AEPDS warpage deformation
Problem Phenomenon
AEPDS product warpage, amorphous but stress and uneven cooling.
Cause Analysis
AEPDS amorphous material; but internal stress and uneven cooling still cause warpage; wall thickness difference; uneven mold temperature; improper holding pressure.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Uniform mold temperature; ②holding pressure optimization; ③wall thickness design; ④cooling management; ⑤stress release.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
AEPDS warpage management focuses on stress and cooling; uniformity is the core; process and structure are both important.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
