2 is op, 3 is fpm, 4 is the wall thickness and 5 is OD.
What is 6?
Is that all at constant pressure?
It is late now, will have a look tomorrow.
oops, 6 is the length of the tube in ft. We set the extruder at a fixed rpm, the pressure jumps around a bit more than we like, but it has no controls to keep the pressure constant.
I misunderstood what you meant by pressure earlier, I see now (I think) that you mean the plastic pressure in the extruder. So when you talked about adjusting the pressure to adjust the wall thickness did you mean that you adjust the extruder rpm? If so I will have to think again about what is the relationship between extruder rpm, puller speed, and the internal and external diameters.
[Edit] Also what rpm was the extruder running at in the csv you posted?
We set the extruder at a set RPM and don't vary it at all, the machine has no automated control for the pressure of the material going into the extruder head.
I am confused then, I thought you said that you adjusted the pressure to get the right wall thickness.
Kindly keep it here this is good info
