Pre-drying:

Dryer type: dry air dryer.
Temperature: 120 – 130°C
Drying time: 2 – 3 h
Target moisture content: <0.02%.

Recommended basic settings:

Melt temperature: 300 – 325°C
Mold temperature: 140 – 160°C
Injection speed: medium – high
Holding pressure: high
Back pressure: 40 – 80bar (spec.)

Machine selection:

Screw: special injection units for magnetic compounds; low compression screws with non-return valve
Nozzle: Open nozzle
Wear protection: Wear and corrosion protected according to machine manufacturer’s recommendation suitable for processing magnetic compounds
Injection unit: Shot volume = 50-80% of maximum metering volume

Further important processing information:

The residence time of the melt in the screw antechamber should be kept as short as possible. If this is not observed, segregation can occur due to the large difference in density between the filler and the substrate if the downtimes are too high. The ideal here is metering time = cooling time. A medium back pressure leads to optimum homogenization. Due to the high filler content, the spraying equipment must be equipped with wear and corrosion protection.
