Abstract: Embodiments disclosed herein include systems and methods for controlling material warp that include placing the shaped mold in a heating device, forming a glass material into a shaped mold, and cooling the glass material and the shaped mold to a predetermined viscosity of the glass material. Some embodiments include, a predetermined time prior to removing the glass material and the shaped mold from the heating device, holding the glass at the mold in the heating device where the heating device temperature is substantially equal to mold and glass temperature just prior to exiting to ambient temperature. Some embodiments include removing the glass material and the shaped mold from the heating device to further cool the glass material and the shaped mold at ambient temperature, where after removing the glass material and the shaped mold from the heating device, the glass material will exhibit controlled or desired material warp.

Abstract: A method of forming a 3D glass article from a glass sheet includes locating the glass sheet on a mold assembly including a mold surface with a 3D surface profile corresponding to that of the 3D glass article. The glass sheet is heated to a forming temperature. The forming temperature is greater than a temperature of the mold surface. The heated glass sheet is forced onto the mold surface by applying a pressurized gas to a first surface of the glass sheet opposite the mold surface to conform the glass sheet to the mold surface with the glass sheet at the forming temperature that is greater than the temperature of the mold surface.

Abstract: A process for forming a textured 3-D glass-based substrate includes texturing a first surface of a glass-based substrate and shaping the glass-based substrate into a three-dimensional shape. The surface profile of the substrate is non-planar. In some embodiments, texturing the first surface of the glass-based substrate provides the first surface with an average roughness of 10 nm to 2000 nm.

Abstract: Methods for compensating for the warp exhibited by three-dimensional glass covers as a result of ion exchange strengthening are provided. The methods use a computer-implemented model to predict/estimate changes to a target three-dimensional shape for the 3D glass cover as a result of ion exchange strengthening. The model includes the effects of ion exchange through the edge of the 3D glass cover. In an embodiment, the inverse of the predicted/estimated changes is used to produce a compensated (corrected) mold which produces as-molded parts which when subjected to ion exchange strengthening have shapes closer to the target shape than they would have had if the mold had not been compensated (corrected).

Abstract: A textured article is described herein that may include a glass-based substrate comprising a first major surface and a second major surface. The first major surface may be opposite the second major surface. At least a portion of the first major surface may be textured. The portion of the first major surface that is textured may have a roughness Ra of greater than or equal to 400 nm and an average pitch. A ratio of roughness Ra to average pitch may be from about 0.01 to about 0.04. At least a portion of the textured article may have an opacity of greater than about 70% or may have a coefficient of friction of from about 0.25 to about 0.4. The coefficient of friction may be measured as the kinetic coefficient of friction using a 500 g load on a foam rubber according to ASTM D1984.

Abstract: A glass sheet is formed on a mold into a glass article having a three-dimensional shape. The mold, with the glass article thereon, is arranged within an interior space of a radiation shield such that the mold is between a leading end barrier and a trailing end barrier of the radiation shield. The mold, glass article, and radiation shield are translated through a sequence of cooling stations while maintaining the mold between the leading and trailing end barriers, wherein the leading and trailing end barriers inhibit radiation heat transfer at leading and trailing ends of the mold.
