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 ...

Equal Channel Angular Extrusion (ECAE) is a solid-state processing technique adapted from the metallurgical field to tailor the microstructure and properties of polymeric materials without altering ...

Real-time visibility into polymer melt viscosity during the extrusion process results in improved quality of the end product and minimizes material waste. However, existing monitoring technologies ...

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 ...

The global plastics industry is at a critical juncture, with mounting pressure to reduce waste and embrace sustainable practices. At the heart of this transformation lies extrusion technology — 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 ...

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 ...

Angel investors understand the high stakes of funding new technologies. The journey is fraught with financial, technical and market risks—but when a groundbreaking well-designed innovation meets the ...

On the right, a vacuum-assisted extrusion is leveraged in large-scale additive manufacturing to reduce porosity in printed parts. The inset image, on the left, is a close-up of the vacuum-assisted ...
