LCP Product Brittleness Problem
Problem Phenomenon
Product breaks brittlely under impact.
Cause Analysis
LCP itself has a certain brittleness; weld lines are even weaker points; excessive shear also reduces toughness.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
Solution
①Avoid weld lines in stressed areas; ②select toughened or filled grades; ③control shear heat; ④round structural corners.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP brittleness management relies on grade and design; weld line avoidance is the focus.; 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
