Gravity slumping and vacuum-assisted slumping of thin glass

In gravity lowering, a thin glass is heated and formed under its own weight. Vacuum-assisted process control enables us to achieve high forming rates even with small surfaces, especially for thin glass with a thickness of less than one millimeter. Furthermore, the use of vacuum can significantly reduce the forming temperature, which has a positive effect on the service life of the forming tools. In addition, the tool occupancy time can be greatly reduced. For gravity lowering and vacuum assisted lowering, we develop automation solutions and manufacturing concepts for mass production.
