Abstract:
A method for forming ceramic tiles comprising the following stages:loading ceramic powder to be pressed into a mold cavity;exerting an initial pressure simultaneously on the entire surface of the powder present in the mold cavity;releasing the initial pressure;exerting compacting pressure on the entire surface of the powder contained in the mold cavity;increasing the compacting pressure on a first portion of the surface of the powder contained in the mold cavity up to 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 and on said second portion alternately; andinterrupting the exertion of pressure.
