Environmental Product Declaration / Sanitaryware The stages of the production process are as follow: Unloading of raw materials 1 Preparation of the slip 2 Casting 3 Drying 4 Mineral raw materials (clay, kaolin, feldspar The raw materials are taken to the mixer, Once the quality of the desired mixture Once the piece has achieved a mechanical and silica) are unloaded from trucks in the where they are blended with osmotic has been obtained and controlled by the consistency within the plaster mould, areas marked for this purpose. water. The resulting mixture is sieved and laboratory, the slip is pumped into the it is removed manually or automatically, pumped into the storage tanks and kept overhead casting tanks. From there, it depending on the lineor its difficulty. in suspension with the help of agitators. feeds the casting lines by gravity, where it These pieces are placed on trolleys and The paste resulting from this operation is injected into hermetically sealed plaster transported to the different dryers, where is known as slip. moulds, moulds in which the piece is they are dried with hot air. Once dry, they formed. are transported again by trolleys, this time Other pieces are also produced using to the polishing and enamelling line. plastic moulds with medium pressure slip injection, although to a lesser extent. The plaster moulds used are produced in the same plantand are manufactured by filling a mixture of plaster and water into araldite master moulds. After setting, the master moulds are separated and the plaster moulds are removed and transported to the dryers for their first dehydration prior to their use.
