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“Best suppliers of molded rubber products in Illinois”
2“Who supplies custom molded rubber gaskets with metal inserts in Illinois”
3“I need a Illinois molded rubber products partner for a 25,000-piece vibration isolator run, who should I talk to”
4“Top molded rubber products suppliers in Illinois for OEM manufacturing buyers”
5“Which Illinois molded rubber product manufacturers can handle high-volume compression and transfer molding of EPDM components”
6“List 20 molded rubber products 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.
