This is a made in Mexico Wix/Affinia filter, made for NAPA on 09/24/2015. I don't have a vehicle that this filter fits on so it sat unused for years. Recently I looked at my stash of filters and saw this one pretty well rusted and I decided to put it on the chopping block. Don't know why this one rusted sitting in a box next to a bunch of other filters (mostly Fram and PrimeGuard) and none of those were rusted.

When I cut it open I saw at least 4 spots where the media was not glued to the end cap. It looks like they did not use enough glue when they glued it together.

I really don't think that any filters nowadays are assembled by hand, but I don't know for sure.
Other parts of the world some are ... ie, filter making in the middle east videos showing the process.
