Advanced Extruder Technologies (AET), Elk Grove Village, Ill., has introduced what is thought to be the fi rst single-screw compounding extruder with a grooved barrel. The axial grooves are said to improve mixing, raise output, and allow material to run at lower temperatures. AET built its fi rst axially grooved barrel more than three years ago for a 28:1 extruder running fi eld trials with polyolefi ns. AET has since developed four types of grooves with different depths and pitches, suited to different materials. Grooves can run for all or part of the barrel length. The barrels are water- or oil-cooled and have grooved feed sections. Tel: (847) 238-9651 . www.aetextruder.com
