Abstract：

Based on HyperXtrude software, the finite element analyses of extrusion process for aluminum profile were conducted by butterfly die and diffluent compound die respectively, and the cloud diagrams of extrusion temperature and extrusion speed for two groups of dies were obtained. However, the uniformity of extrusion temperature and extrusion speed affected the quality of profiles, and the quality of profiles was guaranteed only within the difference rate of extrusion temperature and extrusion speed of 5%. Furthermore, the extrusion temperature difference rates are 1.10% and 1.26% respectively, and the extrusion speed difference rates are 1.76% and 1.18% respectively in the extrusion process simulation experiment of diffluent compound die and butterfly die, which could ensure the quality of profiles. The higher the extrusion speed is, the higher the extrusion efficiency is, and the lower the energy consumption of extruder is. The results show that the butterfly die can increase the extrusion speed by 24.66% which greatly improves the production efficiency of extruder and reduces the energy consumption of aluminum profile production comparied with the diffluent compound die.
