OP
We did titanium extrusion in Albany Oregon. I don't know the names of the companies now because they keep changing names.
The aluminum extrusion was done for Vari-wall. They mostly made baseball bats but there were a few much more critical projects.
If you guys think you can install python or anaconda I would write a auto tuning for temperature pretty quick. It would need to have the data stored in a .csv file in 3 columns of time, control and PV.
At this time I have a Scilab autotuner here

Someone used it and like enough to add a simple GUI

Here is data from the heat exchanger example on the controlguru site.

Here is a picture of the results

However, I decided that Scilab was too much of a kludge and decided to switch to python.
