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.

A glass sheet forming and annealing system disclosed provides control of edge stresses by maintaining a press formed glass sheet on an annealing ring (72) below a heated upper forming mold (58) within a forming station (12) for slow cooling toward the glass strain point temperature.

A mold stack for forming 3D glass-based articles includes a plenum and a cooling structure integrated with the plenum. The mold stack includes a mold with a flange that can be used to mount the mold on the plenum. The mold stack includes features to reduce mold warp without significantly increasing thermal mass.

A method for bending sheets, in which a sheet is fixed in a bending chamber on a contact surface of a mold and is placed by the mold onto a frame, wherein the mold is introduced into the bending chamber before the fixing of the sheet in the bending chamber, without the fixed sheet, and is removed from the bending chamber after the placing of the sheet onto the frame, without the fixed sheet.

A shaped glass article is provided that is ultrathin, has two surfaces and one or more edges joining the two surfaces, and a thickness between the two surfaces. The shaped ultrathin glass article has at least one curved area with a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied. A method for producing a shaped glass article is also provided that includes providing an ultrathin glass with two surfaces and one or more edges joining the two surfaces, having a thickness between the two surfaces and shaping the ultrathin glass to a shaped ultrathin glass article by forming at least one curved area having a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied to the shaped ultrathin glass article.

Embodiments of this disclosure pertain to a vehicle interior system comprising a base having a base surface; and a glass article coupled to the surface, wherein the glass article comprises a first portion comprising a first elastically deformed surface forming a first concave shape with a first radius of curvature from about 20 mm to about 2000 mm, and a second elastically deformed surface directly opposite the first elastically deformed surface that forms a second convex shape, wherein the second elastically deformed surface has a surface compressive stress that is less than a compressive stress at the first elastically deformed surface, and a second portion adjacent the first portion, wherein the second portion is substantially planar portion or curved.

Embodiments of an article comprising a cold-formed glass substrate in a curved shape, a plurality of separate mechanical retainers, and a frame are disclosed. The cold-formed glass substrate has a first major surface, and a second major surface opposing the first major surface. In one more embodiments, the plurality of separate mechanical retainers are attached to the second major surface of the cold-formed glass substrate. The mechanical retainers may be attached to the frame to define a position for each of the plurality of mechanical retainers, such that the mechanical retainers define the curved shape. Embodiments of processes to form such articles are also provided. Such processes can include attaching a plurality of separate mechanical retainers to a flexible glass substrate such that the glass substrate maintains its flexibility, and attaching the mechanical retainers to a frame, such that the mechanical retainers attached to the frame define a cold-formed curved shape for the flexible glass substrate.

A method of processing a window member according to an embodiment includes applying a protective coating agent including at least one of a siloxane derivative and an inorganic sol compound onto a glass substrate, performing a heat treatment on the applied protective coating agent to form a protective layer on the glass substrate, thermoforming the glass substrate, and removing the protective layer, so as to process the window member without degradation of optical characteristics and without surface damages of the glass substrate.

A process for manufacturing a bent laminated glazing, includes manufacturing a first bent laminated glazing including at least two glass substrates locally comprising, in each of the at least two glass substrates and facing each other in all the at least two glass substrates, a zone including compressive stresses, and cutting the first bent laminated glazing through its entire thickness along a line included in the zone in order to form local cut edges and, after cutting, a second bent laminated glazing with the local cut edges having compressive edge stresses.
