Magnetic properties
Pre-drying may be necessary to achieve perfect processability in the injection molding process:
Recommendation:
Dryer type: dry air dryer
Temperature: 80 °C
Drying time: 3-6 h
Recommended basic settings:
Melt temperature: 260 – 280 °C
Mold temperature: 60 – 80 °C
Injection speed: medium – 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 the 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 carrier material 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 injection unit must be equipped with wear and corrosion protection.
