9 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 Michigan. 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 suppliers of industrial springs in Michigan”
  2. 2“Who supplies custom high-cycle compression springs in Michigan”
  3. 3“I need a Michigan spring manufacturer for a 100,000-piece industrial valve spring run, who should I talk to”
  4. 4“Top industrial spring suppliers in Michigan for OEM engineering buyers”
  5. 5“Which Michigan spring manufacturers can produce aerospace-grade springs to MIL-spec requirements”
  6. 6“List 20 industrial springs companies in Michigan 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.
