Stampaggio ad Iniezione
To avoid hydrolytic degradation during processing, RITEFLEX resins have to be dried to a moisture level equal to or less than 0.05%. Drying should be done in a dehumidifying hopper dryer capable of dewpoints <-30°F (-34°C) at 225°F (121°C) for 4 hours.
Rear Temperature 370-390(185-200) deg F (deg C)
Center Temperature 390-410(200-210) deg F (deg C)
Front Temperature 390-420(200-215) deg F (deg C)
Nozzle Temperature 390-420(200-215) deg F (deg C)
Melt Temperature 390-420(200-215) deg F (deg C)
Mold Temperature 75-125(20-55) deg F (deg C)
Back Pressure 0-50 psi
Screw Speed Medium
Injection Speed Fast

Injection speed, injection pressure and holding pressure have to be optimized to the individual article geometry. To avoid material degradation during processing low back pressure and minimum screw speed have to be used. Overheating of the material has to be avoided, in particular for flame retardant grades. Up to 25% clean and dry regrind may be used.
