1. When removing residual material from the barrel, screw, and mold, only bamboo or copper tools may be used to scrape off the adhering material; copper tools are prohibited for this purpose. Heating the screw with an open flame to remove residual material is also strictly forbidden. Plastic pelletizing machine 2. The idle running time of the screw inside the barrel must not exceed 2–3 minutes. Plastic pelletizing machine 3. Before starting production, the barrel and molding die must undergo a heating and temperature‑stabilization period of at least the specified duration; feeding material under conditions below the raw material’s plasticization temperature is not permitted.

3. Prior to feeding material into the production process, the barrel and the molding die must be held at a constant temperature for a period no shorter than the specified heating time; feeding material and commencing production at temperatures below the material’s plasticization range is prohibited.

4. Start the screw at low speed, and only after it has been running at low speed for a certain period may the screw speed be gradually increased.

5. During each shift, inspect all lubrication points at least 1–2 times and replenish with sufficient lubricant; the temperature of bearing components during operation should not exceed 50°C.

6. During operation, the plastic pelletizing machine should be regularly monitored for changes in the main motor’s current. If the motor is found to be running under heavy load for an extended period, it must be stopped immediately to identify the cause of the fault; production may resume only after the issue has been resolved.

7. After the barrel has been heated and brought to a constant temperature for the first time, tighten the mounting bolts that secure the barrel to the machine base once more.

8. When installing the screw and the mold pull‑rod, thoroughly clean all mating surfaces. Apply a thin layer of molybdenum disulfide or silicone oil to the fastening bolts to facilitate disassembly under high‑temperature conditions. Do not strike the working surfaces of any components with a heavy hammer during assembly or disassembly; if necessary, place a hardwood block beneath the component and use a hand hammer to tap the hardwood for removal.
