Quality control of tempered glass
A frequent topic of discussion between glass processors and customers is the evaluation of tempered glass.
This is because anisotropies or deformations can occur here. Thiele Glas therefore relies on scanner systems that automatically check glass quality during production. This shortens production times, reduces the reject rate and also saves resources.
The term "anisotropies" in particular is a concern for architects, glass finishers, facade builders and building owners. Even if anisotropies do not represent a justified defect in the sense of product standards and visual assessment guidelines; architects, builders and facade consultants perceive anisotropies as a visual impairment.
Anisotropies cannot be avoided due to the process. But with the right technology, it can be significantly minimized. Thiele Glas uses such a technology. The anisotropy scanners check the glass quality of each glass pane directly at the furnace, which means there is no delay in the production process. The scanner displays the anisotropy value for each pane, documents it and provides information on whether the agreed target value has been reached.
But anisotropy scanners are not the only means of checking the quality of individual panes at Thiele Glas. Among other things, Thiele Glas has also equipped its production halls with Lite-Sentry scanners. With these, we create the conditions for the highest standard of precision and durability of the glass. The Sentry scanner measures deformations in tempered glass in the surface, edge and edge areas.
For larger and more demanding construction projects, we also create project-specific reference glasses for our customers in order to establish defined quality standards for the project. With the help of this reference sample, we can then deliver quality that is as consistent as possible throughout the entire production period.Back
