| Processing Guide: | PA 66 - Polyamide 66 |
 |
|
| Extruder: | Single Screw Extruder Without vacuum, plain feeding section |
|
|
| Screw Design: | Barrier Screw or Polyolefin Screw with equal feed ,transition and metering section, 25-30 L/DTwo mixing sections: dispersive-mixing spiral-shear element, rhomboid distributive-mixing section |
|
|
| Compression Ratio: | 3-4:1 |
|
|
| Cylinder Temperatures: | 260-290 C 500-554 F |
|
|
| Melt Temperature: | 280-300 C 536-572 F |
|
|
| Pre-Drying: | 3 hours at 80 C (176 F) (very important) |
|
|
| Calibration: | |
|
|
| Miscellaneous: | process above 250 oC (482 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 160 C (320 F) |
