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 metal stampings companies in Illinois”
2“Who supplies custom progressive die metal stampings in Illinois”
3“I need a Illinois metal stampings partner for a 100,000 unit appliance bracket run, who should I talk to”
4“Top metal stampings suppliers in Illinois for automotive OEM buyers”
5“Which Illinois metal stampings companies can handle high-volume stainless steel progressive die work”
6“List 20 metal stampings 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.
