EMA '2079851475616104452 Insufficient Flow Length Ratio
Sorun Belirtisi
EMA '2079851475616104452 flow length ratio only 80-100, below 150, thin-wall products cannot be filled
Neden Analizi
EMA melt viscosity high, flow distance short; injection temperature low; injection pressure insufficient; mold runner resistance large
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 EMA high viscosity; high temperature, high pressure and large gates are key
