Design of extrusion die for plastic profile using ansys polyflow software

Pepliński K., Mozer A.

Extrusion is one of the most widely used processes for polymer processing. Example: extrusion is a technique for producing film, pipe, sheet, profiles, cable and coatings in coextrusion process. The main tool used in this process for the manufacturing final shape product is die. The task of this article is to design the last part of extrusion die (die land) for plastic profile, using numerical simulation. In this paper was presented methodology of numerical simulation for the die design. A commercial computer fluid dynamics program Ansys Polyflow was used to design the die passage. The objective of the simulation is to determine the die passage that results in a balanced mass flow exiting the die that closely matches the target profile. The die land shape modification with using optimization algorithm is very helpful to obtain geometry and dimension of extrudate desired profile.
