| Abstract: | This article utilized Deform-3D software to carry out the numerical simulation of the aluminium alloy rod extruding forming process. Analysis of data collected during the extruding procedure made it possible to predict the shrinkage cavity flaw of the aluminium alloy rod. Following the results of the simulation, an improvement program is proposed, including an optimized mould design. The actual production indicated that this improvement measures can solve the shrinkage cavity flaw of extruding process effectively. |
