Titel
Investigations on glass-to-mold sticking in the hot forming process
Abstract
The sticking behavior of different mold materials was investigated. Sticking of different molds can be described by two material specific values: the "lower" and the "upper" sticking temperatures. A theoretical model was build and the factor which governs the "lower" sticking is identified: the viscosity of the glass in the glass-mold-interface. It was found out that it is not possible to raise the "lower" sticking temperature whereas the "upper" sticking temperature can be raised structured and coated materials.
