Extrusion is one of the most versatile and economical process for making long rubber profile. Die swell is one of the inherent phenomena of rubbers especially during extrusion. For geometries of the profiles which are non-symmetrical or complexly shaped, the extradite changes in terms of the dimension as well as shape, leading towards complexity in the study of die swell behavior of the rubber compound. The rheology depends on the various parameters such as the geometry of the die, processing parameter, rheological properties, and the thermal parameter of the material. It also relies heavily on the thermal and rheological boundary conditions. Consequently, a large instability occurs during processing. The aim of the present study is to visualize the fluid flow behavior of the compound during processing using the finite element method. The various challenging complex profile shapes which are used to manufacture automotive parts can be studied easily by using the proper material parameters as it quickly generates an indicated set of results. This will help to increase the production efficiency of the extrudate profile by reducing the traditional prototype trial, and error method of manufacturing extrusion die for getting the desired shape of the product.
