Abstract
A process for the manufacture of hollow bodies of plastic material, by means of blowing, characterized by the fact that the part to be molded expands and is cooled by means of a liquid gas, at a very high temperature, which flows to the molded part through a fine pipe, provided with a valve, which controls the machine's work cycle, having a blowing nozzle, and in which from the beginning to the end of the circulation phase, the gas at point The boiling point that flows through the blowing nozzle continuously changes from a gaseous state to a liquid state.
