Process for manufacturing reels, characterized by the fact of forming a molding cavity by coupling two or more side pieces, provided with complementary internal surfaces and defining the outer surface of the core of the reel and the internal faces of its walls, closing then the ends of this cavity by means of two axial stamps defining the external faces of said flanges, said stamps being provided with cores protruding from the internal face of the opposite one, of cross-section in the form of a circular crown segment and located stamped between those of the other with their mutually adjustable side edges, so that once coupled said stamps together form a hollow cylinder whose external surface is separated from the interior of the cavity and forms an axial housing that is pierced end to end by an axial core, also separated from the internal walls of said housing, proc Finally, the injection of a thermoplastic material into the spaces between the internal surfaces described.
