Various embodiments of high pressure presses and related methods of manufacturing and operating such presses are described. In one embodiment, a cubic press is described having press bases with spacers disposed between adjacent press bases. Sets of two or more tie bars are also disposed between adjacent press bases. The tie bars are placed in a state of compression while the spacers are placed in a state of compression. During operation, the press bases may become displaced relative to one another such that additional tension is experience by the tie bars while the amount of compression experienced by the spacer is reduced. The tie bars exhibit a relatively small cross-sectional area as compared to the cross-sectional area of the spacer.

A press tool for a press assembly includes an additive manufactured body including a plurality of stacked layers of additive manufacturable material extending between an interior side and an exterior side. The interior side has a part forming surface including a surface profile for forming a part. The exterior side has a plurality of hollow cores defined by longitudinal walls and lateral walls meeting at joints. Press inserts are coupled to the longitudinal walls and the lateral walls at the exterior side. The press inserts are configured to be pressed inward by a pressing load during a pressing operation for forming the part. The press inserts distribute the pressing load along the longitudinal and lateral walls.

A frame integrated vacuum hot press comprises a frame chamber including a vacuum space having an opened side; a door installed to the frame chamber to open or close the opened side of the vacuum space; a heating chamber including a heating space and a heater heating an object to be formed which is loaded in the heating space; and a cylinder which is connected to the frame chamber to apply pressure to the object to be formed which is loaded in the heating space of the heating chamber.

A uniaxial press for shaping pellets by compressing powder in a die by punches. The uniaxial press can be used in a restricted and hostile environment and includes small modules that can pass separately through narrow openings, the modules being assembled by placing over columns and by screwing, therefore by remote handling in the confined space where the press is to operate without requiring any further intervention. The actuation is generally exclusively electromechanical.

A modular press suitable for use in the manufacture of EWC products may include a plurality of frame modules coupled together and aligned along a feed path axis. Each frame module may have a generally planar body supported on a corresponding pair of bases, an elongate aperture, an upper and a lower platform within the aperture, and a platen between the platforms. Optionally, the ends of the aperture may be curved. A first actuator system may be operable to move the platen from a raised position to an intermediate position, and a second actuator system may be operable to press the platen downwardly from the intermediate position onto a workpiece within the aperture. Some modular presses may include conveyor rolls and a third actuator system to raise and lower the conveyor rolls. In some embodiments, the actuator systems may be pneumatic actuator systems. Corresponding methods and systems are also described herein.

Provided are an attachment pressing apparatus and a method of manufacturing a display device using the attachment pressing apparatus. The attachment pressing apparatus includes a body portion that is tubular and extends in a first direction, a wing portion connected to a side of the body portion in the first direction and extending in a second direction intersecting the first direction, a pressing portion penetrating the wing portion in an inner space of the body portion in the first direction and pressing an attachment, and a compression portion connecting another side of the body portion in the first direction and the pressing portion.

A hydraulic press includes a workbench having four corners provided with uprights. The uprights are arranged in two rows front and rear, and the tops of the uprights in each row are connected by an upper beam extending in a left-right direction. Tie rods are inserted in the front and rear of each upright. The tie rods each have an upper end protruding from the top of the upper beam and fixed to the upper beam by an upper nut and a lower end protruding from the bottom of the workbench and fixed to the workbench by a lower nut. A central cylinder is provided at the center of the upper beam. Side cylinders are symmetrically arranged on the left and right of the central cylinder. The lower ends of plungers of the central cylinder and the side cylinders are fixedly connected to a top of a slider.

A machine frame (1) for a roll press. This machine frame has an axial frame (2) for absorbing axial forces developing due to the operation and at least two radial frames (3) for absorbing radial forces developing due to the operation. The elements (36) of the radial frame (3), which absorb the radial forces, are mounted elastically in the machine frame (1).
