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