ABSTRACT:
A hydraulic trim press has a bed, stationary platen and a movable platen. The movable platen moves between the stationary platen and the bed on tie rods. The movable platen is driven by two spaced apart hydraulic cylinder and piston arrangements connected to a hydraulic circuit. A hydraulic tank for storage of hydraulic fluid is attached to the underside of the stationary platen. A manifold is secured to the top of the stationary platen to direct hydraulic fluid to the control valves and cylinders.
