ABSTRACT:
A press is described which is particularly suitable for the production of precision moldings from pulverized materials. The press is provided with a frame 3 in which a draft frame 5 and a platen 4 acting together provide the axis, and are connected to one another by means of a mechanical drive, preferably a toggle drive system, for relative movement to form a main press ram. In the main press ram, between the movable draft frame 5 and the platen 4, a hydraulic subpress 12 is arranged together with at least one additional axis, preferably however with several such axes. Control and regulation of the timing and extent of the working movement of each axis in the hydraulic subpress 12 are made to depend, through a control system 22-33, on the working movement of the main axis formed by the draft frame 5 and the platen 4 of the mechanical press 2.
