Common equipment failures and troubleshooting methods in the production process of the PP corrugated hollow sheet machine
| Failures of machine | Reason | Solution |
| Impurities appear on the surface of the sheet | Broken filter | change filter |
| The whereabouts of the product at the exit of the mold | Mold temperature is too high | Adjust the temperature in system,cooling down the temperature |
| Patterns appear on the surface of the sheet | Mold temperature is too low | Ajust the temperature in system, elevated temperature |
| partial suction rupture | a. Mold temperature is too highb. Excessive suctionc. The air volume of the air knife is small | 1.Cool down the corresponding part of the mold2. Reduce suction3. Increase the air volume |
| Sheet is not flat | a. Uneven mold temperatureb. Uneven mold flowc. Uneven die gapd.The temperature difference between the top and bottom of the oven | 1.Adjust the corresponding mold temperature2.Adjust the flow of the choke block3. Adjust the die gap4.Adjust the oven temperature |
| Inconsistent square size | a. The air path is blockedb. The air volume is too small or too large | 1. Clean up the air path2. Adjust the airflow |
