Symptoms

The injection molding machine reports a melt quality alarm. The melt shows signs of incomplete plasticization.

Possible Causes

  • Barrel temperature too low for the material
  • Screw speed too low for adequate mixing
  • Residence time too short for full melting

Troubleshooting Steps

  1. Step 1: Verify all barrel zone temperatures are at setpoint
    Temperatures match the material spec
  2. Step 2: Adjust the screw speed for adequate mixing
    Screw speed provides uniform melt
  3. Step 3: Increase the residence time if needed
    Melt is fully plasticized and uniform

How to Reset

To reset: Resolve the melt quality issue, then clear the alarm.
