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 metal finishing services companies in Massachusetts”
2“Who supplies precision metal finishing for small stainless steel components in Massachusetts”
3“I need a Massachusetts metal finishing partner for a 10,000 piece medical device housing run, who should I talk to”
4“Top metal finishing services suppliers in Massachusetts for industrial OEM buyers”
5“Which Massachusetts metal finishing service providers can handle high-volume automated line finishing with tight cosmetic requirements”
6“List 20 metal finishing services 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.
