Dynamic Temperature and Pressure Measurement in Polymer Processing
The use of a fast responding infrared thermometer enables to measure the mass temperature across the screw channel and the resultant profile over the screw length during the plasticizing process. With a response time of 10 milliseconds this IR-Thermometer is more than 1000 times faster than conventional thermometers. Furthermore, the use of fiber-optical pressure sensors allows the measurement of the pressure profile in the feeding across the screw channel without being destroyed. Thus, the possibility is generated to measure the solid bed width in this section. Hence, the melting behaviour can be analysed.

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.
