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.

A process for the production of slabs made of mineral grits bound with resins comprises at least the phases of supplying one basic mixture including mineral grits and resins; dispensing the basic mixture over a molding support so as to obtain a slab to be compacted provided with an exposed surface facing upwards and a laying surface facing downwards; compacting the slab to be compacted to obtain a compacted slab; and hardening the compacted slab to obtain a slab made of mineral grits; at least one decoration with ink by digital printing of at least the basic mixture carried out prior to the compaction, wherein the decoration phase includes at least one phase of pre-decoration by digital printing which is carried out prior to the dispensing and at least one phase of post-decoration by digital printing which is carried out after the dispensing.

A preparation method of a quartz stone patterned full-body plate includes seven steps of preparing a material, preparing a rough sheet, performing pattern treatment, preparing a pressing plate, baking, polishing and printing. Through matching the main materials with the pigment paste and color powders, especially each of the main materials is a mixture which includes at least three different ingredients, the preparation method improves the naturalness of the color and texture of the plate, making the plate closer to nature. Through matching different particle sizes of granular raw materials with silicon micro-powders in the mixture, the plate is able to obtain a uniform surface spherical effect. Through the cooperation of granular raw materials, silicon micro-powders, the pigment, the silane coupling agent, unsaturated polyester resin and the curing agent, the plate is able to obtain good earth resistant performance, abrasion resistance; is not easy to deform, crack, fade and tarnish; and has good decorative effect.

A masking fixture for coating dishware includes a support base having a first ferromagnetic member and a contoured support surface configured for engagement with a lower contour of the dishware. A mask base includes a second ferromagnetic member. The second ferromagnetic member is magnetically attracted to the first ferromagnetic member. The mask base includes a mask guide. A mask includes a masking surface configured for engagement with the upper contour. The mask is moveably coupled to the mask guide for movement between an engaged position in which the masking surface is engageable with the upper contour and a disengaged position. The mask can be moved to the disengaged position to facilitate removal of the mask base from the dishware after a coating operation.

A line for decorating and controlling products, in particular ceramic tiles and the like, includes a conveyor of products to be decorated, at least one decorating device of the jet type actuated by piezoelectric-control nozzles adapted to apply at least one layer of enamel on the products passing on said conveyor; the line further includes at least one control and diagnostic module of the decorated products, provided with means for detecting decoration and/or structural defects of the products themselves.

Foam products of a material having many voids or gas bubbles therein are marked by one or more of a plurality of devices capable of melting and/or vaporizing a desired pattern into a surface portion of the foam product, at least some doing so by movement of a hot tool, laser, flame, hot gas or other hot item, and systems and methods for making the mark or marks forming the desired pattern are disclosed along with the so marked foam products

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.

The invention presents a method and system for enhancing the aesthetics and functionality of 3D printed concrete objects. It involves an inkjet printing processes to improve the quality of the printed concrete objects. The method involves using a robot-mounted inkjet printhead, directed by a computer-controlled mechanism, to apply high-resolution imagery, colors, or patterns onto the object's surface while following the non-uniform contours of the object, including 3D printed ridges. The applied ink is then allowed to cure and bond with the object's surface. The invention enhances the detail and enables the application of high-resolution images onto 3D printed concrete structures.

Dispensing bar for a product, such as a granular or powder material, that includes a plurality of dispensing devices, each having a dispensing channel, provided with an inlet opening for the product and an outlet opening through which the product can be dispensed, a reservoir, placed in communication with the dispensing devices that contains the product, wherein the dispensing devices are distributed along an alignment direction, along at least one row, so as to define a deposition front parallel to the alignment direction such that it comprises a support structure, provided with a first portion, with which the reservoir is associated, and a second portion, with which the dispensing devices and the suction means are associated.
