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 ...

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 ...

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 ...

On the right, a vacuum-assisted extrusion is leveraged in large-scale additive manufacturing to reduce porosity in printed parts. The inset image, on the left, is a close-up of the vacuum-assisted ...

Increasingly smaller medical devices require tighter tolerances that make extrusion process control more difficult. Photos courtesy of TEEL PLASTICS INC. As medical devices get smaller and tolerances ...

Polymer rheology—the study of how polymers flow and deform—is key to achieving consistent quality in manufacturing and 3D printing. From injection molding to extrusion, understanding viscosity, ...
