At APA, all of our associates work very closely and share knowledge about customers and projects. Accordingly, there is always someone who is ready and able to help our customers.


In addition to a warehouse facility in Nogales, AZ (not currently under the scope of ISO 9001:2005 and AS9100D standards), American Precision Assemblers has plants located in Hampshire, IL, Normal, IL, Hermosillo, MX and Duluth, MN. The facility in Duluth, MN has its own separate certified quality management system following ISO 9001:2005 and AS9100D standards. Outfitted with the same equipment, plus uniform systems, training and processes, all plants are capable of delivering high quality products to our customers.
