Automated optimization of flow-channels to improve the purge behavior of extrusion dies
Purge-processes are a considerable cost factor in extrusion processes. These costs are founded in huge quantities of junk material and in high costs for energy and personal. The flow channel geometry is one of the main factors of influence for purging the extrusion die. In this manuscript will be discussed, how to create a completely automated solution for the optimization of simple flow channel geometries by means of genetic algorithms to reduce the purge time. The production type and the costs are boundary condition to eliminate non-economic design proposals.
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.
