Abstract
Systems and methods of thermoforming stone slabs are provided, such as by heating a stone slab while forming it to a mold. Curved stone slabs may be produced having low radii of curvature.
Claims20
A method of thermoforming a slab, comprising:
- applying non-conductive heat simultaneously to a first major surface and a second major surface of a slab comprising particulate material and a resin binder, the first major surface separated from the second major surface by a slab thickness;
- and
- forming the slab to a mold while applying the heat to the first and second major surfaces.
A method of thermoforming a slab, comprising:
- applying radiant heat simultaneously to a first major surface and a second major surface of a slab, the first major surface separated from the second major surface by a slab thickness;
- and
- forming the slab to a mold while applying the radiant heat to the first and second major surfaces, the mold comprising a curved molding surface, at least one of the major surfaces of the slab urged toward the curved molding surface of the mold while applying the radiant heat to the first and second major surfaces of the slab;
- wherein the resulting slab includes a curve having a minimum radius of curvature between 18 inches and 100 inches.
