PPO Surface Roughness and Gloss Loss
문제 현상
[Problem Phenomenon] PPO product surface is rough with poor gloss, and cavity replication is poor
원인 분석
Low mold temperature and insufficient melt temperature prevent the melt from fully replicating the cavity surface; the hot mold process can simultaneously reduce roughness; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Raise mold temperature and melt temperature to improve surface replication; check cavity surface condition and venting; take the upper limit of the mold temperature window for appearance parts; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
PPO surface replication relies on both temperatures, and hot mold is a direct means of reducing roughness; 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
