PCABS Uneven Gloss
Fenómeno do problema
[Problem Phenomenon] PC/ABS high-gloss parts have regional gloss differences, and the appearance is unqualified
Análise das causas
Uneven mold temperature and cavity surface differences lead to different replication; PC/ABS high-gloss parts have high requirements for mold temperature stability; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
Uniform and stable mold temperature of 60-80°C; consistent cavity polishing; optimize venting to prevent local gas trapping; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusão principal
For poor PC/ABS gloss, check mold temperature stability, assisted by consistent polishing; 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 problems in the future
