Temperature change by compression and expansion of polymer melts
The compression of polymer melts is of importance for the process management of conventional injection molding as well as for new techniques such as Compression Induced Solidification (CIS) and Expansion Injection Molding (EIM). To investigate the compression heating and expansion cooling of amorphous and semi-crystalline thermoplastics, the resulting temperature change due to slow and fast compression was measured and analysed. In addition, the experimental results were correlated to solutions of well known arithmetical approaches.

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.
