1. Apply high-temperature anti-corrosion paste evenly to the threads of the bolts and the ribbed surface of the screw heads to prevent them from being unable to be tightened in the future.
2. Confirmation of screw model.
3. Install the screw head and confirm that the front and rear end faces of the check ring interface match the screw fitting end face.
4. Note that when installing the screw into the material barrel, the check ring should be gently pushed inward with your hand to avoid the check ring hanging on the end face of the material barrel.
5. Note that the tightening direction of the screw head is counterclockwise. (Anti ribbed)
6. The screws must be bolts with a strength level of 12.9, and the threaded surface of the bolts should be coated with high-temperature anti-corrosion paste. Hua Hong's answer
7. The screws of the front flange and the material cylinder must be tightened symmetrically and evenly.
8. The cooling system of the screw barrel of the injection molding machine should be cleaned thoroughly to ensure smoothness. Pay attention to the correct use of raw material tape and wrap it around the process plug.
9. Install the inlet and outlet water joints of the screw barrel of the injection molding machine and conduct a water pressure test, ensuring no water leakage at a pressure of 0.8Mpa.
10. Installation precautions for heating coils: The wire core should not be exposed, the plastic skin should not be compressed, and the screws should be tightened.
11. Two people must cooperate in the disassembly and assembly of the screw barrel component of the injection molding machine, and they must remind each other to pay attention to safety.
