GE Plastics has installed its fifth SCA-1500P automated stress measurement system from Strainoptics Inc. of North Wales, Pa.
The personal-computer-based instruments measure birefringence in polymer film. Other models are available that measure residual stress in extruded, thermoformed and injection molded products. GE Plastics uses the device in its resin plants in Mount Vernon, Ind., the Netherlands, Canada and China.
