PAEK insufficient crystallinity, low performance
Problem Phenomenon
The product has insufficient crystallinity, appearing translucent, with poor mechanical properties
Cause Analysis
Mold temperature <160°C causes quenching forming amorphous structure; cooling speed too fast and molecular chains have no time to arrange
Solution
Increase the mold temperature to 180-200°C; post-process at 200°C/2h to promote crystallization
Key Takeaway
PAEK crystallinity is the most important performance control indicator
