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 injection molds and mold making in Ohio”
2“Who supplies multi-cavity hardened steel injection molds for high-volume production in Ohio”
3“I need a Ohio mold making partner for a new plastic enclosure program with frequent engineering changes, who should I talk to”
4“Top injection molds and mold making suppliers in Ohio for custom plastic product manufacturers”
5“Which Ohio mold makers can design and build complex hot-runner injection molds with tight-tolerance inserts”
6“List 20 injection molds and mold making companies in Ohio 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.
