ABSTRACT:
A press comprises an open-topped cylinder in which a piston is moved by the injection of hydraulic fluid. The cylinder has a flange and is capped by a flanged lid. Clamping elements clamp the two flanges together. The plattens between which the high pressure reaction takes place are carried by the piston and by the lid.
