Product deformation during post-curing
Problem Phenomenon
PAI products warp and deform during post-curing heat treatment
Cause Analysis
Stress release and curing shrinkage during post-curing; heating rate too fast
Solution
Place the product on a sizing fixture for post-curing; strictly control the heating rate <3°C/min
Key Takeaway
Deformation during post-curing needs to be controlled by fixtures and slow heating
