PESU Barrel Temperature and Melt Temperature
Problem Phenomenon
【Problem Phenomenon】PESU '2079851475616104452 shows insufficient plasticization or overheating, and the temperature window is not accurately grasped
Cause Analysis
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
Solution
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
Key Takeaway
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
