American Leistritz Extruder Corp. has introduced a Nano-16 twin-screw extruder that — as the “nano” name implies — simulates the continuous extrusion process for tiny batches of 20-100 grams.
The Nano-16 comes with a micro¼plunger feeder. Other features include segmented screws and barrels, a stainless-steel process section and an advanced package for control and data acquisition.
Leistritz claims the extruder has the lowest free volume available for a twin-screw extruder that is scalable to production- class machinery.
The patent-pending micro¼plunger feeder is a piston that slides within a stainless-steel tube filled with a batch of material. A screw pushes the piston upwards for precision feeding at extremely low rates, according to the company.
