Manufacturing Villages come in two flavors: wholesale and retail.
Retail is the easiest to describe: customized products sold directly to the customer, mostly via the web.
Wholesale manufacturing villages make small products in mass amounts sold bu someone else or included in a larger assembly. Some examples are light bulb sockets and switches. Extension cords and bungy cords, too. Wholesale products now made overseas should be produced here wwith modern automation and design/production software.
The basic structure of central services surrounded by satellite manufacturers stays the same. So take your pick: individual customized products, commonly called job-shop production, or set up to crank out thousands and thousands of wholesale products you improve in incremental ways.
