TPU product dimension instability
Fenómeno del problema
Large dimensional deviation between batches.
Análisis de la causa
The elastic recovery of TPU makes the dimensions change over time after demolding; process fluctuations and batch differences amplify dimensional fluctuations; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
①stabilize '2079851475616104453 parameters; ②measure the product after aging; ③control material batches; ④establish dimensional SPC; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
TPU dimension judgment must allow sufficient aging time; dimensional management of elastic materials relies more on process stability; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
