In the daily operation of small extruder, the host current instability has become one of the common failures. The following is a detailed introduction to the causes and elimination methods of this failure:

        1. plastic extruder host current instability causes:

(1) Uneven feeding.

(2) Main motor bearing damage or poor lubrication.

(3) A certain section of the heater fails to heat.

(4) Screw adjustment pad is not correct, or the phase is not correct, element interference.

        2. plastic extruder host current instability treatment method:
