Abstract

The manufacture of an extruded metal component of the kind including a hollow substantially cylindrical body defining one or more axially extending splines at its external surface involves engaging a first punch with one end of a hollow, substantially cylindrical metal billet. The first punch is then used to perform an extrusion operation on the billet by causing the billet to undergo movement relative to a die cavity. The extrusion operation is arranged to cause material of the billet to flow so as to produce the required one or more axially extending splines and, during the extrusion operation, a load is applied to a second punch to urge the second punch against te other end of the billet. The load applied to the second punch is such that the second punch is moved relative to the die cavity by the material being extruded, but at the same time the material being extruded is shaped by the second punch so as to substantially fill the die cavity and thereby define the end of the component corresponding to the other end of the billet.
