PBAT '2079851475616104452 flash
Fenómeno del problema
Flash at the parting line of PBAT '2079851475616104452, due to insufficient clamping force or excessive injection pressure.
Análisis de la causa
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
Solución
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
Conclusión clave
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
