A process for the production of slabs made of mineral grits bound with resins comprises at least the phases of supplying a basic mixture that includes mineral grits and resins; loading the basic mixture inside at least one forming mold so as to obtain a laying surface facing downwards and an exposed surface facing upwards; compacting the basic mixture inside the forming mold to obtain a compacted slab; and hardening the compacted slab to obtain a slab made of mineral grits, wherein, after the compacting, a decoration phase with ink by digital printing of said exposed surface of said compacted slab is provided.

Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. The first particulate mix includes greater than 50 weight percent of first metallic particles.

Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. Locations of the first pattern have a first average thickness perpendicular to the slab width and the slab length, and locations of the second pattern have a second average thickness perpendicular to the slab width and the slab length that is different from the first average thickness.

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

This document describes systems and processes for forming stone slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, shower surrounds, tiles, or the like). In some embodiments, the stone slabs may be processed by partially filling a mold with a particulate mineral mix, and preparing a top surface of the particulate mineral mix to received one or more additional materials.

A dispensing device for dispensing a granular material, comprising a dispensing channel (20) provided with an inlet opening (21) and an outlet opening (22). The dispensing channel (20) comprises an intermediate portion (23), which connects the inlet (21) and outlet (22) openings and is provided with a longitudinal axis (Y); the intermediate portion (23) has a length (L) and a height (H), measured on a vertical plane containing the longitudinal axis (Y), wherein the height (H) is measured perpendicular to the length (L). The intermediate portion (23) is configured to enable the deposit and accumulation of a predetermined quantity of granular material coming from the inlet opening (21); Motor means are provided which can be activated on command to cause the granular material to flow in advancement from the intermediate portion (23) towards the outlet opening (22).

A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and printing on at least a top surface of the engineered stone.

A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and further comprising printing a printed pattern on at least a top surface of the engineered stone.

A Station (10 110) for the realization of coloring effects in a mix for the production of slabs, comprising:—a working surface (11) intended to accommodate a temporary support (12) with a basic mix layer for the formation of a slab;—at least one dye dispensing device (17) for emitting dyes towards the working surface (11) so as to deposit them on the basic mix layer on the temporary support accommodated on the working surface (11)—movement means (18 118) for the relative movement of the dispensing device (17) above the working surface (11)—a control system (19) connected to the movement means (18,118) for controlling the displacement of the dispensing device (17) on the working surface (11) so as to follow trajectories along which dyes are emitted towards the mix layer;—at least one tool (30, 31) movable with the movement means (18, 118) and intended to interact mechanically with areas of the mix layer on the temporary support accommodated on the working surface which receive or are intended to receive the dyes emitted by the dispensing device (17) to achieve coloring effects in the mix
