Abstract: The self-designed physical micro foam injection molding FoamPro screw, compared with
existing products, has higher plasticization efficiency and comparable foaming effect through experimental
testing and simulation verification of multiple materials, and can be used for commercial applications.
Key words: physical microfoam injection molding; FoamPro screw; higher plasticizing efficiency;
comparable foaming effect
