Manufacturing process - Forging
Open die forging of disc shapes involves progressive upsetting/forging to reach desired dimensions. Pierced discs are often used as preforms for saddle/mandrel rings and hollow forgings.

Manufacturing process – Ring rolling mill
Open die forging of rings starts with a preform on saddle/mandrel. Progressive reduction of the wall thickness to increase the diameter achieves the required dimensions. Subsequent machining then delivers the near-net shape
