TPU product air traps
ظاهرة المشكلة
Gas marks and burnt appear at the end of the melt flow.
تحليل الأسباب
Poor venting compresses gas; high-speed filling aggravates air traps; 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
الحل
①open vent grooves at the end; ②reduce injection speed; ③clean the vent grooves; ④optimize the gate position; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
The air trap position is where vents should be added; special attention must be paid to venting for high-speed filling of elastomers; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
