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 should be added to prevent iron filings from entering the barrel.
3. 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.
4. When using new plastic, the remaining material from the barrel should be cleaned thoroughly.
5. When the temperature of the molten plastic is normal but black spots or discoloration are continuously 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 plasticize the material evenly to reduce the transmission torque borne by the screw and increase its service life.
