The machine (100) has molds (10a,10b), and valve unit (5) operatively connected to the molds and comprised of valves (1,2) having an output arranged in direction of material to-be-molded and an input arranged in direction of pressure accumulator where pressurized medium is stored. The output of first valve is coupled to hollow article through sealable cavities. The input of second valve is connected to second pressure accumulator (S2) having lower pressure than first pressure accumulator (S1) such that the first cavity has smaller volume than the second cavity in one operating state. An independent claim is included for a method of forming a material into hollow article by pressurized medium. |
