Claim:
1. A method of forging a shaped component comprising: positioning a billet in a lower press; moving an upper press into engagement with the lower press so as to locate the billet between the upper press and the lower press; striking the billet with a striking surface of an extension punch in a forging direction so as to force the billet into a cavity formed by the upper and lower presses, the cavity defining the shape of the shaped component; and moving the upper press and the lower press away from each other, wherein: the extrusion punch comprises a recess formed in the striking surface into which material from the billet enters as the billet is forced into the cavity, thereby locking the shaped component and the extrusion punch together such that both the shaped component and the extrusion punch remain locked together in the lower press as the upper and lower presses are moved away from each other.
