PPO High Mold Temperature Improves Overall Quality

Fenómeno do problema
【Problem Phenomenon】PPO products have poor flow, weak weld lines and rough surface coexisting
Análise das causas
The recybase guide points out that non-reinforced NORYL running at 66-93℃ mold temperature can improve flow, weld line strength and surface finish; mold temperature is a common adjustment means for multiple PPO defects
Solução
When defects occur frequently, prioritize evaluating raising mold temperature; distribute mold temperature evenly to eliminate local differences; coordinate with melt temperature adjustment; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusão principal
PPO raising mold temperature kills three birds with one stone: flow, weld lines and surface improve simultaneously; 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 subsequent similar problems
