Glass Sheet Bending Process

A process and a device for the bending on a frame of at least one glass sheet by gravity the bending being performed in at least two stages during which the glass sheet or sheets undergo a deformation by gravity.

Glass sheet bending process.

In a first stage the glass sheet or sheets are bent according to a first shape corresponding to a blank or precursor of the final shape. A process for bending tempered glass. Furthermore the process can also be used to bend a series of glass sheets to specific graduated radii so as to produce sandwich structures and sheets of laminated safety and insulating glass. The glass is fractured and the unit manipulated into a desired shape.

A stage for supporting the glass sheet. An apparatus and method for precision bending a glass sheet that includes an oven for heating the glass sheet to a temperature near the softening temperature of the glass sheet. Lamination bending is a process that somewhat combines cold and hot bending as well as lamination. After reaching the glass temperature close to the softening point the glass pane is curved to obtain the required shape and then quickly cooled down i e.

Bent glass units offered by press glass are made in a process based on tempering. German tech bends glass sheets at right. However glass rods and tubing is easy to bend and frequently done by artists and people working in laboratories. All you need is a flame.

At least one bending mechanism on a pair of arms inside the oven for bending an. Bending a glass pane or bottle to a precise shape is not feasible without professional equipment. Upon making shaping contact between the glass sheet and the male mold a vacuum is applied through holes extending through the male mold for a time sufficient to form the. The process involves adhering two sheets of tempered glass in overlying relation and positioning a containment barrier such as vinyl sheets over the adhered unit.

A pair of reference surfaces on the stage for precisely locating the glass sheet on the stage. A glass bending line for quickly shaping a complex bent glass sheet is provided that includes moving a ring type female mold which has a heated glass sheet placed on it and a full face heated male mold toward one another. For bent laminated glass the most common workflow is to first bend the glass sandwich with the desired number of glass sheets in the interlayer and then proceed with the autoclave process. Once the adhesion has set the vinyl is removed.
