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 ...

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 ...

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 ...

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 ...

Monofilament, including drawn fiber, is extruded from molten polymer resin materials. These resins include very-long-chain polymer molecules. In the melt phase, these molecules are arranged in a ...

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 ...
