A device to compact parts out of powder material including a top die and a bottom die movable with respect to each other from an open position to a closed position, at least one punch associated with each of said dies for relative movement between the die and associated punch, said bottom die and bottom punch movable to positions defining a cavity substantially within said top die for receiving powder therein, said bottom punch and said top and bottom dies being relatively movable to draw powder down into a portion of said cavity adjacent the bottom die that is formed due to said relative movement, said top and bottom punches being movable toward each other to compact the powder and form the part, said top and bottom dies being separable to eject the part. Relative movement of the top and bottom die and bottom punch may take place during filling of the cavity with powder. Alternatively, relative movement may take place after the completion of filling the cavity adjacent the top die with sufficient powder to fill the part.

Split die and method for production of compacted powder metal parts

A method and apparatus for delubrification of parts. The method comprising the steps of moving the parts on the belt into a chamber of the furnace, heating the parts, igniting the unused combustible atmosphere above the parts, and allowing the atmosphere above the parts to escape through a vent in the chamber. The parts are heated uniformly by a heat source beneath the belt. The hot atmosphere is forced up through at least one plenum by blowers. The unused combustible atmosphere in the chamber above the parts on the belt is ignited using a burner and vented through the vent in the chamber.
