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 tool and die companies for stamping, casting and forging dies in California”
2“Who supplies precision progressive stamping dies for high-volume automotive parts in California”
3“I need a California tool and die partner to design and build casting and forging dies for a new heavy equipment line, who should I talk to”
4“Top tool and die suppliers in California for stamping, casting and forging dies for OEM buyers”
5“Which California tool and die makers can handle large progressive dies with in-die sensing and quick-change inserts”
6“List 20 tool and die companies in California 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.
