ABSTRACT:
A vacuum assisted feeding apparatus for delivering finely pulverized particulate materials, such as powdered metal, is disclosed in which a material holding hopper has a feeder tube extending into a lower disposed filling chamber subject to sub-atmospheric pressures to effect vacuum assisted gravity flow of the powder material into the filling chamber. Powder in the filling chamber is vacuum/gravity fed to a mold cavity until the cavity is filled, whereafter powder is accumulated in the filling chamber until the discharge end of the feeder tube is occluded by the powder to disrupt the feeding operation.
