PPSU demolding mold sticking
Problem Phenomenon
PPSU high-temperature mold demolding; mold sticking and ejection management.
Cause Analysis
PPSU mold 149~163℃ demolding temperature is high; mold sticking risk; ejection system; surface treatment; release agent.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Demolding temperature management; ②ejection optimization; ③surface treatment; ④careful use of release agent; ⑤monitoring adjustment.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPSU demolding is a high-temperature challenge; system and surface treatment are equally important; monitoring prevents defects.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
