When a special pin gate, called twin-gate, was applied in mold design, a kind of flow called self-interference flow (SIF) will be formed in cavity during injection molding process, which can control the aggregated structure of polymer and enhance the impact strength of product.
采用特殊的孪浇口设计可以产生一种所谓的熔体自干扰流动行为,通过这种自干扰流动可以控制聚合物的凝聚态结构,得到制品的冲击强度要大大优于一般浇口所得制品,这种型腔内的自干扰流动很难用传统的理论模拟来描述,采用传统的实验方法也很难对之有清晰的了解,而采用计算机辅助工程(CAE)技术模拟这一流动过程,使我们有可能来研究其形成及影响因素,以用于理论的建立及实际的生产。
METHODS By selecting the acceleration sensor to extract the self dithering interference of the system, which was treated as the referring signal, we used the technology of adaptive signal processing to see effect of restraining the self dithering interference.
