ABSTRACT:
A high density extruded product is continuously produced in a one step operation by first cold compressing granulated powder material in a bore into a pellet by means of a plunger reciprocable into the bore, then pushing it by the force of succeeding pellets further down the bore into a hot press zone where the pellet is sintered, and finally pushing it through an uncooled orifice into a cooling zone. The hot press zone may be heated by means of an induction heating coil. The die may be made up of a plurality of interchangable die pieces.
