PETG nozzle and mold poor alignment
Problem Phenomenon
Misalignment between the nozzle and the mold sprue bushing causes material leakage, gate abnormality or mold damage.
Cause Analysis
The injection unit position is not correct and the nozzle is not concentric with the sprue bushing, and deviation occurs after long-term use.
Solution
Adjust the injection unit to ensure the nozzle is concentric with the sprue bushing; regularly check the alignment condition.
Key Takeaway
PETG injection equipment alignment accuracy affects molding stability and mold life.
