Dryer type: dry air dryer
Temperature: 80°C
Drying time: 4-8 h
Moisture content during processing: < 0.02%.

Recommended basic settings:

Melt temperature: 250 – 260°C
Mold temperature: 90 – 120 °C
Injection speed: high
Back pressure: 40 – 80bar (spec.)

Machine selection:

Screw: Low compression screw with non-return valve
Nozzle: Open nozzle
Wear protection: Wear and corrosion protected according to machine manufacturer’s recommendation, suitable for processing highly filled plastics
Injection unit: Shot volume = 50-80% of maximum metering volume

Other important processing notes:

The residence time of the melt in the barrel 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 polymer if the dwell time is too high. The optimum is: metering time = cooling time. A medium back pressure leads to optimum homogenization. Due to the high filler content, the injection moldinge quipment, including mold cavities, must be equipped with suitable protection against abrasive wear. When designing parts and molds for processing KEBABLEND / H 27.1200 PBT, high shear rates must be avioded to prevent excessive wear. This includes suitable dimensions of cold/hot runner systems and gating. Areas of the mold in which high shear rates cannot be avoided should be designed as exchangeable mold inserts. We recommend to consider shortened maintenance intervals and increased wear in your calculations.
