AMERICAN Kuhne has launched a new single screw extruder design. After working closely with customers in both industrial and medical markets, the company now offers a wide range of modular production extruders that enable barrel and screw modules to be changed quickly and easily. For applications that are very sensitive to contamination and/or resin changes, the ability to easily separate the screw and barrel from a machine and replace it with a clean ‘on-deck’ module can be critical to both product purity and profitability. For processors that run a wide range of product sizes and throughput, the ability to change the extruder size by quickly switching to a different diameter and/or length screw and barrel provides a high level of processing and production scheduling versatility. The extruders are available in four different styles. The small modular extruders can be changed by hand, and range from 0.5" to 1.25". The medium size designs include barrel modules mounted on wheels,

and range from 1" to 1.75". The large barrel modules include precision sub-bases with built-in fork pockets, and range from 1.75" to 3.5". The extra large size ranges from 3" to 4". Metric extruder sizes and complete turnkey tubing and pipe systems are also available. American Kuhne has supplied over 1,200 extruders worldwide, and supplies single
