PETG extruder screw wear, output decline
Problem Phenomenon
After screw and barrel wear, the clearance increases, backflow increases and output decreases.
Cause Analysis
Long-term operation wear reduces conveying efficiency, and excessive clearance increases backflow.
Solution
Regularly measure the screw-barrel clearance; replace worn parts; use wear-resistant material screws.
Key Takeaway
PETG processing equipment wear is progressive and requires regular maintenance.
