About Northern Indiana Axle
Built on a 1994 Bet: That American CNC Still Had a Future 🇺🇸
In 1994, Ken Mullet bought his first CNC machine and started cutting metal in Nappanee. He's still here. So are four of his kids. So is every part we make — nothing outsourced, nothing offshored, every job run on our floor.
How It Started
Ken Mullet bought the business in 1989 after working for several years in the fencing industry. Fencing is seasonal work, and Ken wanted something he could build year-round. That search led him to the shop that would become Northern Indiana Axle.
Despite the name, the company makes a lot more than axles. Customers come to us for buggy axles, cable and hitch products, gun components, and a wide range of precision machined metal parts. Our team also works directly with customers on engineering better parts — offering design-for-manufacturability feedback before a single chip is cut.
A 60,000 Square Foot Shop in Nappanee
Northern Indiana Axle started in a 7,500-square-foot building. In April of 2014, we expanded to our current 60,000-square-foot facility in Nappanee. The bigger footprint also gave us the room to keep adding machines and capacity as demand grew.
Every part we make is machined right here — on our machines, by our employees, in our Nappanee facility. No outsourcing. No overseas shortcuts. 100% American-made.
Quality You Can Verify
Northern Indiana Axle operates a quality management system registered to ISO 9001:2015 through EAGLE Registrations Inc., accredited by the ANSI National Accreditation Board (ANAB). That registration isn't a marketing line — it's a documented commitment to consistent processes, traceability, and continuous improvement on every job that leaves our floor.
We are also a proud member of the Precision Machined Products Association (PMPA), the national trade association representing precision machining companies across North America. PMPA membership keeps our team connected to the latest standards, training, and best practices in the industry.
