Picture of piston extruder This instrument is a computer controlled, piston-driven extruder for polymer melts, polymer solutions, or more generally, any kind of highly viscous fluid. The apparatus is particularly useful for the production of miniature size samples of fibers, without the need for optimization of continuous extrusion parameters. The extrusion speed (piston downwards speed) can be precisely controlled from 0.01 mm/min to 100 mm/min. The maximum volume of the standard barrel is 8 cc and it is temperature controlled to 400°C. Several dies are available for fiber spinning applications.
There are two additional optional barrels which hold 5 cc and 10 cc plastic syringes to process highly corrosive fluids at low temperatures. A specialty alloy barrel is also available for processing corrosive melts.
The base instrument was designed to accommodate several expansions which will enhance its use and value. These additions will include a single screw extruder attachment, and a capillary rheometer module.
