DSTDP injection insufficient flow length ratio
Sorun Belirtisi
DSTDP injection flow length ratio only 80-100, below 150, thin-wall products cannot be filled
Neden Analizi
DSTDP melt viscosity high, flow distance short; injection temperature on the low side; injection pressure insufficient; mold runner resistance large
Çözüm
1) Raise injection temperature to 160-200°C; 2) raise injection pressure 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 DSTDP high viscosity; high temperature, high pressure and large gate are key
