CEF injection flow length ratio insufficient
Sorun Belirtisi
The CEF injection flow length ratio is only 80-100, lower than 150, and thin-walled products cannot be filled
Neden Analizi
The CEF melt viscosity is high and the flow distance is short; the injection temperature is low; the injection pressure is insufficient; the mold runner resistance is large
Çözüm
1) Increase the injection temperature to 160-220°C; 2) Increase the injection pressure to 80-100MPa; 3) Enlarge the runner and gate sizes to reduce resistance; 4) Add 0.3-0.5wt% flow aid to reduce viscosity
Temel Çıkarım
Insufficient flow length ratio is caused by the high viscosity of CEF; high temperature, high pressure and large gate are the key
