ABSTRACT:
A pressurized feed shoe for delivering particulate materials to fill a die cavity is provided. The feed shoe includes a feed shoe body including a vessel for receiving a quantity of particulate material. The feed shoe body has at least one bottom egress opening for registering with the die cavity and a top ingress opening for receiving particulate material. A pressure generator for generating supra-atmospheric pressures within the vessel and the die cavity is also provided. The pressure generator communicates with the vessel via a conduit sealingly engaged thereto. A shuttle selectively moves the feed shoe body to and from a position whereby the bottom egress opening registers with the die cavity.
