Insufficient EEA injection flow length ratio
Sorun Belirtisi
EEA injection flow length ratio only 80-100 below 150, thin-wall products cannot be filled
Neden Analizi
EEA melt viscosity high, short flow distance; injection temperature too low; insufficient injection pressure; large mold runner resistance
Çözüm
1) Increase injection temperature to 160-210°C; 2) Increase injection pressure to 80-100MPa; 3) Enlarge 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 EEA high viscosity; high temperature, high pressure and large gate are the key
