ABSTRACT:
A device for indirect extrusion of a hollow section from a billet, in particular a hollow aluminum billet, which is presented to a shape-giving orifice of a die, which is such that a container can be passed over it, thus enclosing the die, and features in its orifice a mandrel that determines the inner contour of the hollow section. A shaping recess is provided, with respect to the extrusion direction x, immediately in front of the shape-giving orifice of the die, the radial dimension of which recess is greater than the width of the shape-giving orifice. The shaping recess is provided either in the face of the die directed towards the extrusion stem or in the face of the extrusion stem directed towards face of the die.
