Manufacture of laminated glazing
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.
METHODS AND SYSTEMS FOR PRESS BENDING TWO OR MORE PLIES OF GLASS
Various embodiments disclosed include a method of bending a glass laminate structure, the method can optionally include any one or any combination of: heating the glass laminate structure comprising at least a first ply substrate and a second ply substrate, wherein the first ply substrate has a first composition and a first thickness that differ from a second composition and a second thickness of the second ply substrate; engaging an edge portion of one or both of a first major surface and a second major surface of the glass laminate structure; and sequent to engaging the edge portion, pressing the glass laminate structure to bend the glass laminate structure and obtain a desired curvature of the glass laminate structure along one or both of the first major surface and the second major surface.
DEVICE AND METHOD FOR BENDING VEHICLE GLASS
A device and method for bending vehicle glass are provided in the disclosure. The device for bending vehicle glass includes a concave solid lower mold, at least one blowing pipe, and multiple extraction pipes. The concave solid lower mold includes a base and a top plate covered on the base. The base and the top plate cooperatively define an accommodating space. Multiple first partitions are arranged in the accommodating space to divide the accommodating space into multiple subspaces. The top plate has a carrying surface that is concave and away from the base. The top plate has multiple through holes that are in communication with the accommodating space and arranged at intervals. Each of the multiple subspaces corresponds to at least one of the multiple through holes.
Three dimensional microstructures and fabrication process
A method for fabricating three-dimensional microstructures is presented. The method includes: disposing a substantially planar reflow material between two molds; heating the reflow material while the reflow material is disposed between the two molds; and reflowing the reflow material towards the bottom surface of one of the molds by creating a pressure gradient across the reflow material. At least one of molds includes geometrics features that help to shape the reflow material and thereby form a complex three-dimensional microstructure.
METHODS OF FORMING SHAPED GLASS ARTICLES FROM GLASS SHEETS
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.
LOW COST WAFER LEVEL PROCESS FOR PACKAGING MEMS THREE DIMENSIONAL DEVICES
An apparatus and method for wafer-level hermetic packaging of MicroElectroMechanical Systems (MEMS) devices of different shapes and form factors is presented in this disclosure. The method is based on bonding a glass cap wafer with fabricated micro-glassblown “bubble-shaped” structures to the substrate glass/Si wafer. Metal traces fabricated on the substrate wafer serve to transfer signals from the sealed cavity of the bubble to the outside world. Furthermore, the method provides for chip-level packaging of MEMS three dimensional structures. The packaging method utilizes a micro glass-blowing process to create “bubbleshaped” glass lids. This new type of lids is used for vacuum packaging of three dimensional MEMS devices, using a standard commercially available type of package.
Methods for controlling separation between glasses during co-sagging to reduce final shape mismatch therebetween
Embodiments of the disclosure relate to a method of controlling the flow of fluid, such as air, between a stack of glass sheets during a co-sagging process. In embodiments, this involves a particular method and certain mechanical means of applying force at or near the edges and/or corners of a stack of glass sheets during a co-sagging process. In other embodiments, this involves creating low pressure regions at or near the edges and/or corners during the co-sagging process. In particular, controlling the flow of fluid between glass sheets is particularly suitable for preventing shape mismatch between two glass sheets having different thicknesses and/or compositions.
Rapid forming of glass and ceramics
A method for finishing a glass or ceramic article includes applying a force to the glass or ceramic article. The force is applied to the glass or ceramic article at least when the glass or ceramic article is at a temperature that is greater than or equal to a creep temperature of the glass or ceramic article. Holding the force to the glass or ceramic article as the glass or ceramic article is cooled to a temperature that is less than the creep temperature of the glass or ceramic article.
Methods of forming shaped glass articles from glass sheets
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.
Forming glass covers for electronic devices
A cover for an electronic device includes a glass cover defining a substantially planar first surface, a substantially planar second surface opposite the first surface, an opening extending through the glass cover, and a raised wall surrounding the opening and defining a portion of an interior surface of the opening.
