Abstract:

This article introduced the definition and advantages of microcellular foamed plastics and compared the two microcellular foaming injection molding processes, including physical microcellular foaming and chemical microcellular foaming. The latest research progress in microcellular foam injection molding technology was introduced in terms of process optimization, mold opening secondary foaming, surface quality improvement, and mechanical performance prediction. Finally, the future research direction of microcellular foam injection molding technology was prospected.

Key words: microcellular injection, molding, lightweight, process optimization, surface quality
