Driving innovation by understanding and simulating processes. Person photographed: Matthias Gremmelspacher.

We develop solutions for the hot forming of components made of glass. Discrete components are depicted in a pressing process (blank presses). Structures with optical or haptic functions, for example, are introduced into larger components using a local embossing process (hot stamping). 

Both processes are characterized by short process cycles, high surface quality and high contour accuracy. Consequently, optical components meeting the highest requirements can be realized.
