The fourth episode of #AskGlaston Flat Tempering Series covers the safety; how to verify that all glasses are tempered.
In glass tempering, it’s essential to ensure that every glass leaving the factory is properly tempered. Currently, standards require tempering a small test piece once every hour or with every change in product. This means that most of the produced glasses are actually not tested at all.
Glaston’s Online Stress Calculation system enables the measurement of results for all produced glasses, significantly enhancing safety. Online Stress Calculation works by using real-time process data to calculate surface stress and middle pane tension in all produced glasses.
This ensures accurate tempering results and allows manufacturers to define their own acceptable stress levels. The system also estimates expected fragmentation, supporting compliance with safety standards.
By identifying the correct tempering level, Online Stress Calculation helps optimize energy use, reduce costs, and improve overall process efficiency. Its modular design allows easy upgrades to existing machines, and Glaston’s support network ensures long-term success.
In short, Stress Calculation offers a reliable, data-driven method for verifying glass tempering quality and maintaining high production standards.
