Claim Text:
1. A device for manufacturing parts with a rotational shape or a fan casing of a turbomachine made of composite material from a preform made of woven fibers, comprising: a rigid mold configured to contain the preform, the mold including a cylindrical body of lengthways axis and side flanges; a counter-mold including a cylindrical body and side counter-flanges, the counter-flanges being configured to he attached to the side flanges of the mold, the cylindrical body of the mold and the cylindrical body of the counter-mold being concentric, the preform being intended to be positioned in a space delimited by the cylindrical body of the mold and the cylindrical body of the counter-mold, a material of the cylindrical body of the mold having an appreciably higher thermal expansion coefficient than a thermal expansion coefficient of a material of the cylindrical body of the counter-mold; a device for injection under pressure of a resin into the space, the injection pressure being less than 4 Bar; and a device configured to produce a vacuum pressure in the space delimited by the mold and the counter-mold, wherein the counter-flanges and the flanges have substantially equal thermal expansion coefficients.
