PBAT '2079851475616104452 flash
Fenómeno do problema
Flash at the parting line of PBAT '2079851475616104452, due to insufficient clamping force or excessive injection pressure.
Análise das causas
PBAT injection pressure demand; insufficient clamping force; mold wear gap; poor parting line fit; injection speed too fast.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
①Verify clamping force is sufficient; ②fit the mold parting line; ③optimize injection pressure and speed; ④check mold wear.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Clamping and mold are the hardware factors of PBAT flash; process optimization is the software adjustment; regular inspection prevents gradual change.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
