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 conductive heat simultaneously to a first major surface and a second major surface of a slab comprising particulate material, the first major surface separated from the second major surface by a slab thickness;
- and
- forming the slab to a mold while applying the conductive heat to the first and second major surfaces.
A method of thermoforming a slab, comprising:
- applying conductive heat simultaneously to a first major surface and a second major surface of a slab comprising particulate material, the first major surface separated from the second major surface by a slab thickness;
- and
- forming the slab to a mold while applying the conductive heat to the first and second major surfaces by heating a first conductive pad positioned on the first major surface of the slab and heating a second conductive pad positioned on the second major surface of the slab;
- wherein the resulting slab includes a curve having a minimum radius of curvature between 18 inches and 100 inches.
