Vibration processing/molding has been recently developed, in which polymer melt essentially flows or deforms under periodic stress in direct/superposed mechanical oscillation or ultrasonic vibration shear/pressure so that the flow field and some physical processes are varied.

近年来出现了振动加工成型，其实质是在机械振动、超声波的直接作用或叠加在剪切、压力流上，使聚合物熔体在周期性变化的应力下流动和变形，从而改变流场类型、强化流场强度和一些物化过程。振动会影响材料的粘度和松弛行为，所以也会影响分子扩散和剪切速率敏感的共混等过程。
