Filling Challenges Brought by Rapid LCP Crystallization
Sorun Belirtisi
【Problem Phenomenon】Once the LCP melt cools down it solidifies immediately; filling the end of long flow paths is difficult, and the process adjustment margin is small
Neden Analizi
LCP crystallizes extremely fast; as soon as the melt front temperature drops slightly, a solidified layer forms and blocks the flow path; this characteristic brings both the advantage of short cycles and the disadvantage of a narrow filling window; Fictiv lists rapid crystallization as a core feature of LCP processing
Çözüm
Use the rapid crystallization characteristic with high-speed injection to shorten filling time; take the upper limit of mold temperature to delay front freezing; make runners and gates short and thick to reduce pressure and heat loss
Temel Çıkarım
Fast crystallization is a double-edged sword: only high-speed filling plus high mold temperature can use its benefit and avoid its harm; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
