Polymer extrusion is a cornerstone of modern manufacturing, employed to produce films, pipes, profiles and advanced composites at industrial scale. The mechanical properties of extruded ...

Scientists at Oak Ridge National Laboratory have developed a vacuum-assisted extrusion method that reduces internal porosity—by up to 75%—in large-scale 3D-printed polymer parts. The paper is ...

Extrusion is a continuous processing technique in which polymeric materials are conveyed, melted and homogenised as they are forced through a die to form strands, sheets or complex profiles. Key to ...

Changes such as the transition from crystalline to amorphous phases or shifts in vibrational modes can be used to customize the end-polymer's mechanical, thermal, and optical properties to specific ...

Real-time visibility into polymer melt viscosity during the extrusion process results in improved quality of the end product and minimizes material waste. However, existing monitoring technologies ...
