Parametric Modeling and Finite Element Analysis of the Extruder Key Components Based on Pro/E and ANSYS

The extruder key components consist of extrusion-screw, sleeve and nozzle. Its structure and size decides extrusion effects of the extruder, even to the capability of the whole machine. In this paper, the 3D entity modeling of the extruder key components were established by using the parametric design software of Pro/Engineer, then it was transferred into data that will be used in finite element analysis. The stress analysis was carried out by ANSYS which software of finite element analysis. The results showed that strength of the extrusion-screw, sleeve and nozzle meet the design requirements. Parametric modeling and finite element analysis was the effective way for optimal design of the extruder.
