A billet of material is received in a first cavity portion and struck by a striking portion of an extrusion punch so as to be forced into the corresponding second cavity portion to form a shaped component. The billet of material can be placed into either of the two cavities for extrusion. This may increase the number of extrusion operations that can be performed by a single die.
