Real-time polarimeter for fast and precise measurement of cord stresses in container glass
The fracture strength of glass is strongly determined by internal mechanical stresses. An inhomogeneous glass composition leads to so-called cord stresses, which remain undetected with conventional polariscopes or polarimeters. The manual measurement by means of a polarizing microscope is very time-consuming and requires specially trained and experienced operating personnel.
The StrainScope Cord Tester automates the stress measurement in ring sections of container glass and shows the distribution of compressive and tensile stresses in real time – directly in the desired measuring unit.
This allows you to perform the quality inspection close to production and with little training. You can respond quickly to production problems and avoid production losses and expensive complaints.
