Glass: separation, bending, joining

The laser-induced spontaneous plate glass separation technique that we developed (Joseph-von-Fraunhofer Prize 2008) creates a smooth, almost defect-free edge compared to conventional cutting processes, in which micro cracks are generated along the cutting edge. Our recently developed plate glass bending technique enables us to form panes much faster, cheaper and more exactly in different geometries. Even small batches can be produced more profitably and quickly than using conventional methods. We have also developed a highly vacuum-tight and stable soldered joint technology for glass with which to produce large panes of heat-insulating glazing. This means that large double-glazed panes with high thermal expansion can still maintain an insulating vacuum.
