Fenómeno do problema
Bubbles inside parts.
Análise das causas
Material contains moisture, poor venting, or insufficient shrinkage compensation of thick walls; degradation gas generation also forms them.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solução
①Strengthen drying; ②optimize venting; ③strengthen holding pressure shrinkage compensation; ④control temperature to prevent degradation.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Bubbles are identified in four categories: moisture, trapped air, vacuum bubble, and degradation.; 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
