Insufficient flow length ratio in EAA '2079851475616104452
문제 현상
The flow length ratio of EAA '2079851475616104452 is only 80-100, below 150, thin-walled products cannot be filled
원인 분석
EAA melt viscosity is high, flow distance is short; injection temperature too low; insufficient injection pressure; large mold runner resistance
해결 방법
1) Raise the injection temperature to 180-240°C; 2) Increase the injection pressure to 80-100MPa; 3) Enlarge the runner and gate size to reduce resistance; 4) Add 0.3-0.5wt% flow aid to reduce viscosity
핵심 요약
Insufficient flow length ratio is caused by the high viscosity of EAA; high temperature, high pressure and large gate are the key
