PC Product Surface Orange Peel
문제 현상
The PC product surface shows orange-peel-like fine unevenness, and the high-gloss requirement is not met.
원인 분석
Insufficient pressure at the filling end and fast front cooling cause poor surface replication; low mold temperature or insufficient holding pressure; poor surface replication is the essence; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience.
해결 방법
①Increase mold temperature and holding pressure; ②Increase end filling pressure; ③Open or clean vent slots at the corresponding positions to ensure smooth gas discharge; ④High-polish the cavity; ⑤Optimize the injection speed curve to keep the melt front advancing steadily.
핵심 요약
PC orange peel = 'poor replication': supplement both pressure and temperature; end replication of high-gloss parts is the difficulty, mold temperature and holding pressure must be given sufficiently; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence.
