The Randcastle Microtruder is a single screw extrusion system for films and fibers. The screw has a 1/4-inch diameter (6.35 mm), typical amounts for one run are around 10 g. The barrel temperature is controlled indepentently by three heating zones, one extra temperature controller is responsible for the die block or fim die. For fibers, the melt is extruded vertically, films are drawn over a chill-roll horizontally. No pressure gauge or vacuum degassing is possible, the feed stock must be ground to appr. 1000 microns diameter, commercially pellets can't be fed. Feeding zone and gear plate are water cooled.
