摘要：
A process and apparatus for the indirect extrusion of hollow sections over a mandrel having a diameter d.sub.D from a plurality of billets each having a diameter d.sub.on wherein the volume throughput of metal is greater than that obtained by the indirect extrusion over a mandrel of said hollow sections from a single hollow billet under the same extrusion force thereby increasing productivity wherein the diameter of the mandrel d.sub.D with respect to the diameter d.sub.on of the billet to be extruded over the mandrel is d.sub.D
