Abstract
A method 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.
