LCP Product Gate Design
Fenómeno del problema
Gate position determines success or failure.
Análisis de la causa
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
Solución
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
Conclusión clave
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
