A preparing process for pressing particulate aggregates into a slab and a shaping apparatus are described. The preparing process includes: mixing particulate aggregates of different sizes and a liquid material as per a preset proportion to obtain a mixture; spreading the mixture flatly in a preset thickness onto a conveyor belt or into a mould frame; vacuumizing the mixture; shaping, wherein a pressing plate is disposed covering the mixture during the shaping procedure to constantly apply a downward pressure against the mixture; a ram disposed over the pressing plate continuously smashes the pressing plate, wherein during ram smashing, the pressure created by the pressing plate forms a continuous holding force to the mixture, the smashing force created from up-down motion of the ram is transferred to the mixture via the pressing plate.

Systems, devices, and methods are disclosed for a rosin press that allows improved extraction over existing presses. The press includes improved platens for rosin collection with built-in gutter rail collection systems and well-distributed force on the pressed product and multiple hydraulic rams. In addition, computerized systems are provided for controlling and monitoring the system in an automated fashion, as well as safety features to prevent injury and damage to the product, especially during automated pressing.

A method for manufacturing a laminate assembly may involve providing a decorative paper, impregnating the decorative paper with a first thermosetting resin, and laminating the resin provided decorative paper on a substrate. The decorative paper may be impregnated with a second thermosetting resin before being laminated.

A method for processing a smooth or structured surface of a pressing element is described, the method comprising the steps of: a) chrome-plating said surface of the pressing element so as to form a coating comprising a first layer having chrome grains oriented in a first direction and a second layer overlapping said first layer, said second layer having chrome grains oriented in a second direction which is different from said first direction; b) applying a mask on the chrome-plated surface of the pressing element by means of a digital printing technology; c) chemically treating the chrome-plated surface of the pressing element on which said mask was applied, said chemical treatment being performed so as to partially remove said chrome coating in the exposed areas of said chrome-plated surface, i.e. in the areas not being protected by said mask, and d) removing said mask from the chrome-plated surface of the pressing element, obtaining a smooth or structured surface having a coating with areas having a different grade of gloss and colour.

A pressing element obtained by the above processing method and a method for the production of coated panels, such as panels for furniture or floors, bearing a predetermined decorative pattern which uses such pressing element are also described.

A press base assembly, a strengthening ring for use with press bases and related methods are disclosed. In one embodiment, a press base assembly includes a press base having a body that includes a piston cavity at one end. The body, at a second end opposite that of the piston cavity, may exhibit a desired geometry. A strengthening ring may be shaped, sized and configured to substantially mate with the geometry of the second end of the body and be placed thereover. For example, the geometry of the second end may be substantially circular exhibiting a particular diameter and circumference. The strengthening ring may have substantially circular internal surface sized and configured such that the strengthening ring is positioned on the second end of the body in a manner that results in an interference fit between the two components.

High pressure presses, components for high pressure presses and related methods are provided herein. In one embodiment of the invention, a press base may include a piston cavity formed in the press base and a piston cavity sleeve positioned in the piston cavity. The piston cavity sleeve may include a wall having an outer surface and an inner surface opposite the outer surface. The piston cavity sleeve may further include a floor having an upper surface and a lower surface opposite the upper surface. An outer radius may be formed at a juncture of the outer surface of the wall and lower surface of the floor and an inner radius may be formed at a juncture of the inner surface of the wall and upper surface of the floor. The inner radius may exhibit a radius of curvature that is greater than a radius of curvature of the outer radius.

A mallet hammer tipping-detipping apparatus may include a press weldment. The press weldment may include a press base and a press neck extending from a surface of the press base. The mallet hammer tipping-detipping apparatus may include a press adapter coupled to the press neck. The press adapter may include a central recess such that a mallet hammer head may interface with the press adapter. The mallet hammer tipping-detipping apparatus may include a tip holder coupled to the base of the press weldment such that the press adapter is positioned above the tip holder. The tip holder may include a seating section in which the mallet hammer head may be positioned.

A link press assembly for use with a press to service a parallel link track chain is provided that includes alignment tools, disassembly tools, and reassembly tools. The alignment tools include a contact block, a plurality of block guide rods slidingly receivable within block guide rod passages of the contact block, a bridge plate for securement to a parallel link track chain, a plurality of elongated rod guides having plate guide rod passages, and a support block. The disassembly tools include a disassembly mount plate, an inner link support plate, a plurality of disassembly rods, an outer link support plate, and a disassembly tool bar having a plurality of pin bumpers. The reassembly tools include a back tool plate, a plurality of backing cups, a reassembly front tool bar having a plurality of front cups secured thereto, and a link hanger having a plurality of hanger guide rod passages.

A press head for a press machine used to press-fit a connector to a printed circuit board includes a press motor operable in a pressing operation, a driver assembly operably coupled to the press motor and movable during the pressing operation, and a press anvil operably coupled to the driver assembly and movable by the driver assembly during the pressing operation. The press anvil has a load cell housing holding a load cell and a contact plate coupled to the load cell housing and engaging the load cell. The contact plate has a contact surface configured to engage the connector or a seating tool for the connector and configured to press the connector toward the printed circuit board during the pressing operation. The load cell measures a pressing load of the contact plate during the pressing operation.

The disclosure relates to a pressing tool which has a structured pressing surface which is provided for producing, by pressing, a workpiece having a structured surface. At least one region of the pressing surface has a peg-shaped and/or rod-shaped structure with pegs and/or rods protruding from the pressing surface. The disclosure also relates to a workpiece which comprises a structured surface. At least one region of the structured surface comprises crater-shaped recesses in the structured surface, in order to confer a relatively matte impression on this region.
