A presently-preferred process for manufacturing a connecting rod (10) comprises placing a heated preform (11) suitable for being formed into the connecting rod into a closed forge die (50,70), and forging the preform in a first forging operation while the preform is at a forging temperature to for m an as-forged connecting rod (10a,10b) having vertical flash (26,27) extendin g therefrom. The presently-preferred process further comprises placing the as- forged connecting rod in a second forge die (60,80) while the as-forged connecting rod is at a temperature substantially equal to the forging temperature, and forging the vertical flash (26,27) in a second forging operation. The presently-preferred process also comprises removing the as- forged connecting rod from the second forge die, and machining the as-forged connecting rod to predetermined dimensions. |
