1. Do not start the machine when the screw has not reached the preset temperature.
2. Prevent metal fragments and debris from falling into the hopper. If processing recycled materials, a magnetic hopper must be added to prevent iron filings from entering the barrel.
3. When using anti-saliva, make sure that the plastic in the barrel is completely melted to avoid damaging the transmission system parts when the screw retreats.
4. When using new plastic, the remaining material on the screw should be cleaned.
5. When the temperature of the molten plastic is normal but black spots or discoloration are constantly found in the molten plastic, the rubber screw should be checked.
6. During processing, try to make the material plasticized evenly, do not let metal foreign matter mix into the material, and reduce the torque of the screw rotation.
