For harder to fill parts the temperatures may have to be increased. Keep lower temperatures in the rear zones to
allow venting throughhopper.
Melt Temperature
Maximum temperature with a hand pyrometer should be 370° F to 420° F.
Mold Temperature
Minimum “A” surface steeltemperature 120º F to 140º F (49º C to 60º C).
Injection Pressure
The preferred range is 50 to 60% of machine capacity. Pressure should be sufficient tofill the mold without
hesitation or flashing.
Holding Pressure
Setting should be lower than boost pressure with a minimum amount of time to preventover-packing of the part.
Injection speed
Slow to medium speed to prevent excessive shear on the material.
Cushion
Maintain at 10-20 mm toprovide enough material for consistent parts.
Decompression
Use only when necessary to prevent nozzle drool.
Screw RPM
Screw should stop 1 to 2seconds before mold open. A lower RPM is preferred for mixing and uniform melt
temperature.
Drying
Material should be dried for a minimum of 2 hours anda maximum of 4 hours at 212º F (100º C).
