TPU Insufficient Filling
Fenómeno del problema
TPU thin-wall products short shot
Análisis de la causa
TPU melt viscosity is high, and thin-wall filling resistance is large; 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
Solución
Take the upper limit of melt temperature; increase injection speed; enlarge the gate; 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
Conclusión clave
TPU short shot relies on temperature, speed and gate; 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
