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.

What is provided is a precast hollow block, a precast wall system incorporating the precast hollow block, and forms for manufacturing a hollow block and a coping cap. Accordingly, the precast hollow block and its incorporation into a precast wall system provide solutions to current “level up” block coping techniques, wall flood protection, wall force protection, and the like. Instead of having mismatched or missing face textures on sloped portions of the wall, the precast wall system allows for easier installation of face-textured blocks directly at the top of the wall. As a result, the precast wall system may readily account for slope transitions of a wall, conform to specific Department of Transportation project requirements, accommodate existing wall construction specifications, and be easily customizable for a variety of applications.

A second mold is placed on a planar surface of a first mold to form a first mold cavity, which is filled with a first material slurry containing a first material powder and the molded slurry is caused to set, thereby forming a first molded part on the planar surface of the first mold. A third mold is placed on the planar surface of the first mold from which the second mold is removed and on which the first molded part is formed, thereby forming a second mold cavity. The second mold cavity is filled with a second material slurry which contains a second material powder different from the first material powder so as to mold the slurry in contact with the first molded part. The molded slurry is caused to set, thereby forming a second molded part on the planar surface of the first mold.

The disclosed subject matter concerns earth based mixtures, methods of preparing mixtures, and a process of forming articles of manufacture, as well as a process of manufacturing articles in molds configured for compression molding of earth based mixtures in accordance with the disclosed subject matter, including mixtures containing one or more of, e.g., sand, silt, clay, minerals, or any combination thereof.

A method for adjusting a sidewall unit (1) of a casting mold for concrete products, which sidewall unit comprises a support structure (2, 32, 42) and a mold surface plate (3, 3′, 33, 43) fixed to the support structure, and which sidewall unit is fixed on a casting bed (8), wherein the mold surface plate comprises at least two portions (3, 3′) extending along the length of the sidewall unit and connected to the support structure (2) and the vertical position of at least one of the portions (3), defined by orientation of the sidewall unit (1) fixed on a casting bed (8), is adjusted to form a gap (9) extending along the length of the sidewall unit between the portions. The invention also relates to such a sidewall unit.

A molding equipment and method to mold stackable inter-engaging bricks, blocks, stones and the like and bricks, blocks, stones and the like produced therewith are disclosed. The molding equipment comprises a main structure which contains individual cavities. Each cavity preferably has a middle structure to which a brick separating element can be attached. Without the brick separating element, each cavity can form two attached splittable bricks whereas with the brick separating element attached, each cavity can hold two individual smooth or embossed face bricks. The size and shape of the stackable inter-engaging bricks is such that once out of the mold but still in an uncured form, the brick can stand on its side without falling down, being damaged, buckling or being otherwise deformed during the manufacturing process.

An energy dissipater comprising a plurality of periodic hyperbolic surfaces, forming a continuous surface-structure, and enveloping contiguous tunnels there through.

Disclosed is a board structure for manufacturing concrete products, wherein a board used to manufacture a concrete product, for example, concrete blocks, paving stones, etc. is formed of an upper layer and a lower layer, and a side support frame connecting the upper layer and the lower layer, so it does not need to manufacture molds for each size, and a portion that receives external weight during the manufacturing of concrete products can be reinforced, thus obtaining substantial strength and lightness, and the manufacturing does not cost a lot while reducing noises during the manufacturing of concrete products.

The present invention relates to a mold and a pressure piece for producing molded bricks, in particular molded concrete bricks, a process for producing this mold or this pressure piece, an apparatus for producing molded bricks, a vibratable base for producing molded bricks, a metal drawing sheet for producing molded bricks, and also the use of a coating comprising an antiwear matrix and an antiadhesion component for surfaces of molds and/or pressure pieces and/or vibratable bases and/or metal drawing sheets used for producing molded bricks.
