N2 - A thermal model for rotational molding is presented which includes heat, transfer from the oven to the mold, through both the mold and gradually depositing plastic layer, and to the unmelted but well-mixed powder. The problem is addressed numerically for the first time using Arbitrary Lagrangian Eulerian finite element methods. One dimensional results (spherically symmetric) show excellent agreement when compared with more limited numerical models, and when compared with experimental results from the literature and with the trends observed in practice. Extending these finite element techniques to axisymmetric cases may make accurate wall-thickness predictions possible.
