ASA Ejector Whitening and Cracking
Sorun Belirtisi
【Problem Phenomenon】Whitening or ejector penetration at ejector pins of ASA products, demolding damage
Neden Analizi
Insufficient cooling low product strength, too few and too small ejector pins, too fast ejection speed cause local stress to exceed limit; although ASA toughness is good, concentrated ejection force still causes damage; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Çözüm
Extend cooling to increase demolding strength; increase ejector pins to balance ejection; reduce ejection speed; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
ASA ejector whitening check cooling and ejection balance, do not hard-eject soft parts; 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
