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 plating and electroplating services companies in Indiana”
2“Who supplies precision gold electroplating services for electronic contacts in Indiana”
3“I need a Indiana plating partner for a 25,000 piece zinc-nickel corrosion-resistant fastener run, who should I talk to”
4“Top plating and electroplating services suppliers in Indiana for industrial OEM buyers”
5“Which Indiana plating shops can handle rack and barrel electroplating on high-volume small parts”
6“List 20 plating and electroplating services companies in Indiana 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.
