for analogue simulation, which has been applied to the simulation of extrusion processes of aluminium profile. In this numerical experiment, a porthole die was designed to produce a complex section... and is affected by process variables and die shapes. Porthole die extrusion has a great advantage in the production of hollow sections, which is difficult to product by conventional extrusion. A greater......
