Improvement of Material Modelling for Lightweight Bottles

Prof. Dr.-Ing. Christian Hopmann and Benjamin Twardowski, M.Sc. Institute of Plastics Processing (IKV) at RWTH Aachen University, Aachen, Germany

In order to reduce development time and costs, preform and process design in the two stage stretch blow moulding process of PET bottles is increasingly supported by simulation tools. An example are virtual bottles which support the early design process as prototypes or the production as digital twins.
