Extrusion and blow molding process: the amount is about 1.5-2 times the capacity of the barrel

Standard Cleaning Procedure (SOP)

① Preparation Stage - Empty the previous production material in the feed pipe - Clean the material outlet and surrounding residue - Ensure the equipment and environment are free of foreign objects to avoid secondary contamination ② Feeding and Setting - Set the temperature to the normal processing temperature for the subsequent production material, not exceeding 320°C - Add the corresponding amount of screw cleaner to the material outlet - Manually inject the material when the set temperature is reached - Keep the screw measurement at 60%-80% of the total amount ③ Routine Color Cleaning - Properly increase back pressure - Repeatedly inject material at high and low speeds - Manually run empty for 5-10 minutes, continuously discharging old material and cleaning material - Continue until the discharged material is basically stable ④ Deep Carbon Cleaning - After adding the cleaning material, appropriately increase the temperature by 10-20°C - Manually run empty 3 times, pause for 3-5 minutes, then cycle empty - Repeat the process 2-3 times until the cleaning material is completely discharged from the screw ⑤ Finishing and Restoring Production - Add the target production material and manually run empty 3-4 times - Observe that the discharge color is stable, then proceed with normal production Cleaning Completion Standards: - Discharge color is stable and consistent - No obvious black spots or carbonized material - No residue in the mold or runner - Meets the standard and can directly resume production

Notice

- Avoid foreign objects entering the hopper during the cleaning process - The processing temperature should not exceed 320 degrees - It is recommended to use manual mode or slow injection molding operation - When switching between different materials, it is recommended to appropriately extend the cleaning time
