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“Best plastic extrusion and thermoforming companies in Michigan”
2“Who supplies custom extruded and thermoformed plastic profiles in Michigan”
3“I need a Michigan plastic extrusion and thermoforming partner for a new consumer product housing program, who should I talk to”
4“Top plastic extrusion and thermoforming suppliers in Michigan for OEM product development buyers”
5“Which Michigan plastic extrusion and thermoforming companies can handle tight-tolerance co-extruded sheet and deep-draw forming”
6“List 20 plastic extrusion and thermoforming 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.
