Abstract
There is currently a demand for numerical tools to support the design process of overmoulded structures as determination of interface strength may currently only be determined reliably from experimentation, which is limiting due to tooling costs. Simulation of the injection overmoulding process represents a complex challenge as the final interface strength is dictated by polymer bonding mechanisms and the microstructure of the interface which are dependent on material characteristics and processing conditions. In this work a multi-phase Computational Fluid Dynamics (CFD) simulation is presented which shows the initial micro-scale development of the interface during overmoulding using the volume of fluid (VOF) method to further understand and simulate the development of the interface morphology. Thus far the numerical model has captured the solidification/melting process and the subsequent development of a stratified flow phenomenon which can explain the formation of complex interfacial features that have been observed experimentally.
