The adhesion of the components of two-shot parts is of decisive importance. However, due to the complexity of the processes, it has not so far been possible to provide a quantitative prediction of the resulting adhesion. In a joint work, the Institut für Kunststoffverarbeitung (Institute of Plastics Processing) at RWTH Aachen University and the Chair of Polymer Technology at the University of Erlangen-Nuremberg have developed a completely new approach for the prediction of adhesion in two-shot parts based on injection moulding simulation and FEM strength analysis.
