ASA Deformation Recurrence After Annealing
Sorun Belirtisi
【Problem Phenomenon】ASA products are stable short-term after annealing, deformation reappears after storage
Neden Analizi
Insufficient annealing temperature or time only releases part of the stress; amorphous materials have narrow annealing window, too high temperature self-softens and deforms; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Çözüm
Annealing set at 10-15℃ below heat deflection and held for sufficient time; slow cooling after annealing; verify storage stability; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
ASA annealing temperature is delicate work, both insufficient and excessive fail; after confirming effectiveness, fix 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
