Glass Sheet Bending Process

Using the new laser based glass bending process it is possible to achieve precisely defined and extremely small bend radii so that even laminated safety glass can be bent around a corner.

Glass sheet bending process. However glass rods and tubing is easy to bend and frequently done by artists and people working in laboratories. Non isothermal processing of the glass with hot and cold areas within the glass sheet enables. A process for bending a glass sheet or a pair of glass sheets to a relatively sharp angle which comprises forming an electrically conducting path on the sheet along a line about which it is desired to bend the sheet and passing an electric current through the path to heat the sheet adjacent the path to a temperature above the bending point of the 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.

All you need is a flame. Bending a glass pane or bottle to a precise shape is not feasible without professional equipment. At fraunhofer iwm glass bending processes have been developed for forming sheet glass especially with application of local heating.
