The apparatus for forming large dimension ceramic tiles includes at least one first pressing unit () connected to at least one second pressing unit () by a conveying system () with which there may be associated at least one decorating unit for surface-finishing the blank formed by the at least one first forming unit, the at least one second pressing unit including two mutually movable superposed dies (), the lower of which is fixed and is positioned at the level of the conveying system, and the upper of which is movable in level between a raised position in which it awaits the arrival of the blank, and a lowered position in which it compacts the blank.

Method and plant for forming large-dimension ceramic slabs and tiles

Method for loading ceramic moulds presenting a die plate having at least one forming cavity in which a die is slidingly received, comprising the following operative steps for each complete loading cycle: preparing a powder layer at least the upper part of which has properties conforming to the required aesthetic characteristics of the exposed face of the tile; transferring said layer to above said at least one forming cavity; depositing into said at least one cavity a powder layer having a thickness greater than that necessary to obtain the desired tile thickness, and before pressing removing, by suction, the surface layer of the powder contained in the mould cavity, without appreciable mixing of the powder present at the interface between the surface layer and the underlying material.

A method for forming large-dimension ceramic tiles includes at least one first pressing operation for obtaining an incompletely compacted and consistent blank, and at least one second pressing operation for completing the compacting of the blank following an optional surface decoration, the at least one second pressing operation being effected without any lateral retention action on the blank.

A apparatus for pressure casting sanitary appliances including an outer framework, at least one block slidable within the outer framework arid having a male mould part and a female mould part, a fixed endpiece for said framework being provided with the male part which is adapted to be inserted into the female part of said at least one block, a movable head of the framework being provided with the female mould part which is adapted to receive the male part of said at least one block, means for thrusting said movable head in the direction of said fixed endpiece, and means for feeding pressurized slip into the cavities which form when said locks are positioned one against the other, wherein at least the mould portion defining the cavity of the female mould part is surrounded by at least one inflatable element provided with a pressurized fluid.

Pressure casting apparatus utilizing with two-part moulds

A casting mould made of porous material for forming sanitary appliances, including a plurality of profiled parts which are coupled together to define a casting cavity mould said parts being separable from each other for removing a formed appliance from the mould, means for introducing a slip into the mould cavity at least one insert member cooperating with said mould parts to form at least one undercut region in said appliance, wherein said at least one insert member is associated with one of said mould parts by way of a support unit located inside the casting cavity and comprising two mutually movable members, one of which is fixed and secured to one mould part, and the other movable member supports said at least one insert member and is able to move between a first, casting position in which it arranges said at least one insert member in the configuration which enables it to shape said at least one undercut region, and a second, removal position in which it disengages said at least one insert member from said at least one undercut region.

Casting mould for forming sanitary appliances

A highly versatile method for manufacturing ceramic tiles of different formats, a plant for its implementation, and tiles obtained thereby includes the following operational stages. First, a single panel is dry-formed within a ceramic mold by compressing at least one ceramic material in powder form. At least two tiles are then separated from said panel, after the formation of the panel but before a firing process of said panel. The plant for implementing the method incorporates a press of relatively large power with which there is associated a single-exit ceramic mold arranged to form a starting panel of large dimensions, and at least one sectioning unit provided downstream of the press to obtain at least one tile of the desired format from said starting panel.
