Abstract
A flashless metal connecting rod of the type having a one-piece construction and being fracturable into a cap portion and a body portion is produced by providing a precise preform of predetermined dimensions and a precise weight, induction heating the preform to a suitable forging temperature, sequentially compressing the preform between a plurality of unique sets of forging dies. The resulting final forging is both flashless and burrless. Preferably, the sequential compressing of the preform is accomplished through three sets of forging dies which progressively form the precision preform to its ultimate shape.
