Daily maintenance of Screw Barrel of injection molding machine 
Daily maintenance of material barrel
1. Do not start the machine when the barrel screw has not reached the pre-set temperature.
2. To prevent metal fragments and debris from falling into the hopper, if processing recycled materials, a magnetic hopper needs to be added to prevent iron filings from entering the material barrel.
3. When using anti saliva, it is necessary to ensure that the plastic inside the material barrel is completely melted to avoid damaging the transmission system parts when the screw moves back.
4. When using new plastic, the remaining material from the material barrel should be cleaned thoroughly.
5. When the temperature of the molten plastic is normal but black spots or discoloration are constantly observed in the injection molded product, the screw should be checked for wear on the rubber head, rubber ring, and rubber meson.
6. When product injection molding, try to make the material plasticize evenly to reduce the transmission torque borne by the screw and increase its service life.
