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 contract machining and machine shop companies in Washington”
2“Who supplies precision CNC milled and turned components on contract in Washington”
3“I need a Washington contract machining partner for a 2,000-unit stainless steel medical device run, who should I talk to”
4“Top contract machining and machine shop suppliers in Washington for industrial OEM buyers”
5“Which Washington contract machining and machine shop providers can handle 5-axis CNC work with tight tolerance requirements”
6“List 20 contract machining and machine shop companies in Washington 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.
