PVC Injection Product Dull Surface
문제 현상
Products dull and not bright, poor appearance.
원인 분석
Low mold temperature, poor plasticization, degradation darkening; PVC gloss is dually affected by plasticization and degradation; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based solely on experience.
해결 방법
①Appropriately increase mold temperature to improve melt replication and fit to cavity surface; ②Improve plasticization quality, eliminate unplasticized particles; ③Prevent degradation; ④Polish cavity; ⑤Stabilize melt temperature curve, avoid quality drift caused by temperature fluctuation.
핵심 요약
PVC gloss = 'plasticization + mold temperature + anti-degradation': degradation dragging gloss dark is PVC's characteristic; plasticization and mold temperature manage replication, anti-degradation manages base color; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
