We call the laser-based glass filamentation PearlCut, because the filaments in the glass look like pearls strung on a string. What could be more obvious than to call our laser systems PEARLs. Our PEARLs combine filament based glass cutting and CO2 laser cutting in one processing head. Filaments are used to weaken the glass, which is then separated by heating, expansion and the generation of tensile stress. Where cycle times require it, the two processes can be divided into 2 PEARLs arranged one behind the other. It is also conceivable to subsequently apply a mechanical breaking process to a PEARL filament process.
