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 plastic extrusion and thermoforming companies in Wisconsin”
2“Who supplies custom extruded and thermoformed plastic profiles in Wisconsin”
3“I need a Wisconsin plastic extrusion and thermoforming partner for a new consumer product housing program, who should I talk to”
4“Top plastic extrusion and thermoforming suppliers in Wisconsin for OEM product development buyers”
5“Which Wisconsin plastic extrusion and thermoforming companies can handle tight-tolerance co-extruded sheet and deep-draw forming”
6“List 20 plastic extrusion and thermoforming companies in Wisconsin 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.
