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 castings suppliers in California”
2“Who supplies precision machined aluminum die cast housings in California”
3“I need a California casting partner for a 10,000-piece hydraulic valve body run, who should I talk to”
4“Top castings suppliers in California for industrial OEM buyers”
5“Which California casting suppliers can handle complex thin-wall investment castings with secondary machining”
6“List 20 castings 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.
