Ace Manufacturing Building

AMI was founded by Tom Krouth in 1992, initially employing only 5 staff in a 4,000 square foot building. What began as a small machine shop has since flourished into a thriving business, with 100 employees and an 88,000 square foot facility. We are still a family owned business today.

Machining, assembly, hydraulic testing, and painting are just some of the services our engineers are trained to carry out to the most exacting standard. These services allow us to provide our customers with a single source for custom manufactured parts. By providing all of these services under one roof, we are able to reduce shipping and handling costs for our customers.
