振动技术在注射成型中的应用

Application of Oscillation Technology in Injection Molding

介绍了振动技术在注射成型中的应用，描述了模腔内振动剪切流动的作用机理。实验研究表明，通过振动的作用能提高注射制品的拉伸强度。利用螺杆振动技术而制备的ＰＰ、ＨＤＰＥ和ＰＳ注射制品的拉伸强度分别提高１８．３％、２２％和１６％。

The application of oscillation technology in injection molding is introduced,and the mechanism of oscillatory shear flow in the cavity is described.The experimental results indicate that oscillation can enhance the tensile strength of molded parts.Using the oscillation of screw,the tensile strength of injection molded PP,HDPE and PS parts is increased by 18.3 %,22 % and 16 % respectively.
