Quality control in injection molding (part 2): Adaptive, pressure controlled process management
Actual products demand very accurate reproduction of the defined quality criteria and interfacial criteria for following processes. The reproduction of process parameters in injection molding is no more sufficed to guarantee the quality requirements. Process disturbances are often related to aging and handling influences on the material behavior. Therefore a material characterization leads to an extended model approach to describe the rheological behavior under aging influences and the development of an adaptive, pressure controlled process management. The process influences by varying material properties are shown in a process simulation, compared to the injection molding process and compensated by the new quality control strategy.

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.
