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.
结果表明，不同角度圆锥口模挤出过程中，熔体在收敛流道受到拉伸流变，导致强烈的入口弹性效应，表现出熔体在不同角度圆锥口模挤出时有不同的挤出胀大比。
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.
结果表明，圆锥短口模挤出过程中，熔体在收敛流道受到拉伸流变，导致强烈的入口弹性效应，表现为熔体在短口模挤出时显著的挤出胀大。
