According to LandGlass, when there are discrepancies in the curvature settings of the bending chillers in the glass tempering furnace, or when the glass deviates during motion, the bent tempered glass can have an inaccurate curvature and its diagonal corners could not lie on the same plane. In such instances, the curvature of the bending chiller in the tempering section should be adjusted and the location of the positioning baffle in the chiller corrected.
If cracks appear on the curved edge of the bent tempered glass, the air pressure in the bent chiller should be reduced. Additionally, it’s also advisable to slightly shorten the waiting time before blowing and reduce the bending speed of the chiller.
During the production process, if the curvature of the bent glass being processed changes, the curvature parameters should be readjusted. It might also be necessary to extend the heating time or raise the furnace temperature of the glass tempering machine and a check should be conducted to ensure the heating elements and thermocouples are functioning properly.
