LCP Injection Cycle Optimization and Rapid Crystallization Utilization
Problem Phenomenon
【Problem Phenomenon】The LCP molding cycle is not fully utilized; cooling time set too long wastes capacity
Cause Analysis
LCP crystallizes extremely fast and solidifies quickly after filling; the required cooling time is far shorter than conventional engineering plastics; Fictiv points out that rapid crystallization can significantly shorten the LCP cycle
Solution
Gradually shorten the cooling time and verify demolding quality; use the rapid crystallization characteristic to speed up mass production; coordinate mold temperature and ejection optimization to compress the cycle to a reasonable lower limit; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP's fast crystallization is a capacity dividend; cooling time should be stepped down and verified level by level; 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
