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 ...

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 ...

Editor?s note: The author, Donald E. De Laney, a consultant in polymer process rheology, worked with GE for 17 years and has worked with Dynisco over the past eight years. The plastics compounding and ...

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 ...

Polyfuze Graphics has introduced a technology that “fuses” permanent labels into the plastic during the extrusion process, eliminating the risk of peeling or detachment. The innovation offers ...

Extrusion is a continuous processing technique in which polymeric materials are conveyed, melted and homogenised as they are forced through a die to form strands, sheets or complex profiles. Key to ...

Polymer extrusion is a cornerstone of modern manufacturing, employed to produce films, pipes, profiles and advanced composites at industrial scale. The mechanical properties of extruded ...

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 ...

(MENAFN- EIN Presswire) EINPresswire/ -- WUXI, China,June 17, 2026 - The Chinese plastic extrusion machinery sector continues to evolve as manufacturers invest in tailored solutions for polymer ...

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 ...

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 ...
