1. Do not start the machine when the barrel has not reached the preset temperature. Newly opened electric heating generally requires the temperature to reach the set value for 30 minutes before operating the screw.
2. If the machine stops for more than half an hour each time, it is best to close the discharge port and clean the material inside the barrel, and set insulation.
3. Prevent foreign objects from falling into the material barrel and damaging the screw and barrel. To prevent metal fragments and debris from falling into the hopper, if processing recycled materials, a magnetic hopper should be added to prevent iron filings from entering the barrel.
4. When using anti saliva, it is important to ensure that the plastic inside the barrel is completely melted to prevent damage to the transmission system components when the screw moves back.
5. Avoid screw idling, slipping, and other phenomena.
6. When using new plastic, the remaining material from the barrel should be cleaned thoroughly. When using materials such as POM, PVC, PA+GF, etc., try to minimize the degradation of raw materials. After shutdown, rinse thoroughly with ABS and other water outlet materials in a timely manner.
7. Avoid mixing POM and PVC into the barrel at the same time, as it will react at the melting temperature and cause serious industrial accidents.
8. When the temperature of the molten plastic is normal but black spots or discoloration are continuously observed, the screw check ring (through rubber ring, meson) should be checked for damage.
