Troubleshooting with barrel zones
Vol. 19 #1, Feb. 1992
If a barrel zone on an extruder constantly overrides or requires too much cooling to maintain a set point, it may be that the melting is being concentrated in that section. This can either be because of screw design or improper barrel profile.
A solution is to increase the temperature of the proceeding zone to increase the melting prior to the "Hot Zone".
