Effect of POM mold temperature on rigidity
Fenómeno do problema
POM product rigidity fluctuates between batches
Análise das causas
Mold temperature affects crystallinity and thus rigidity, and mold temperature fluctuations are directly transmitted to mechanical properties; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
Lock the mold temperature within ±2°C; take the upper limit of mold temperature for rigidity-required parts; include crystallinity in quality monitoring; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Mechanical property stability begins with mold temperature stability; after confirming effectiveness, fix 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
