Beim Prägen wird das Werkzeug vor Beginn des Einspritzvorgangs nicht vollständig verriegelt. Die Folge ist ein größerer Fließspalt im Werkzeug. Die Kavität ist zum Ende der Füllphase nur zum Teil ausgefüllt. Erst der anschließende Prägevorgang, d.h. das langsame Zufahren der beiden Werkzeughälften, füllt die Kavität vollständig und kann dabei sogar den Nachdruck ersetzen.
Neben den reduzierten Fließwiderständen beim Spritzprägen muss auch berücksichtigt werden, dass ein größerer Fließspalt eine langsamere Fließfrontgeschwindigkeit zur Folge hat. Daraus resultieren eine geringere Schergeschwindigkeit sowie reduzierte Wandschubspannungen. Der Werkzeuginnendruck in der Füllphase kann hierbei um bis zu 90 % reduziert werden.
Der Werkzeuginnendruckverlauf zeigt nach Ende des Einspritzvorgangs zunächst einen Druckeinbruch, danach steigt der Druck durch das Zufahren des Werkzeugs wieder an. Um derartige Druckeinbrüche zu vermeiden, besteht die Möglichkeit, den Prägehub bereits während des Formfüllvorgangs zu starten und damit Bewegungen der Einspritzseite und der Schließseite simultan auszuführen. Der Zeitpunkt, an dem die simultane Prägebewegung gestartet wird, ist unabhängig von der Einspritzgeschwindigkeit mit einem definierten Füllzustand des Werkzeugs verbunden, da das Simultanprägen in Abhängigkeit von der Schneckenposition beginnt.

During injection-compression molding, the mold is not fully closed prior to the injection phase, which results in a wider flow gap in the mold. At the end of the filling phase, the cavity has been filled only partially. The subsequent compression process, i.e. the slow closing movement of both mold halves, leads to a complete filling of the cavity and can even compensate for a potential lack of holding pressure.
Injection-compression molding, however, does not only reduce the flow resistance. A widening of the flow gap also slows down the flow front velocity. The result is a lower shear rate and a reduced wall shear stress. The mold cavity pressure during the filling phase may be up to 90% lower.
The mold cavity pressure profile shows a decompression at the end of the injection phase followed by a pressure increase during mold closure. Decompression can be avoided by starting the compression stroke as early as the mold filling phase, i.e. simultaneous movements of the fixed mold half and the moving mold half. Independent of the injection speed, the starting point of the simultaneous compression movement correlates with a predefined mold filling stage, since the starting point of simultaneous compression is dependent on the position of the screw.

I specialise in translating technical articles, press releases, websites, customer publications etc. concerning all matters related to plastics and rubber engineering and all linked areas such as medical engineering or automotive engineering from German into English and vice versa. My customers are renowned members of the automotive and plastics industry. For samples of my work, you may also refer to the English content of the following websites:
www.telenet.de (Telecommunications)
www.dpg.com (Polymer processing)
www.3dse.de (Marketing)
I also translate English literature (travel literature, children's books etc.) for one of the largest publishing companies in Germany.
Extensive professional experience as an editor of polymer processing-specific publications. A list of reference clients may be supplied.
