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 prospect of vibration injection technology.

羊肉串含量的增加引起聚丙烯盖状样品的自增强：振动注射技术的实际应用

在过去的几十年中，一些旨在将高度定向的上部结构制造为注塑样品中的“自增强”相的改良注塑技术（例如SCORIM，DPIM和PVIM）已被广泛证明可有效改善材料的机械性能。聚烯烃。但是，到目前为止，很少有报道将这些技术应用于具有更复杂几何结构的增强产品。振动注入技术目前正在实验室规模研究，而不是在工业中广泛使用。在这里，我们设计了一个盖形部件，其几何结构与先前研究中使用的矩形或哑铃完全不同，并采用了一种新颖的多流振动注入技术来成功控制烤肉串的含量。烤羊肉串引起的自我增强作用非常显着，机械性能的总体改善表明了这一点。这项工作为振动注入技术的实际应用前景提供了新的见解。
