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.
