Análise das causas
Uneven mold temperature and cavity surface differences; PC gloss is sensitive to mold temperature and stress; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
Uniform mold temperature at the upper limit; consistent cavity polishing; venting optimization; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Conclusão principal
For PC gloss difference, check mold temperature uniformity; stress also affects it; 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
