TPE Delamination (Moisture Type)
Problem Phenomenon
Batches with insufficient drying show delamination coexisting with silver streaks.
Cause Analysis
After the material absorbs moisture, water vaporizes during '2079851475616104452, separating melt layers; hygroscopic TPE or damp batches have high incidence.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Dry according to the supplier data sheet; ②control drying temperature, time and dew point; ③sealed storage; ④re-dry damp batches.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Moisture-type delamination and silver streaks share the same source; drying verification is the first troubleshooting action.; after confirming effectiveness, fix 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
