Pros And Cons

Modeling and simulation of the morphology evolution of immiscible polymer blends during injection molding is crucial for predicting and tailoring the products’ performance. This paper reviews the state-of-the-art progress in the multiscale modeling and simulation of injection molding of polymer blends. Technological development of the injection molding simulation on a macroscale was surveyed in detail. The aspects of various models for morphology evolution on a mesoscale during injection molding were discussed. The current scale-bridging strategies between macroscopic mold-filling flow and mesoscopic morphology evolution, as well as the pros and cons of the solutions, were analyzed and compared. Finally, a comprehensive summary of the above models is presented, along with the outlook for future research in this field.

A mathematical model to predict the nucleation and cell growth during the microcellular injection molding without mold, was developed. The nucleation equation, energy equation, equation of cell growth, and equation of gas content were solved numerically. The predicted nuclei density and cell diameter were compared with the experimental results. The experimental equipment including a conventional injection molding machine, specially designed nozzle, and supercritical fluid conveying system, is used to validate the predicted results. The polymer-gas solution ejected from the injection molding machine was foamed in nozzle and cooled in the air, rather than in the mold.
