Towards Shape Optimization of Extrusion Dies Using Finite Elements
The final shape of profile extrusion dies is determined in an empirical process; a die designer iteratively modifies the shape until the quality restrictions of the extrudate are satisfied. Fluid flow simulations can aid in quickly judging different designs but cannot eliminate the empirical nature of the process. This can be changed by a framework that couples fluid flow simulations with a mathematical optimization algorithm. Without further user interaction, the framework computes the die's optimal shape. The functionality of the framework is demonstrated at the shape of 2D models, these are optimized aiming at a homogeneous velocity distribution at the outlet.

The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
