TPU product processing temperature window
Fenómeno del problema
Quality varies greatly between machines.
Análisis de la causa
The TPU temperature window is narrow, and machine temperature control differences are directly amplified; the lack of a unified actual melt temperature is the root cause; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
①unify the actual melt temperature benchmark; ②calibrate thermocouples; ③establish process cards; ④test by batch; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Narrow-window materials have high requirements for equipment consistency; unifying the actual measurement benchmark is the key; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
