Modelling of Gob and Container Forming

摘要

Recent advances in numerical simulation capabilities have made the modelling of both glass conditioning and forming processes feasible. Glass forming operations include large free surface deformations, conjugate heat transfer, and complex contact phenomena. In this paper, glass container forming processes are modeled to provide insight into the impacts of the various stages of forming and conditioning on final container quality. The numerical model utilizes finite elements and includes the effects of viscoelasticity, surface tension, and time varying heat transfer. Special attention is given to areas that require further developments in numerical capabilities and an increased knowledge of boundary conditions and material properties.
