Dynamic Computational Modeling of the Glass Container Forming Process

摘要

Recent advances in numerical simulation capabilities have made the modeling of glass container forming processes feasible. In this study, all stages of the gob/container forming processes were modeled in order to predict final bottle thickness and residual stress distributions. In addition to thermo-mechanical coupling capabilities, 'mesh-to-mesh' interpolation, mesh superposition, and remeshing techniques were used to allow a continuation of the calculations despite very severe mesh deformations. By modeling the entire forming process, insight into the impacts of the different forming stages on final container quality can be gained for the first time. These insights are can be used to develop new equipment, and control algorithms for increased production and pack rates.
