Cause:
Excessively high temperature can lead to overly fluid plastic melt, resulting in unstable film and causing tube deviation.
Solution: Appropriately lower the temperature of the body and the die.
Cause:
High temperature of the die connector affects the flow and stability of the melt, leading to tube deviation.
Solution: Appropriately lower the temperature of the die connector.
Cause:
Uneven extrusion results in film with varying thickness, which can cause tube deviation.
Solution: Adjust the die gap to ensure uniform extrusion and adjust the die connector temperature to stabilize the melt flow.
Cause:
If the cooling effect of the air ring is uneven, the film cools at different rates, causing tube deviation.
Solution: Check the air ring to ensure even distribution of cooling air, and appropriately adjust the position and airflow of the air ring.
Cause:
Unstable traction speed or an imbalanced traction device can cause tube deviation.
Solution: Check and adjust the traction device to ensure stable and balanced operation.
Cause:
Quality issues with raw materials, such as excessive impurities or inconsistent melting points, can also cause tube deviation.
Solution: Select higher quality raw materials and avoid using plastic with excessive impurities.
Cause:
An improperly positioned or loosely installed die can cause uneven extrusion, leading to tube deviation.
Solution: Check and adjust the die position to ensure it is securely installed and correctly positioned.
