The difference of the connecting rod manufacturing process: Forged vs Billet

Forging and billet as two different manufacturing processes to make high performance connecting rods, both can produce strong connecting rod when quality manufacturing processes and materials are used.


Forged connecting rods rely on mold. A blank piece of metal is heated to a temperature where it is malleable and then forced into the mold using high pressure, to make the metal take the shape in the form of a raw connecting rod, and then goes to final machining.

Generally Speaking , a connecting rod mold usually correspond to a connecting rod model or a few similar specs rods model . So that changes to a design or spec is complicated, maybe it will require a new mold, or altering the final machining  process . More importantly , developing a new mold will cost too much , about five of thousands of dollars to produce, even more . What's more, these molds eventually wear out and must be replaced, so it is a big production cost for the rods manufacturer. But forging rods offer increased strength and bright market environment in auto industry , it is highly suited for large volume production for a manufacturer to obtain a profitable return on investment. And from purchase cost , forging rod is also a good choice for buyers who has a stable connecting rod market .


Billet connecting rods made from a single piece of flat forged steel. The manufacturing process of billet rod does not rely on retooling or mold, so its designs can be easily changed according to customer's requirements, include strength , weight, appearance design ,specs customs etc. Since billet rods are often produced in smaller batches or in custom configurations, more time would be needed in creating the design, machine setup and final finishing, and additional labor would be involved, billet rods would be more expensive than a forged rod of the same material. But when need to develop a new rod model to test the market , billet rod is still a good choice .
