Process Techniques
Extruding techniques
The recommended setting temperatures for each zone of the extruder are as follows:
| Screw | Neck | Flange | Die |
|---|---|---|---|
|
160℃-190℃ |
190℃ |
190℃ |
195℃-210℃ |
The above temperature is reference temperature, due to equipment differences, screw compression ratio difference, customer should choose suitable temperature according to their own equipment condition.
