PSU Mold Temperature and Molding Window
Problembeschreibung
[Problem Phenomenon] PSU mold temperature set too low makes products brittle with high stress; set too high lengthens the cycle
Ursachenanalyse
PSU mold temperature is recommended at 120-160°C (the handbook gives a wide range of 93-179°C); hot molds reduce internal stress and improve flow; insufficient mold temperature makes stress and brittleness problems prominent
Lösung
Set mold temperature at 120-160°C with uniform distribution; take the upper limit for thick-wall parts and extend cooling; use oil temperature units to ensure high-temperature stability; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
PSU mold temperature 120-160°C is the balance point between stress and flow; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
