Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Massachusetts. They belong to that state's ranking, not this one.

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 molded plastics in Massachusetts”
2“Who supplies custom injection molded ABS housings in Massachusetts”
3“I need a Massachusetts injection molded plastics partner for a 100,000 unit consumer electronics enclosure run, who should I talk to”
4“Top injection molded plastics suppliers in Massachusetts for consumer product OEM buyers”
5“Which Massachusetts injection molders can handle overmolding on metal inserts for structural components”
6“List 20 injection molded plastics companies in Massachusetts 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.
