Pre-drying:

Dryer type: dry air dryer (!).
Temperature: 120 – 140 °C
drying time: 4 – 8 h
Recommended max. residual moisture: < 0.02 %.

Recommended basic settings:

melt temperature: 320 – 340°C
Mold temperature: 140 – 180°C (As a rule of thumb, the higher the requirements, the higher the mold temperature).
Back pressure: < 10 bar (spec.)

The injection speed should be set as a slow – fast – slow profile. As a principle: as fast as possible, as slow as necessary.

Machine selection:

In the processing of KEBATRON PPS, wear- and corrosion-protected injection units have proven their worth. The injection unit should be selected so that the shot volume is 50 – 80% of the maximum metering volume. The dwell time should be kept as short as possible.
