It sounds like they're calling them "weapon foundries." (Destiny)

I was browsing through the Art of Destiny last night and came across the pages with a bunch of logos on them including:

I forget if it was Luke or DeeJ but one of them mentioned expanding the manufactures and making them more important. We've seen the Suros rocket launcher and a new rifle of some kind. Perhaps Omolon and others will have expanded product lines as well!

They talked about these a lot during the (very informative) gameplay video that unoudid linked yesterday.
