with optimum strength and toughness. Nylon 66 materials are
hygroscopic and will become degraded by excessive moisture during the
injection molding process. For unopened bag/box, dry at 140F (60C) for
1-2 hours. For material exposed to the atmosphere, if additional
drying is needed, dry at 150F (66C) or until the moisture level is
between 0.04 - 0.20%.
PROCESSING
Melt Temperature: 288 – 305C (550 – 580F)
Mold Temperature: 60 – 100C (140 – 212F)
Injection Pressure: 35 – 125 MPa (5000 – 18000 psi)
Back Pressure: 0 – 0.35 MPa (0 – 50 psi)
Screw RPM 40 – 80
Screw Compression Ratio:3:1 – 4:1
This product can be processed over a wide range of mold
temperatures; however, for applications where aesthetics are
critical, a mold surface temperature of 60-100C (140-212F)
is recommended.
Injection pressure controls the filling of the part and should
be applied for 90% of ram travel. Packing pressure affects
the final part and can be used effectively in controlling
sink marks and shrinkage. It should be applied and maintained
until the gate area is completely frozen off.
Fast fill rates are recommended to insure uniform melt
delivery to the cavity and prevent premature freezing.
