WebDec 28, 2016 · In this study, the porthole die extrusion experiments were carried out to study the welding quality of longitudinal weld seams (L-seam) of high-strength 7075 aluminum alloy. The differences in microstructure and mechanical properties of L-seams under various extrusion temperatures and at different positions along extrusion direction were discussed. WebIn this study, porthole die used for extrusion of a solid heatsink profile with wall thickness variation ratio up to 15.3 was designed using finite element (FE) simulations. To improve the flow balance in the die, a design approach was introduced to find the appropriate die structure, which includes the porthole and pocket geometry correction, the bearing length …
