Open Die Forging Press

In 2008, Oilgear Korea delivered a hydraulic drive and electrical control system to power a 6000T (60MN) Two Column Push Down Open Die Forging Press.

With a moving parts weight (WOP) of over 200 tonnes and a high pressure pipe column of over 28m, Oilgear was able to achieve a performance specification of over 150 strokes per minute with an accuracy variation of less than 1.0mm.  The hydraulic drive utilized the high performance PVV540 pumps, with the famous Oilgear Towler Fast Forging Valve.
