A Moldex3D case study to show why it is important to consider the viscoelasticity behaviour of thermoplastic polymers:
Warpage prediction is essential to ensuring product quality and complying with specifications of unfilled and short fibre reinforced injection moulded polymer components. Therefore, it is necessary to consider the viscoelastic behaviour of thermoplastic polymers in order to get accurate simulation results. In this project, Moldex3D was used to investigate the effect of viscoelasticity on the warpage analysis. A methodology for the modelling and simulation of the warpage behaviour plus its validation was developed. The validation was performed in a test component and experimental 3D scans. The result showed that having correct characterisation and description of the viscoelastic behaviour is vital to achieving accurate warpage behaviour.
