Claim 8:
9. A method for manufacturing a turbomachine fan casing made of composite material with the mold according to claim 1, the method comprising:
winding a fibrous preform of the fan casing around the mandrel;
assembling the plurality of counter-mold angular sectors on the outer contour of the mandrel by arranging a first counter-mold angular sector on the outer contour of the mandrel, the flat seal then being arranged on the sealing portion of the first counter-mold angular sector, a second counter-mold angular sector then being arranged on the mandrel by placing the sealing portion of the second counter-mold angular sector over the flat seal;
densifying the fibrous preform by injecting a precursor material of a matrix of the composite material into the mold;
polymerizing the precursor material to obtain the matrix of the composite material;
removing the plurality of counter-mold angular sectors;
de-molding the fan casing.
