Abstract: Mold assemblies for forming shaped glass articles are disclosed herein. According to one embodiment, a mold assembly may include a mold body including a mold cavity, a support base, and a plenum body extending between the mold body and the support base. When the mold assembly is heated to an average temperature of greater than or equal to about 650° C. by an overhead heating source, the temperature at the center of the mold cavity may be less than at the perimeter of the mold cavity. The difference between the temperature at the center of the mold cavity and the temperature at the perimeter of the mold cavity may be at least about 12° C.

Abstract: A method of making a shaped glass article includes placing a glass sheet on top of a mold. A heat exchanger is arranged relative to the mold such that a heat exchange surface of the heat exchanger is in opposing relation to a back surface of the mold and separated from the back surface of the mold by a gap containing a layer of gas. The height of the gap is selected such that the dominant heat transfer between the heat exchange surface and the back surface of the mold is by conduction through the layer of gas. The glass sheet is heated and formed into a shaped glass article with the mold. The heat exchanger is operated to remove heat from at least part of the mold during at least one of heating the glass sheet, forming the shaped glass article, and cooling the shaped glass article.

Abstract: A glass forming apparatus and method include a cooling mechanism in a wall of the apparatus that enhances radiation heat transfer between the glass and the wall of the apparatus and is tunable in both the vertical and horizontal directions. The apparatus and method also include a heating mechanism that affects radiation heat transfer between the glass and the wall of the apparatus, is tunable in both the vertical and horizontal directions, and is independently operable from the cooling mechanism.
