1. Screw wear:
Cause: hard impurities mixed in the material, screw speed is too high, material lubricity is poor, etc.
Solution: clean the material, reduce the screw speed, add lubricant.
2. Barrel wear:
Cause: hard particles in the material, poor barrel material, etc.
Solution: replace the barrel, clean the impurities in the material.
3. Motor overload:
Cause: screw speed is too high, material is blocked, motor power is insufficient, etc.
Solution: reduce the screw speed, clean the blocked material, check the motor power.
4. Heater failure:
Cause: heating element damage, temperature controller failure, etc.
Solution: replace the heating element and calibrate the temperature controller.
