TPU Hardness Deviation
ظاهرة المشكلة
The hardness of TPU products deviates from the design value
تحليل الأسباب
Raw material batches, drying state, and process temperature all affect hardness; when troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
الحل
Incoming material hardness inspection; process locking; first article hardness testing; 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
الخلاصة الأساسية
Hardness consistency relies on full-chain control; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems later
