TPE Product Melt Fracture
Sorun Belirtisi
Sharkskin-like texture on the surface.
Neden Analizi
Die shear too high; low temperature and small gap aggravate it.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Çözüm
①Raise the die temperature; ②widen the gap; ③reduce speed; ④processing additive.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
Melt fracture is shear instability; temperature and gap adjustment alleviates it.; 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
