  • Patent number: 6192730
    Abstract: A process for extruding a section or the like from a billet, in which a billet is introduced into the bore of a container and, by an extrusion stem, is fed in the direction of extrusion into a shape-forming cross-sectional opening in a die. The billet material is pressed into a central inlet in the die and the resultant ductile mass fed outwards at an angle to the direction of extrusion through a plurality of channels to the shape-forming cross-section. The main load is applied by the extrusion force acting outside the central inlet and the shape-forming region and is preferably diverted outside the shape-forming region to the supporting die parts.
