LCP Product Gate Design
Problem Phenomenon
Gate position determines success or failure.
Cause Analysis
Gate position determines LCP molecular orientation direction, directly affecting strength, thermal expansion, and warpage; a wrong gate position cannot be compensated by machine adjustment.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
Solution
①Mold flow analysis at the gate design stage; ②align orientation direction with the main stress direction; ③keep weld lines away from stressed areas; ④compare and verify multiple schemes.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP gate design is the first decision in mold success or failure; orientation planning must precede manufacturing.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
