The best compounding & extrusion equipment is only as good as your choice of feeder keeping up with technology EXTRUSION Compact Coex Line for Medical Tubing A new coextrusion line from American Kuhne, Ashaway, R.I., features one 12-mm and two 16-mm microextruders Booth 3291 MECHATRONĀ® Gravimetric & Volumetric Feeders Feeds TiO2, wood flour, resins, fibers, colors, and many others. Feed rates from .002 to 1,100 cu. ft./hr. Complete disassembly from non-process side for easy maintenance, and quick product changeover. All components accessible from rear of feeder. Easy removal of Helix and Quill. mounted on a common base. Aimed at ultra- low-volume medical micro-tubing, the ma- chines are design to operate at what the supplier calls "comfortable screw speeds" to avoid polymer degradation. Kuhne microex- truders include pressure control and servo drive systems. Melt pumps are optional. The line was part of American Kuhne's display at NPE2012 in Orlando, Fla., last month.

Called the Ultra Micro Film line, the system features an Release band clamp, slide out feed hopper. For the best plastics feeding solutions, call: (800) 558-0184 8-mm, 30:1 L/D extruder with a conical screw that reportedly can accommo- date larger pellets than other tiny lab extruders (though still smaller than con- ventional pellets). The die is an unusual combination of spiral and spider design with a die-lip diam. of 20 mm. The 150-mm wide film tower can produce lay- flats up 90 mm. The air ring has an adjust- able lip opening and is sup- plied by a built-in variable- speed turbo blower. Nip-rolls are driven with a variable- speed DC motor and open/ close pneumatically. The tower comes with a film inspection lamp. The line also features a two-station tension winder. +66 2-709 6959 t MBCUFDIFOHJOFFSJOH DPN Schenck AccuRate is a unit of Schenck Process.
