A new method for obtaining hollow moldings, which is essentially characterized by having inside the mold, a hollow, previously heated mass of thermoplastic material, whose edges are welded by the mutual pressure of the two parts of the mold, which it produces, at the same time, the cutting of the excess material, and then, in the interior of the aforementioned hollow mass, a fluid is injected by means of an animated injection piece of a forward movement, through the mold, when the operation is started, and of a backward movement when finishing the molding of the piece.
