PC/ABS delamination (melt temperature too low)
문제 현상
Layered peeling on part surface.
원인 분석
Too low melt temperature causes poor fusion between melt layers; material contamination can also cause delamination.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
해결 방법
①Raise barrel temperature to within the window; ②check material purity; ③clean the barrel to eliminate contamination; ④verify whether delamination is eliminated.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
For PC/ABS delamination, first raise the temperature to verify; if raising temperature is ineffective, then check material contamination.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
