In the past few decades, some modified injection molding technologies aiming to fabricate highly oriented superstructure as “self-reinforcement” phase in injection molded samples, such as SCORIM, DPIM, and PVIM, have been extensively proven to be effective in improving mechanical properties of polyolefin. However, there is rare report focus on applying these technologies on reinforcing products with a more complex geometry structure until now. The vibration injection technology is currently researched at lab scale rather than wildly used in industry. Here we designed a lid-shaped part, of which the geometry structure is completely different from the rectangle or dumbbell used in the previous studies, and a novel multiflow vibration injection technology was hired to control the content of shish-kebab successfully. The self-reinforcement effect induced by shish-kebab was remarkable, indicated by the overall improvement in mechanical properties. This work gave a new insight into the practical application pro...
