TPE flow marks
Sorun Belirtisi
Flow marks and uneven gloss on the surface of TPE products
Neden Analizi
The melt front state is unstable; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Çözüm
Increase melt temperature and mold temperature; speed optimization; gate position improvement; 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, so as to locate effective measures
Temel Çıkarım
Flow marks are improved by temperature and speed; 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 similar problems later
