Abstract
A hydraulic extrusion press includes at least one ram, the ram being driven by hydraulic oil from a main line and a hydraulic control pressure being used to control the extrusion press. To minimize non-productive periods, the control pressure is also supplied to the main line. The main line and the pressure control system are connected with one another on the pressure side.
