Stampaggio ad Iniezione
To avoid hydrolytic degradation during processing, IMPET resins have to be dried to a moisture level equal to or less than 0.01%. Drying should be done in a dehumidifying hopper dryer capable of dewpoints <-30°F (-34°C) at 275°F (121°C) for 4 hours.
Rear Temperature 500-520(260-270) deg F (deg C)
Center Temperature 520-530(270-275) deg F (deg C)
Front Temperature 530-540(275-280) deg F (deg C)
Nozzle Temperature 530-550(275-290) deg F (deg C)
Melt Temperature 520-570(270-300) deg F (deg C)
Mold Temperature 230-250(110-120) deg F (deg C)
Back Pressure 0-25 psi
Screw Speed 50-75 rpm
Injection Speed Medium/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.
