Local orientation measures by infrared dichroism and thermal stress measures by dilatometric analysis of image (DAI) have made it possible to quantify the evolution of the structure versus the thickness of the injected plastic parts. The stiffness local properties on the one hand, and thermal expans
In this study cavitating flows in an injection nozzle under time-depended inlet pressure are calculated using a dispersed bubble dynamics model. The calculations confirm that a transient rise of the nozzle inlet pressure forces cavitation to recede and a sharp decrease of the injection pressure enha
This article relates to an investigation of injection moulding a new commercial polymer, an aliphatic polyketone (PK). A terpolymer and a 30% glass-filled grade were used as study materials together with an isotactic polypropylene that was used as a basis for comparison. Both conventional injection
