Patent

CA 2251918

A method for manufacturing artificial stone having a curved surface or a deformed shape comprising the steps of heating a plate-like artificial stone forming body whose surface has previously been polished or roughened to a temperature ranging from 120°C to 200°C under a pressurized atmosphere equal to or higher than 3 atms so as to soften and deform it to a predetermined curved surface or deformed shape and cooling it to a temperature not higher than 90°C.

Un procédé de fabrication d'une pierre artificielle présentant une surface incurvée ou une forme déformée sans avoir recours à un procédé de polissage pour surfaces incurvées consiste à chauffer un corps synthétique artificiel en forme de plaque dont la surface a été polie ou dégrossie à une température de l'ordre de 120 DEG C à 200 DEG C sous une atmosphère pressurisée égale ou supérieure à 3 atmosphères afin de l'adoucir et de la déformer pour lui donner une surface incurvée prédéterminée, et la refroidir en la ramenant à une température n'excédant pas 90 DEG C.
