5. HYUNDAI FORGING January 11, 2016 5 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.

6. HYUNDAI FORGING January 11, 2016 6 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
