Scientists have developed a vacuum-assisted extrusion method that reduces internal porosity -- by up to 75% -- in large-scale 3D-printed polymer parts. Large-scale additive manufacturing has been ...

You’ve got questions about extrusion, and Allan Griff has the answers. But what he didn’t have during a recent webinar on the key principles of extrusion hosted by PlasticsToday was time. Dozens of ...

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 ...

Polymers are defined as materials consisting of macromolecules that are made up of small, regularly repeating smaller subunits. The coextrusion process is a manufacturing process that uses different ...

The authors examine the influence of glass-transition temperature, melt viscosity, degradation temperature, and process settings. Hot-melt extrusion (HME) technology is prominent in the pharmaceutical ...
