Inspecting every preform detail

Dr. Gerd Fuhrmann INTRAVIS GmbH, Aachen, Germany

One of the most challenging tasks in the field of quality control in the plastic packaging industry is the inspection of preforms. While bottles and containers are finished products and can be inspected in their final form, preforms have to be inspected thoroughly to detect any defect and therefore avoid problems during the further processing. The challenge for an inspection system is to provide detailed data about the object yet being suitable to inspect in a comprehensive and objective way without disturbing the production.
