LCP Product Stress Testing
Problem Phenomenon
Internal stress evaluation.
Cause Analysis
LCP internal stress is related to orientation; conventional testing methods need adaptation.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Test stress by direction; ②thermal aging evaluation; ③slice analysis of orientation; ④correlate with performance.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP stress evaluation must consider directionality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
