Fenómeno do problema
Sink marks and flash coexist.
Análise das causas
Improper holding pressure setting; imbalance between shrinkage compensation and overpacking.; during on-site troubleshooting, verify item by item according to this mechanism, 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
①Optimize holding pressure and time; ②staged holding pressure; ③set according to solidification time; ④verify balance.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
The holding pressure profile must balance shrinkage compensation and overpacking.; 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 later
