What is Hollow Extrusion Die Design Method about?

This paper presents an improved inverse design method for thin-walled hollow polymer extrusion dies using finite element method computational fluid dynamics (FEM-CFD) simulations. The inverse design method aims to compensate for die swell and profile distortions by modifying the die geometry. Simulation results show that the thickness of the die lip gap can be increased by decreasing the inlet flow rate, and the geometry of the die lip gap can be widened by increasing the length of the free jet.
