32 more companies were named at least once. Companies outside the top ten are counted in the averages but not named here.

Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Illinois. 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. 1“Best castings suppliers in Illinois”
  2. 2“Who supplies precision machined aluminum die cast housings in Illinois”
  3. 3“I need a Illinois casting partner for a 10,000-piece hydraulic valve body run, who should I talk to”
  4. 4“Top castings suppliers in Illinois for industrial OEM buyers”
  5. 5“Which Illinois casting suppliers can handle complex thin-wall investment castings with secondary machining”
  6. 6“List 20 castings companies in Illinois 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.
