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 ...

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

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 ...

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 ...

Operators should watch for changes in line sound, vibration, melt appearance, surface quality, and cooling behavior.

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 ...

The advantages and disadvantages of hot-melt extrusion in solid dispersion formulations. Solid dispersions represent a promising formulation approach for overcoming today's major challenge in ...

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 ...
