LCP Product Venting Design
Problem Phenomenon
Trapped gas problems.
Cause Analysis
LCP fills extremely fast and the venting window is short; venting must be designed in advance.; 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
①Sufficient venting design; ②focus on ends and confluence areas; ③vent depth adapted to low viscosity; ④regular cleaning.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP vent depth must be shallower to prevent flash; dual constraints of low viscosity and high-speed filling.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
