ASA Weld Line Dark Color
문제 현상
ASA dark-colored products have obvious weld lines, increase melt temperature and speed.
원인 분석
ASA weld lines are very obvious on dark colors; increase melt temperature and injection speed; convergence temperature; venting; gate design; appearance management.; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
해결 방법
①Melt temperature increased; ②injection speed increased; ③convergence area venting; ④gate optimization; ⑤appearance standard.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
Temperature and speed are the main countermeasures for ASA dark weld lines; gate design shifts position; standards manage acceptance.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
