New Frontier for Single Screw R&D: Mixing & Melting by Extensional Shear
Extensional shear generally has been associated only with twin-screw extruders. However, I am now convinced it can be done with a single moving force (screw) by changing the geometry of the flow field perpendicular to the direction of flow.

Study May Boost Prospects For Single-Screw ‘Elongator’
Dow Chemical Co., Midland, Mich., weighed in at last year’s SPE ANTEC with a paper discussing results of experiments they conducted on a novel elongational mixing device developed by Randcastle Extrusion Systems

Single Screw Extrudes Rigid PVC Dryblend
A 2.5-in. diam. single screw with two Elongator mixing sections, built by Randcastle Extrusion Systems Inc., Cedar Grove, N.J., can process rigid PVC dryblend at 70 rpm for 150-lb/hr output.

Extrude Rigid PVC Three Times Faster
A new mixing section called the Elongator from Randcastle Extrusion Systems Inc., Cedar Grove, N.J., is a spiral version of the company's fl uted Recirculator mixing section.

Reprocess Barrier Film Scrap into Sheet
In tests late last year, a 0.75-in. single-screw lab extruder from Randcastle Extrusion Systems Inc., Cedar Grove, N.J., reprocessed five-layer PP/EVOH barrier film into 30-mil monolayer sheet, in which the EVOH was dispersed into sub-micron-size domains in the PP matrix.

NPE 2006 News Wrap-Up: Compounding
Much of the compounding news at the NPE Show in Chicago in June ad-dressed the growing trend among extrusion processors to become compounders.

New Mixing Screw Grows Up
Randcastle Extrusion Systems Inc., Cedar Grove, N.J., has sold the first commercial-scale Recirculator Screw, a single screw with a novel intensive-mixing section (U.S.

NPE Newsfinder: Extrusion
NPE will show higher outputs of practically everything, as advances in grooved feeds, servo drives, screw torque, mixing screws, dies, and downstream cooling, cutting, and handling make everything run faster.
