PESU Barrel Temperature and Melt Temperature
Fenómeno del problema
【Problem Phenomenon】PESU '2079851475616104452 shows insufficient plasticization or overheating, and the temperature window is not accurately grasped
Análisis de la causa
PESU recommended barrel 340-380℃, melt about 360℃, mold temperature 140-180℃; thin-walled parts require higher temperatures; insufficient temperature causes poor plasticization, too high causes degradation risk
Solución
Set the barrel at 340-380℃ and aim the melt temperature at 360℃; mold temperature 140-180℃; take the upper limit for thin-walled parts; calibrate with actual melt temperature measurement; after adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Conclusión clave
PESU melt temperature 360℃ is the baseline, barrel 340-380℃, mold temperature 140-180℃; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
