PPO Design Wall Thickness Uniformity
문제 현상
[Problem Phenomenon] Uneven wall thickness in PPO product design causes batch problems of sink marks and warpage
원인 분석
Although PPO shrinkage is small, sudden wall thickness changes still cause sink marks and internal stress; uniform wall thickness design is the premise of quality, in conjunction with its 0.8mm lower limit; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Uniform wall thickness design to avoid sudden changes; reduce material and add ribs in thick areas; wall thickness ≥0.8mm and check the gate according to flow length; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Uniform wall thickness in PPO design is an iron rule, and the 0.8mm lower limit must be held; after confirming effectiveness, solidify 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
