to a temperature higher than 150°C until the abradable material (50) sinters, (e) Subsequently lowering the temperature and the pressure.</p> |
