ABSTRACT:
An air amplifier apparatus and method for transferring or filling sand particles into a flask of a molding machine. A plurality of nozzles are each mounted with respect to the molding machine. A pressurized fluid, such as discharged from an air compressor or other pressure forming device, delivers pressurized fluid into each nozzle. The pressurized fluid flows through a passageway of each nozzle and can follow a Coanda profile as it accelerates the particles through the passageways. The accelerated particles are then discharged into a void formed by the flask of and pattern in the molding machine.
