Qualitätsregelung beim Spritzgießen (Teil 2): Adaptive, druckgeregelte Prozessführung

Abstract: Qualitätsregelung beim Spritzgießen (Teil 2): Adaptive, druckgeregelte ProzessführungAktuelle Produkte fordern höchste Präzision bei der Erfüllung von Qualitätskriterien und Schnittstellenanforderungen. Die Reproduzierung der Prozessparameter beim Spritzgießen reicht hier nicht mehr aus, um diese Anforderungen zu gewährleisten. Störungen der Prozesse sind vielfach auf Alterungs-und Konditionierungseinflüsse auf das Materialverhalten zurückzuführen. Ausgehend von einer detaillierten Materialcharakterisierung un… Show more

“…Depending on the machine’s period of use, signs of wear and tear may occur. The wear of the non-return valve has an influence on the ejection behavior [ 9 , 10 , 11 ] and the process stability [ 12 , 13 ]. A comparison of different machine types in [ 8 ] has shown that servo-electric machines can have a more precise control of the screw position, but the reproducibility of the part quality was worse [ 8 ].…”

“…The flow behavior of the melt influences the back pressure during injection, which in turn affects the position control of the screw [ 3 ]. Thus, different material types or additives such as fibers can influence machine behavior, whereby even small variations between material batches of nominally identical materials can cause significant variations [ 11 , 14 ].…”
