塑料注射成型熔融过程中的固相破碎现象

Solid-bed Break-up in Injection Moulding

注射成型熔融过程的不均匀性直接影响注射制品的质量 ,固相破碎现象是熔融过程不均匀的一个重要表现。通过自行开发的可视化实验装置 ,首次对注射熔融过程后期的固相破碎现象进行了系统的观察 。

Uniformity in polymer melting in the screw-barrel system has very important influences on the quality of injection molded products,and solid-bed break-up phenomenon is a key factor affecting the uniformity of melting.An experimental study on injection plastication is conducted in a visual barrel system.Solid-bed break-up phenomenon is observed and analysized under different processing conditions.
