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 ...

This study presents a deep learning-based monitoring system for estimating extrusion angles in the manufacturing process of microcatheter tubes. Given the critical nature of these tubes, which are ...

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

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 ...

Optimization of the mechanical and crash properties of extruded AA6XXX automotive profiles requires detailed understanding of grain size evolution and formation of the peripheral coarse grain (PCG) ...

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 ...

In the plastics industry, twin screws are at the very heart of the extrusion process that transforms raw materials into rigid PVC pipe or profile. These highly engineered components are integral to ...

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 ...
