TPU narrow processing window
Fenómeno do problema
Slight fluctuations in TPU process parameters cause defects, and the window is obviously narrower than other elastomers
Análise das causas
The processing temperature fluctuation range of TPU is particularly narrow, requiring the '2079851475616104452 machine to have precise temperature adjustment and control systems; any fluctuation of the three elements of temperature, pressure, and time will manifest as product defects
Solução
①'2079851475616104452 machine temperature control accuracy ±3℃; ②strict monitoring after process parameters are locked; ③evaluate upgrading old equipment with large fluctuations; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
The narrow window of TPU is its process difficulty; equipment precision and parameter discipline are the prerequisites for stable production; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
