There is provided a method for heating a thermoplastic plate to be subjected to bending which is horizontally arranged while holding at least part of a peripheral edge portion of the thermoplastic plate, causing a portion inside the peripheral edge portion to sag under a self-weight, and bending the thermoplastic plate to a desired curvature. The method includes applying tension in a planar direction of the thermoplastic plate at the time of holding at least the part of the peripheral edge portion of the thermoplastic plate in a molding frame defining a peripheral edge shape in a shape as a goal for reshaping. Since the thermoplastic plate is pulled in the planar direction during the heating of the thermoplastic plate, moderate tension acts on the thermoplastic plate to prevent breakage. The degree of curvature of the thermoplastic plate can be adjusted by adjusting the mass of each weight.

Methods for making articles comprising crystalline material. Exemplary articles made by a method described herein include electronics enclosure (e.g., a watch case, cellular phone case, or a tablet case).

Embodiments of a curved glass article are disclosed. The article includes a glass sheet having a first major surface and a second major surface opposite to the first major surface. The second major surface defines a first curvature of the glass sheet. The article also includes a display bonded to the second major surface of the glass sheet using an optically clear adhesive. The display has a perimeter with a display edge proximal to the first curvature. The article also includes a bumper piece disposed at least along the display edge proximal to the first curvature and a frame bonded to the second surface of the glass sheet using an adhesive. The frame is disposed around the display and over the bumper piece. In the article, the adhesive has a first modulus and the bumper piece has a second modulus that is greater than the first modulus.

A production device and production method for single curved tempered glass. Glass to be processed is heated in a heating section to a temperature required for a glass bending and tempering process; under the combined transfer of a ceramic roller group of the heating section and a forming roller group of a forming section, the heated glass enters the forming section, each roller of the forming roller group of the forming section being in the respective initial state, and under the action of gravity or other external forces, the glass is closely attached to the forming roller group and is then pre-formed accordingly; each roller of the forming roller group is bent from its initial state to a final state, and the softened glass after heating is, under the action of gravity or other external forces, closely attached to the forming roller group and is then formed accordingly; and air blowing and cold quenching are carried out until the formation and tempering of the glass are finished, thus obtaining a single curved tempered glass product.

Disclosed is an electronic device including a glass member having a flat portion and a side portion extending from an edge of the flat portion in at least a partially slanted or curved manner. The side portion includes a first curved portion extending from the flat portion, a second curved portion extending from the first curved portion and connected to the flat portion through the first curved portion, and at least one processing portion formed by at least a part of a border region between the first curved portion and the second curved portion. The at least one processing portion has a different refractive index from at least another portion of the side portion.

Provided is a method of thermoforming a molding material to have a bent portion and a flat portion extending from the bent portion. The method includes: placing the molding material on a bending mold, the bending mold having a curved surface; and forming the bent portion of the molding material by heating a portion of the molding material at least to a fluidization temperature such that the portion of the molding material bends due to the weight of the flat portion of the molding material to form the bent portion according to a shape of the bending mold.

A method for manufacturing a crystallized glass member having a curved shape includes a deforming step of deforming at least a portion of a glass plate into a curved shape by an external force that acts on the glass plate while maintaining the temperature of the glass plate within a first temperature range and precipitating crystals from the glass plate. In the method for manufacturing a crystallized glass member having a curved shape according to Claim 1, the first temperature range is from [At 40] C. to [At +40] C., wherein At ( C.) is a yield point of the glass plate.

A device and a method for bending, by gravity, a sheet of glass or a stack of sheets of glass including a plurality of sides, called the glass, including a skeleton for supporting the glass in its peripheral zone by a contact track, the contact track including concave curvatures on each of the sides of the skeleton, and a counter-skeleton capable of entering into contact with the glass in the zone of the middle of at least one side of the peripheral zone of the top main face of the glass.

A glass-based preform for a mirror of a heads-up display (HUD) system, including a glass-based substrate having a first major surface, a second major surface opposite to the first major surface, and a minor surface connecting the first and second major surfaces; a first chamfer at an edge of the first major surface, the first chamfer having a first end at an intersection of the first chamfer and the first major surface and having a second end at an intersection of the first chamfer and the minor surface; and a second chamfer at an edge of the second major surface, the second chamfer having a first end at an intersection of the second chamfer and the second major surface and having a second end at an intersection of the second chamfer and the minor surface. The first chamfer has a different size or shape from the second chamfer.
