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 ...

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 ...

In past columns, I've written about measurement of the key process variables in extrusion: Melt temperature, melt pressure and motor load . . . the vital signs. However, I shouldn't assume that all of ...

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 ...

The hot melt extrusion (HME) process can be employed in the production of a wide range of pharmaceutical dosage forms, including capsules, tablets, lozenges and implants. HME is suitable for both ...

Medical tubing used in minimally invasive devices has become increasingly sophisticated. Today’s cutting-edge devices are reaching more remote regions of the human anatomy and are used to perform ...

Critical issues that should be considered when scaling up a hot-melt extrusion process. Hot-melt extrusion (HME) using twin-screw extruders (TSEs) is increasingly being used to make solid dispersions ...

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 ...
