PESU Demolding Sticking
Problem Phenomenon
PESU high-temperature mold demolding, mold sticking and ejection management.
Cause Analysis
PESU mold 149~163℃, high demolding temperature; mold sticking risk; ejection system; surface treatment; mold 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; ④cautious use of mold release agent; ⑤monitoring and adjustment.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PESU 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
