use a reverse barrel profile. remove hopper magnets. allow 4 - 5 shots to properly disperse the conductive fibers. the surface finish should have a silver streaking appearance, not clumps.
use a reverse barrel profile. to maximize fiber length, the following injection barrel, screw, and tip designs should be followed. l/d ratio 16/1 - 22/1, compression ratio 2:1, flight depth 0.200 in (5 mm) minimum, in feed section, screw diameter 0.65 - 0
