Glass Sheet Bending Process

German tech bends glass sheets at right.

Glass sheet bending process.

Tempering and bending of glass. The process of bending provides glass with a new functional and aesthetic quality. The glass is fractured and the unit manipulated into a desired shape. 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. A process for bending tempered glass. Bent glass units offered by press glass are made in a process based on tempering. 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 process involves adhering two sheets of tempered glass in overlying relation and positioning a containment barrier such as vinyl sheets over the adhered unit. Lamination bending is a process that somewhat combines cold and hot bending as well as lamination. All you need is a flame. Now though german scientists have developed a method of bending a single sheet of glass to a 90 degree angle without affecting its optical properties.

Once the adhesion has set the vinyl is removed. They are heated to suitable temperature then they are taken out and bent into the desired shape. 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. 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.

Glass bending is one kind of process in which rods sheets or tubes of glasses are bent into the desired shape by placing them in temperature controlled special ovens. 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.
