A method and system for forming ceramic tiles, including those with large dimensions, which includes the following stages: loading a powder to be pressed into a mould cavity; exerting an initial pressure on the entire surface of the powder present in the mold cavity; releasing the initial pressure; exerting the compacting pressure on the entire surface of the powder contained in the mold cavity; increasing the pressure on a first portion of the surface of the powder contained in the mold cavity up to a value permitted by the press capacity; releasing the pressure on said first portion of the surface of the powder contained in the mold cavity and increasing the compacting pressure on a second portion of the surface of the powder contained in the mold cavity; alternating the exertion of pressure on said first portion and on said second portion; and interrupting the exertion of pressure.

Device for forming ceramic tiles, including those of large dimensions

In a method for pressing ceramic powders comprising a powder compaction stage within a mold, after exerting the powder compacting pressure the powder is subjected to close-together pressure pulses while maintaining the compacting pressure applied.

Method for pressing ceramic powders

A method and apparatus for the dry-forming of crockery, using isostatic molds, wherein a powder is compressed within an isostatic mold and subjected to close-together pressure pulses during the exertion of the compacting pressure.

Method and apparatus for the dry-forming of crockery

A plant for forming ceramic tiles by means of a partially isostatic mold, comprising the following stages: loading the ceramic powder to be pressed into the mold cavity; exerting a uniform pressure on the entire surface of the ceramic powder present in the mold cavity; releasing the pressure and partially opening the mold to facilitate powder deaeration; exerting pressure on a first portion of the surface of the powder contained in the mold cavity; exerting pressure on a second portion of the surface of the powder contained in the mold cavity, while simultaneously nullifying the pressure on said first surface portion of the powder contained in the mold cavity; and alternating the exertion of pressure on said first and on said second portion alternately.

Apparatus for pressing ceramic powders

A pressure casting apparatus for molding sanitary articles which comprises a frame member, a lifting mechanism mounted in said frame member for up and down movement relative to said frame member, a plurality of molds positioned adjacent to each other and below the lifting mechanism, each mold being constructed form two lateral mold components which extend laterally from adjacent locking rods, an upper mold component and a lower mold component, said upper mold component being suspended from the lifting mechanism, the lateral mold components extending from opposite sides of the locking rod, and the lower mold components being disposed below said lateral mold components, said lateral mold components and said lower mold components being mounted for lateral movement within said frame members, and means for laterally compressing the lateral mold components and the lower mold components together, whereby the lateral mold components extending laterally from adjacent locking rods and an associated lower mold component combined with the lowering of the upper mold component to define the mold chamber used in the pressure casting operation.
