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

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 ...

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 ...

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 ...

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 ...

The Charlotte, N.C.-based Polymers Center of Excellence installed its sixth extrusion line and is planning a 12,000-square-foot addition as it adds capabilities and capacity for instruction, research ...

In response to growing environmental concerns and the urgent need for sustainable practices, the upcycling of post-consumer and reprocessed plastics has become a critical focus. This webinar will ...

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 ...

Valued for their ability to safely degrade in the body over time, bioabsorbable materials have had a profound impact on medical device development in recent years. In addition to their widespread use ...

Commercial purge compounds (CPCs) were originally designed and marketed to the injection molding industry, which remains the dominant process for CPC usage. Today injection molders are aware of the ...

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 ...
