PC/ABS '2079851475616104452 warpage
Problem Phenomenon
Large flat PC/ABS products warp and deform after demolding.
Cause Analysis
The shrinkage difference between amorphous PC and semi-crystalline ABS, plus uneven mold temperature, causes warpage.
Solution
Increase mold temperature 60-80°C with uniform distribution; uniform wall thickness; optimize gates.
Key Takeaway
PC/ABS warpage is jointly caused by the shrinkage difference of the two components and uneven cooling.
