Extrusion is a process widely used in the polymer processing industry. It involves pushing material through a die with a specific cross-sectional shape, resulting in products like profiles, thin ...

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 ...

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 ...

Reactive processing in polymer extrusion harnesses the extruder as a continuous reactor, enabling in situ chemical modification of polymers while they are conveyed and melted. By integrating ...

While countless tubes are extruded or injection molded each year, these manufacturing techniques are neither the most optimal nor the most cost-effective methods available to medical device ...

Editor?s note: Chris Rauwendaal is a designer, consultant, and seminar instructor who has written extensively on process engineering and extrusion topics. Part 1 of this article (PM&A Nov./Dec. 2002) ...

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 ...

Researchers propose a novel process paradigm of photopolymerization-extrusion coupled molding targeting the 3D printing of ...

Editor?s note: The author, Donald E. De Laney, a consultant in polymer process rheology, worked with GE for 17 years and has worked with Dynisco over the past eight years. The plastics compounding and ...

A coupled extrusion and in-situ UV curing method enables high-precision polymer-derived ceramic 3D printing with fewer ...

Angel investors understand the high stakes of funding new technologies. The journey is fraught with financial, technical and market risks—but when a groundbreaking well-designed innovation meets the ...
