PLA product weld lines
문제 현상
Weld lines are obvious and strength is low.
원인 분석
Low flow front temperature causes poor fusion; PLA's fast solidification aggravates it.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
① Increase temperature; ② optimize the gate; ③ increase convergence speed; ④ set overflow wells.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
핵심 요약
Weld lines rely on temperature and gate management.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
