The choice of colors is limited and the size of the pieces cannot exceed 400 mm in length, 250 in width and 100 mm in height. The pieces are dipped in a dye bath, then drained, rinsed and dried. The pigments penetrate deeply and completely into the walls of the part, which guarantees a better resistance to abrasion.
