ASA melt temperature window
Sorun Belirtisi
[Problem phenomenon] ASA melt temperature too low causes insufficient filling, too high causes degradation discoloration, window grasping inaccurate
Neden Analizi
ASA melt temperature window 230-280°C: Plasthub recommends 230-260°C to preserve performance, Fast Heat upper limit 280°C for thin-wall long flow paths; exceeding the upper limit causes styrene monomer precipitation and degradation
Çözüm
Conventional molds set at 230-260°C; thin-wall long flow paths can explore 280°C but shorten residence; discoloration or bubbles immediately reduce back to safe zone; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
ASA melt temperature 230-260°C normal state, 280°C is the thin-wall emergency upper limit; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
