A forging apparatus and method is disclosed in which a die (130) has two separate cavities (140,145), each having a first cavity portion (141,146) and a second cavity portion (142,147). A billet (150) of material is received in a first cavity portion (141,146) and struck by a striking portion (162) of an extrusion punch (160) so as to be forced into the corresponding second cavity portion (142,147) to form a shaped component (155). The billet (150) of material can be placed into either of the two cavities (140,145) for extrusion. This may increase the number of extrusion operations that can be performed by a single die (130). |
