Contactless inline 3D shape measurement with the patented stereo deflectometry process
Bending precision is a significant quality factor in parabolic mirror production, affecting the function of the product and the efficiency of the plant. FLABEG FE, world market leader in the glass processing industry, was looking for an inspection system for 100% online measurement of their produced mirrors and new products. The company wanted the in-process control to allow precise and repeatable measurement within the normal cycle rate, and to enable a fast and direct reaction to any defects. FLABEG found its solution in the form of ISRA VISION’s FORMSCAN – a system for contactless inline 3D shape measurement for glass with multidimensional bending.
The new ISRA VISION technology measures online the bending precision of the produced solar glasses, as soon as they leave the oven. Because the products are assessed directly at the bending oven, the operator can react to and counteract any defects extremely quick. “We chose ISRA not only because the solution was the best value for the money, but also we were aiming at the chance to correct defects immediately,” explains Dipl-Ing Andreas Seidl, Head of Process Technology at FLABEG. ISRA VISION is the only company in the world to offer such a comprehensive product range for the optical surface inspection of glass. The inspection systems are deployed at every stage of the process, from float glass production to the final quality control. The data gathered from the inspection systems also serves as a basis for process optimization.
