TPE Flash
ظاهرة المشكلة
Flash appears at the parting line.
تحليل الأسباب
Insufficient clamping force or excessive injection pressure; TPE low hardness grades have low melt viscosity and penetrate gaps more easily.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
الحل
①Check the clamping force; ②reduce injection pressure; ③repair the parting line; ④optimize the holding pressure curve.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
Soft TPE has high requirements for clamping and parting line precision; pressure control is the key.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
