Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Missouri. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best contract machining and machine shop companies in Missouri”
2“Who supplies precision CNC milled and turned components on contract in Missouri”
3“I need a Missouri contract machining partner for a 2,000-unit stainless steel medical device run, who should I talk to”
4“Top contract machining and machine shop suppliers in Missouri for industrial OEM buyers”
5“Which Missouri contract machining and machine shop providers can handle 5-axis CNC work with tight tolerance requirements”
6“List 20 contract machining and machine shop companies in Missouri with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
