TPU vs TPE Comparison
Problembeschreibung
Cost increased after replacing TPE products with TPU
Ursachenanalyse
TPU has high performance but high price, and its performance is excessive for ordinary applications; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Lösung
Select material according to performance requirements: TPU for high wear resistance and high resilience, TPE for general elasticity; 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
Wichtigste Erkenntnis
TPU and TPE are selected in a graded manner according to performance requirements; after confirming effectiveness, solidify 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 in the future
