What are the common faults of the IC tube extruder head?

1. IC tube extruder head discharge is not smooth or blocked

1, the cause:

      (1) A certain section of the heater does not work, and the material is not plasticized.

     (2) The operating temperature setting is low, or the molecular weight distribution of the plastic is wide and unstable.

     (3) There may be foreign matter that is not easily melted.

2, the processing method:

     (1) Check the heater and replace if necessary.

     (2) Verify the set temperature of each section and, if necessary, negotiate with the technician to increase the temperature setting.

     (3) Clean and inspect the extrusion system and the machine head.

2. The main power start current is too high

1, the cause:

     (1) The heating time is insufficient and the torque is large.

     (2) A certain heater does not work.

2, the processing method:

      (1) Apply the hand truck when driving. If it is not easy, extend the heating time or check whether the heaters are working properly.

3. The main motor makes an abnormal sound

1, the cause:

      (1) The main motor bearing is damaged.

      (2) A thyristor in the main motor thyristor rectifier circuit is damaged.

2, the processing method:

     (1) Replace the main motor bearing.

     (2) Check the thyristor rectifier circuit and replace the thyristor component if necessary.
