To answer all your questions, I am not expecting perfectly parallel in all scenarios. It will be compressing fibre mats. The mats will be roughly flat already before compressing, roughly uniform at all locations, and be aligned in the centre of the test rig. So there won't be huge eccentric...

I didn't know about die sets before. It seems they're used to stamp items? Would they be robust and maintain parallel?

I'm creating a test rig whereby a component needs to be compressed between the plates at around 8 atm of pressure, while being forced flat if it...
We already own the press and there's only 1 hole in the ram; I don't think I'd be allowed to go and drill another one, and I can't guarantee they would be perfectly vertical.
I guess one thing I didn't mention is that this fixture needs to be removable 100% from the press as it's used for a lot...
So I'm designing a test rig in a hydraulic press. This is the general overview, the green is a section cut view.
The bottom plate is firmly attached to mounting holes on the press. The top plate will be pushed downwards by the press, compressing a not-necessarily flat object between it and...

I was reading this thread and the final result was inconclusive. My stairway is going to be open on both sides and less than 44" wide.
