Numerical Investigation of Aluminum Extrusion of Feeder and Porthole Dies for Solid Profiles with Massive Wall Thickness Variation

Design of extrusion dies for complex solid profiles with varying wall thickness to ensure the flow balance in the extrudate is difficult. The type of dies and their structure, which directly affect the quality of the extruded product, are significantly influenced by experience of the designer. In th...
