LDPE '2079851475616104452 Flash
Fenómeno del problema
Flash on product edges; the low viscosity of LDPE causes flash even in tiny gaps
Análisis de la causa
LDPE melt has low viscosity and good fluidity, and is sensitive to parting line fitting accuracy; injection pressure too high or insufficient clamping causes flash; mold wear enlarges the gap; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
① Ensure parting line fitting accuracy; ② injection pressure just sufficient is enough; ③ regular mold maintenance to prevent wear; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
LDPE flash is the price of low viscosity; mold accuracy and pressure control are the two major defense lines; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
