ABS wall thickness uniform design
문제 현상
[Problem phenomenon] ABS wall thickness abrupt changes cause batch defects of sink marks and warpage
원인 분석
Wall thickness should be maintained at 1.5-3.5mm with uniform transition; abrupt changes cause large cooling shrinkage differences producing sink marks and internal stress; structural design is the fundamental prevention; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
해결 방법
Wall thickness controlled at 1.5-3.5mm uniformity; gradual transition at abrupt changes; reduce material and add ribs in thick areas; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
ABS wall thickness 1.5-3.5mm uniform, abrupt change is the root of all evil; 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
