Extrusion machinery at the June NPE show in Chicago showed inventive ways to get more out of your floorspace and materials. One approach is to double output with conventional asynchronous AC motors on direct-drive, high-output extruders instead of more expensive synchronous torque motors. Another is new microlayer feedblocks and dies that can make films with higher properties for the same cost in materials. Also shown were a bunch of relatively inexpensive ways to improve efficiency.
In compounding, there was a novel corotating conical twin-screw machine, an unusual lab line for starch-resin compounding, and new ways to improving corrosion and wear resistance. ...
