Shafts drawn down from cast or rolled billet, with reduction ratio worked out for the finished section rather than assumed. Rings upset, pierced, and expanded over a mandrel for circumferential grain flow, with no part-specific tooling cost.
Ultrasonic testing planned around the forged grain structure, machining allowance set for as-forged surface and straightness, and heat treatment sized to the section. Low volumes and one-offs handled without tooling investment.
