| Processing Guide: | PA 6 - Polyamide 6 |
|
|
| Extruder: |
Single Screw Extruder Without vacuum, plain feeding section or pressure-relieved grooved feeding section (by increased screw pitch and channel depth) |
|
|
| Screw Design: |
Barrier Screw or Polyolefin Screw with equal feed ,transition and metering section, 25-30 L/D Two mixing sections: dispersive-mixing spiral-shear element, rhomboid distributive-mixing section |
|
|
| Compression Ratio: | 3-4:1 |
|
|
| Cylinder Temperatures: |
230-260 C 446-500 F |
|
|
| Melt Temperature: |
230-290 C 446-554 F |
|
|
| Pre-Drying: | 3 hours at 80 oC (176 F) (very important) |
|
|
| Calibration: | |
|
|
| Miscellaneous: |
process above 220 oC ( 428 F) to avoid freeze-off if bubbles come then temperature too high increased output/reduced wear by preheating of material 75 C (167 F) or by heating of feeding section at 150 C (302 F) |
