MM400-3 encaustic tile machines are the most simple and economical presses. They have one or two mould moving in line. The pressing, as well as the demoulding of the tiles are made in the central station. In the lateral stations the material is poured, then vibrated to spread it evenly and to eliminate the air bubbles that generate in the mixture. The pressing powers go from 100 to 150 ton. The sizes are 250x250mm, 300x300mm, 400x400mm,etc. The face-layer is made of wet conrete which can be added with pigment. The bottom-layer is made of semi-dry materials. The thickness of the tiles ranges from 25 to 80mm.
