Process perfected for the manufacture of hollow objects blown of thermoplastic material, consisting essentially of carrying out it between defined phases, in the first of which the thermoplastic material, by appropriate machine and row, is extruded in the form of a tube and coupled by its free end opposite to that of the extrusion die on the nozzle of an injector, proceeding next in the second phase to close the complementary parts of the mold on that nozzle and tube of thermoplastic material, while it is clamped by the opposite end by the mold itself, cutting it and separating it from the rest of the extruded tube, after which and as a last phase, a fluid is injected under pressure by that injector on whose nozzle the tube is attached, until the walls of the latter are completely adapted to the interior shape of the mold, using in all these molds whose parts complement preferably, a number of two are joined or two pistons actuated by a fluid under pressure, which governs the closing and opening of said molds, which, in turn, are cooled by a fluid at low temperature or previously cooled by a fluid to low temperature or previously refrigerated, which runs through internal ducts conveniently practiced in the mass thereof and preferably in the vicinity of their active zones.
