ASA Insufficient Heat Deformation Resistance
Sorun Belirtisi
【Problem Phenomenon】ASA products deform in high-temperature environment, heat deflection temperature overestimated
Neden Analizi
ASA heat deflection is about 88-101℃ (load related), actual use temperature should leave margin; glass fiber reinforcement can improve but limited; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Çözüm
Design use temperature by HDT minus margin; high-temperature scenarios choose glass fiber or high heat resistance grades; over-temperature occasions evaluate PC/ASA; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
ASA heat deflection 88-101℃, leave margin for use temperature; 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
