1. Regularly inspect the purity of the raw materials; ensure no foreign matter such as sand particles or metal powder contaminates the material and enters the barrel. 2. Routinely check all lubrication points and replenish lubricant as needed; during operation, the temperature rise at bearing locations should not exceed 50°C. 3. Allow sufficient time for the barrel to reach a stable operating temperature; never start production with raw materials below the specified process conditions. 4. When starting the screw, use a low speed; after running for a while and confirming normal operation, gradually increase the screw speed. 5. Do not allow the screw to run idly for extended periods when the barrel is empty; idle running should not exceed 2–3 minutes. 6. Frequently monitor the ammeter reading of the screw‑driving motor.
1. Regularly inspect the purity of the raw materials; no foreign matter such as sand particles or metal powder shall be allowed to contaminate the materials and enter the barrel.
2. Regularly inspect all lubrication points and replenish the lubricant as needed; during operation, the temperature rise at bearing locations should not exceed 50°C.
3. The barrel must be adequately preheated to a constant temperature; raw materials must not be allowed to fall below the process‑specified temperature before starting production.
4. When operating the screw, start at low speed; after running for a while and confirming normal operation, gradually increase the screw speed.
5. When the barrel is empty, the screw must not be run idly for an extended period; the idle running time of the screw shall not exceed 2–3 minutes.
6. Regularly monitor the ammeter needle for fluctuations in the screw‑driven motor’s current. If the motor operates under heavy load for an extended period, stop the machine, identify the cause of the fault, and resume production only after the issue has been resolved.
7. After the barrel has been heated to the process temperature for the first time, retighten the mounting bolts that secure the barrel to the machine base.
8. When installing the mold and screw, ensure that the mating surfaces are clean and free of foreign matter. Apply a thin layer of silicone oil to the fastening bolts to facilitate disassembly. Do not strike the component surfaces with a heavy hammer during disassembly; if necessary, place a hardwood block underneath and use the hammer to tap the hardwood for removal.
