Polymer processing is a high-energy process operation, and screw machinery is widespread applied to the polymer processing, such as screw extruders, screw injection molding machine and so on. The screw plasticating and conveying equipments based on shear rheology are generally adopted in polymer processing, in which materiels are dominated by shear stress. Therefore, there are some ubiquity disadvantages of the current methods of polymer materials processing, such as long thermo-mechanical, high energy consumption, too big equipment structure, and dependence on material properties.

加热管高分子材料成型加工是高能耗过程作业，目前普遍采用螺杆机械，如螺杆挤出机、螺杆注射机等，在螺杆机械中物料塑化输运主要是靠螺杆旋转时对物料的拖曳作用，固体输送为摩擦拖曳，熔体输送为粘性拖曳，物料的速度梯度与其流动和变形方向垂直，这种流动与变形受剪切应力支配，所以当前的高分子材料加工方法普遍存在物料塑化输运所经历的热机械历程长、能耗高、设备结构大、对物料特性依赖性强等缺陷。
