Which process to use?

I have a new project coming up. Large medical device, 60 inches wide, 30 inches deep and 72 inches tall, needs skins. Total production will be about 500. Considering the size of the panels and quanity, I think thermo/pressure forming and bent metal are two possiblities. Structural foam may be another option, but I don’t know if 500 is enough for that process. Any thoughts about the structural foam or any other processes?
