LCP Product Hot Runner
Problem Phenomenon
Hot runner application problems.
Cause Analysis
LCP's low viscosity places high demands on hot runner sealing; valve pin leakage causes drooling.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
Solution
①Select hot runners suitable for low-viscosity materials; ②reliable valve pin sealing; ③precise temperature control; ④regular maintenance.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP hot runners must adapt to the low-viscosity characteristic; sealing is the selection 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
