The numerical simulation of the non-isothermal melt densification in the rotational molding process is presented. The simulation combines heat transfer, polymer sintering and bubble dissolution models, and is based on an idealized packing arrangement of powder particles. The predictions are in agreement with experimental observations presented in the literature. The simulation allows for systematic and quantitative studies on the effect of molding conditions and material properties on the molding cycle and molded part density.
