Looks like a nice specialty program for those that design stamped parts. Tooling is a critical part of any design. this deals with that. I am retired aero space engineer that packaged electronics down to the semiconductor level. I did design a shallow drawn package for 5 compression bonded semiconductors that were hermetically seal. Had holes for feed throughs. The lid was designed to deflect to apply the load of 5 tons, one ton for each semiconductor. The was a 1000 amp switch. The feed throughs and the lid were cold welded to the bottom stamping. An aluminum bottom and lid and copper flange sheet metal for the feed throughs.
