Summary:An extrusion die for extruding a material and method of making a part using an extrusion die is disclosed comprising a cylinder, a cone mounted on the cylinder, an extrusion assembly having a core and a cylindrical tip. The extrusion assembly is positioned within the cylinder and cooperates with the cone and the cylinder to define a cavity. The cavity ends at an exit at the tip and the exit comprises an exterior defined by the reduction cone and an interior defined by the tip. A ram is positioned around the core and is movable from a retracted position to an extended position.
