  • Mold cooling by recovery of energy from spent compressed air in blow-molding process
    Patent number: 7857613
    Abstract: Heat is extracted from compressed gas used in a blow-molding process by expansion cooling the exhausted gas and/or passing the exhausted gas through a vortex tube, which supplies cold gas at an exit thereof. The cold gas is then routed through cooling channels in the mold. This obviates the need for recirculating or externally chilling a coolant and saves energy.
    Type: Grant
