ASA regrind drying and ratio
Sorun Belirtisi
[Problem phenomenon] ASA blended with regrind has appearance and hue fluctuations, drying follows new material parameters
Neden Analizi
Regrind particle size after crushing increases surface area and absorbs moisture faster, drying time needs extension; regrind thermal history affects hue, when ratio is out of control appearance fluctuates between batches; during on-site investigation, verify item by item according to this mechanism, avoid blindly adjusting the machine based on experience alone
Çözüm
Regrind dried separately with extended time; ratio controlled within 20-30%; appearance sensitive parts limited or prohibited from using regrind; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
ASA regrind drying needs extra, ratio and hue dual control; 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 subsequent similar problems
