So there I sat (we were still at port) and learnt what had originally fired my host's ambition to possess what he was pleased to call a "real, genuine, twin-screw
, double-funnelled, copper-bottomed Old Master"; it was to "go one better" than some rival legislator of pictorial proclivities.
Ahead of us floats an ancient, aluminum-patched, twin-screw
tramp of the dingiest, with no more right to the 5000-foot lane than has a horse-cart to a modern road.
Chinese firm makes SJ Series single-screw extruders, SJCZ conical twin-screw
extruders, and extruders for tri-colored straws, hollow-wall flexible pipe, dual-wall corrugated pipe, and profiles.
With the DSE 200 twin-screw
extruder, the company is said to offer a subsequent aggregate to the internal mixer specially designed for the technical rubber goods industry.
Above all, you'll see a lot of unconventional approaches to compounding that bear little resemblance to traditional mixers or twin-screw
TEM Series co-rotating, intermeshing twin-screw
technology is said to offer the highest torque-per-free-volume and the highest screw speed available in the industry.
extrusion of undried PET can produce sheet with I.
With the company's hot melt adhesive compounding extruder, continuous twin-screw
mixing is said to enhance the quality of hot melt pressure-sensitive adhesives, according to this two-page, color bulletin.
extrusion systems for rigid PVC pipe, siding and profiles including three conical and four parallel twin-screw
extruders: Con 40, BEX 54 and DSK 62 conicals; and TS 92, TS 110, TS 135 and BEX 168 parallels with 26:1 L/D.
Topics covered during this continuous mixing seminar will include the following: Continuous mixing, a challenging opportunity; theoretical considerations of the mixing process; continuous mixing of rubber - technology, economical efficiency and results; elastomeric composite produced with continuous liquid phase mixing; production and application of silica loaded powder rubber systems based on ESBR; twin-screw
rubber mixing and extrusion concepts; new developments in the extrusion and mixing technology of rubber compounds; a new single-rotor continuous mixer; optimizing the continuous mixing process of natural rubber compounds on the twin-screw
extruder; processing advantages of the extruder-gear pump system; and modern on-line control of the factory mixing process.
ZSK corotating intermeshing twin-screw
extruders in MEGAcompounder or MEGAvolume design for compounding polyolefins, engineering resins, color additive masterbatches, and blending reinforced plastics.
Additionally, reactive processing schemes often require modification or substantial revisions when transitioning to twin-screw
extrusion or when the recycled elastomer feed stock is changed.
