Abstract

This study addresses the challenges in die design for extruding multi-lumen tubes, which have small diameters and complex cross-sectional geometries. We present a method to utilize inverse extrusion simulation for designing extrusion dies specifically adapted to the intricate geometries. Specifically, the target geometry consists of one main and three sub lumens. Practical extrusion conditions with drawing are applied as boundary conditions in the simulation. The die geometry is designed through inverse extrusion simulation and subsequently validated via direct extrusion simulation. The predicted extrudate is well matched to the target geometry. The inverse extrusion simulation is the powerful and effective method to design extrusion dies for multi-lumen tubes with complex cross- sectional geometries.
