Hello all, just looking to see if i'm not the only one having these issues.
PROBLEM:
Glass filled nylons 13 to 33 % in hot runner systems.
I don't think I've ever been able to run these jobs without cranking hot runner zones up to 650 - 700° range.
Unfilled nylons not so bad, but I'm always being questioned from tooling and qc asking Why are zones so high?
It gets frustrating because It's hard for them to understand that the only way i can get plastic through this mold without freezing off is to do this. the nozzles are pretty small on these, as some have diverter tips on them. side note: running mold temp at 185°
Also we have UR robot taking about 10 seconds to load inserts in mold, i know this does not help. Any good ideas or insights?
