Aluminum Connecting Rod Production

Aluminum Connecting Rod Production

There are two different options for aluminum connecting rods: billet aluminum and forged aluminum. To make a billet aluminum connecting rod, a solid block of aluminum that is 12-feet long and 3/4-inch thick is CNC machined. Forged and cast connecting rods are shaped using molds. 

Billet aluminum connecting rods have greater strength and durability than forged ones. Also, you can choose from many aluminum connecting rod material alloys. 

We have 100 sets of 3-, 4-, and 5-axis high-precision CNC milling and turning equipment, achieving tolerances of 0.002um. Precision, strength, and low-volume production support make HM the first-choice manufacturer for many clients.
