This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

A method of manufacturing an artificial stone slab with veins comprises preparing a moldable hardenable fluid mixture of a first material (11); pouring the mixture into a mold (20) an upper face being exposed; engraving the exposed upper face with a predefined precise pattern of grooves (30) coinciding with a pattern of thin veins to be obtained; impregnating at least the inner faces (31) of the grooves (30) with a moldable hardenable fluid mixture of a second material (12), the color of both materials being different; causing the collapse and closure of the grooves, a visible pattern of thin veins of a second material with a natural look being left behind; curing the artificial stone slab by subjecting it to vibration, compression and vacuum until the fluid mixtures of the first material and of the second material are hardened.

Presented and described is a method for manufacturing concrete elements having at least one concrete layer, wherein concrete for at least one element is introduced into a mould, the concrete is compacted by vibration and/or by tamping and subsequently cures, wherein to the concrete layer, prior to compaction, at least one portion of a granular material is applied by means of an application device, where the concrete introduced into the mould has a water/binder (w/b) ratio of 0.30 to 0.50 prior to curing and where as granular material a material is used comprising (a) a scatter component having an average particle diameter of 0.1 to 5 mm in an amount of 65 to 95 wt % and (b) binder in an amount of 5 to 35 wt %, based in each case on the overall composition of the granular material.

This invention is an additively manufactured wall panel using computer aided design (CAD) and computer aided manufacturing (CAM) to design and manufacture multi-colored and multi-layered wall panels. This results in a variety of highly attractive, multi-colored wall panel faces ranging from brick, colored grout lines and multi-colored stones to multi-colored geometric designs. The design and manufacturing process greatly reduces the amount of precast cementitious materials by efficiently using higher quality materials. This reduces cost and weight while simultaneously producing a much more comprehensive, multi-functional wall panel complete with an interior frame, exterior insulation and an air, vapor and moisture barriers.

An apparatus for supplying material to a plant for producing slabs. The apparatus comprises means for supplying the material to be formed, first collecting and moving means, a conveyor cassette and second collecting and moving means. The means for supplying the material take the material from reservoirs and deposit it on the first collecting and moving means to form a semi-finished mat. The first collecting and moving means provide a stable base for the material and move the semi-finished mat towards the conveyor cassette, which receives the semi-finished mat and deposits a uniform pad on the second collecting and moving means. The second collecting and moving means provide a stable base for the uniform pad and move it towards successive stations in the plant. The conveyor cassette comprises at least one flap adapted to cross the entire thickness of the flow of material which, goes through the conveyor cassette.

The proposed solution solves a problem of designing a machine for producing molded composite parts that are homogeneously structured and the problem of finding a method for producing composite for implants. The essence of the design of the machine consists in that it has a portioning assembly, whereby above a mold form unit (14) there is a guiding unit (11) located opposite a dosing unit (6) and above the aforementioned guiding unit (11) there is a pressing assembly (20) slidingly mounted on a vertical frame (19) and which is equipped with at least one piston rod (25) with a rammer (27) at its end.

A preliminary molding is being performed by thoroughly filling a preform trough and then the matter is being pushed out of the preform trough in portions and then each portion is rammed separately until consistency containing less than 15% air is achieved.

A method and system for forming vertical wall construction units in one or more provided forms provides environmentally-manageable construction with reduced labor burden over existing non-traditional construction techniques. The method is a method of operation of the system, which includes a programmable controller, a reciprocating tamper head, a positioner that is guided to position the tamper head, and a filling mechanism for introducing loose material to a form in pre-determined layer volumes to provide loose material for individual layers of the prefabricated vertical construction unit. The programmable controller operates the filling mechanism to introduce the loose material for the current layer, then operates the three-axis positioner to guide the reciprocating tamper head over a horizontal cross-section of the form at a height determined for the current layer and along a program-determined path to compact the current layer. The process is repeated until the compacted material reaches a programmed height.

The present invention involves a multiplayer artificial stone and its preparation method. The decorative layer comprises the following components in percentage by weight: 80%-90% of a decorative stone, 5%-15% of an unsaturated polyester resin, 0.6%-2% of a coupling agent, 0.7%-1.2% of a curing agent, and 1%-5% of a pigment filler. The bottom layer comprises the following components in percentage by weight: 65%-78% of a calcium carbonate stone, 10%-18% of an unsaturated polyester resin, 0.6%-2% of a coupling agent, 0.7%-1.2% of a curing agent, and 1-15% of a pigment filler. The preparation method involves preparing the decorative layer and the bottom layer separately and then binding the two layers together by pressing. This arrangement allows the multilayer artificial stone to have good decorative effect and product quality; in addition, each layer contains only one type of stone, therefore its preparation is easier and can be more precisely controlled, lowering production cost.
