Improvements in the manufacture of hollow bodies of thermoplastic material, consisting essentially of obtaining by means of an appropriate machine and by injection a piece or first form of the body to be molded with the thermoplastic material, on a hollow core and in communication with the outside, whose core, covered by that piece, is then introduced into a mold with the final shape of the body, then closed said mold to inject air under pressure through the above mentioned core, until that piece is fully adapted to the interior of the mold, making both the extraction of that first part of the injection machine, such as its placement in the mold and subsequent air injection at a temperature that is sensibly constant and adequate precisely to obtain the permanent deformation of the plastic material.
