I see that the OP has not returned. I hope he hasn't been scared away.
I would be curious to know what do they do that he thinks is design?
Perhaps what they are doing is actually planning for production and not design. I remember a few years ago working with a foundry who made castings to customer design, but to ensure that the castings properly filled they designed the gates and risers needed to ensure that when the molten metal was poured into the mold, it was distributed evenly and completely with no voids.
The activity of designing gates and risers is not design, as it is only what they need to do to ensure that the product comes out meeting print specifications.
Creating a CNC program to ensure that machined parts meet print requirements is another example of an activity that is performed to ensure the parts are made correctly but is not design.
Design of tooling to make parts is another example of planning of production, not parts design.
So, OP, if you are still around, we can help you more if you explain what the actual activity is that you are concerned about.
