We are specialists for glass, ceramics and semi-conductor materials. Our core competencies lie in fracture mechanical analysis methods and manufacturing processes with a focus on hot glass forming, ultra precision processing, joining techniques and special separation and cutting techniques. A particular focus is placed on edge bonding techniques for vacuum insulating glass, low-damage machining techniques for precise contours in precision components as well as separation techniques for sheets of laminated glass. Our findings lead to solutions for new processes and products and to the informed assessment of their cost effectiveness and feasibility in industrial use.

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...
