How is a rotary forged wheel manufactured?
Center Line has designed a rotary forging press, the only one of its kind in the world, to compress a solid billet of aluminum with 4,000 tons of force, at 300 revolutions per minute. Not only does this process rearrange the aluminum molecules, but it also aligns them in a circular pattern thereby adding strength. As a result, the rotary forged wheel has a much tighter grain structure and is significantly lighter weight than a cast wheel which requires greater mass due to its inherent porosity.
