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 ...

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 ...

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 ...

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 ...

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 ...

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) ...

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 ...

With its diverse portfolio of polymer testing and sensing equipment, Dynisco is bringing rheology to the masses. Rheology is the investigation of the ­flow and deformation behavior of materials when ...

A new invention from the Department of Energy's Pacific Northwest National Laboratory (PNNL) could soon help manufacturers ...

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 ...

It all began with a show-stopping demonstration that wowed audiences in the manufacturing world. It was at the International Manufacturing Technology Show in 2014 when the three-dimensional printing ...
