TPU Hardness Selection
Fenómeno do problema
TPU product feel does not match the design
Análise das causas
TPU hardness range is wide (Shore A60-D80), and grade selection directly determines the feel; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solução
Select hardness according to application: soft touch A60-85, structural support above A85; prototype verification; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
TPU hardness selection is verified by prototyping first; 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
