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 ...

A coupled extrusion and in-situ UV curing method enables high-precision polymer-derived ceramic 3D printing with fewer ...

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 ...

Reactive processing in polymer extrusion harnesses the extruder as a continuous reactor, enabling in situ chemical modification of polymers while they are conveyed and melted. By integrating ...

Extrusion using a gear pump is useful in production processes where temperatures must remain low, for example in the automotive industry to produce car tires. At too high temperatures, material ...

It all began with a show-stopping demonstration that wowed audiences in the manufacturing world. It was at the International Manufacturing Technology Show in 2014 when the three-dimensional printing ...

Researchers propose a novel process paradigm of photopolymerization-extrusion coupled molding targeting the 3D printing of ...

Melt viscosity is regarded as a key quality indicator of the polymer melt in polymer extrusion processes. However, limitations such as disturbances to the melt flow and measurement delays of the ...

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 ...

With its diverse portfolio of polymer testing and sensing equipment, Dynisco is bringing rheology to the masses. Rheology is the investigation of the ­flow and deformation behavior of materials when ...
