The results show that the extensional flow of melt in convergent die results in intense entrance elastic effect and distinct extrusion swell in conical die with different angles.
The effect of the technology and equipment, such as the structure and dimension of die plates, the extrusion conditions and so on, on the die swell and shrinkage of tread extrudate was described.
