PP Uniform Wall Thickness Design
문제 현상
[Problem Phenomenon] Sudden PP wall thickness changes cause batch defects of sink marks and warpage
원인 분석
PP's high shrinkage makes sink marks and warpage more obvious at sudden wall thickness changes; uniform wall thickness plus gradual transition is the fundamental prevention; reduce material in thick areas; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
해결 방법
Uniform wall thickness to avoid sudden changes; reduce material and add ribs in thick areas; rib thickness 50-60% of the main wall; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Uniform PP wall thickness is fundamental for preventing sink marks and warpage; 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 similar future problems
