摘要：
A Finite Element model of the plug-assisted thermoforming process has been developed to encompass both 2D axisymmetric and more complex 3D geometry. Initial modelling attempts assumed isothermal conditions, but for further improvement it is necessary to investigate the effects of heat transfer. In this paper the effects of heat transfer on the process are investigated. Heat transfer behavior at the plug and mold interfaces was identified and validated with the use of simple tests. The results were incorporated into the model of the thermoforming process and an improvement in wall thickness prediction has been demonstrated.
