The Capacity to Handle What Others Can't

When a part is too large or too complex for most shops in your area, your options get limited fast. You're either stuck waiting on a distant supplier or settling for a shop that's working outside its comfort zone.


We built our large-scale milling capability to solve exactly that problem. Our large-format machines give you:


  • Oversized work envelope — components that won't fit on standard equipment fit here
  • Heavy stock milling for thick raw material and structural components
  • Multi-axis capability across large surface areas and complex geometries
  • Consistent tolerances at scale — not just on small, easy parts
  • Prototype and production runs — we take small-run work seriously, not as filler
  • DFM feedback upfront — if we see a manufacturability issue in your STEP or DXF file, we call you before we cut, not after

What You Can Count On

Welding Icon

Tolerances Held At Scale

Large scale parts don't get a pass on precision. Our machinists hold tight tolerances across the full work envelope — the same standard we apply to every job on the floor.

Clock Icon

2-Week Lead Time

We know what a missed delivery does to your production schedule. Two weeks is our standard, and we stand behind it.

Quality Icon

Quality Management System Registered To Iso 9001:2015

Our quality management system is registered to ISO 9001:2015 through EAGLE Registrations Inc. That means documented processes and consistent results built into how we operate — on every job.

No Outsourcing Icon

No Outsourcing

Every part is machined in our 60,000-square-foot Nappanee facility by our own team on our own equipment. When you call to check on a job, you're talking to the people actually running it.

Family Icon

You're Not A Ticket Number

We're a family-owned shop. Ken Mullet has been running this business since 1994, and four of his children work here alongside him. When you call, someone picks up. When we quote you, it's a straight number — not a runaround.

Serving Northern Indiana Manufacturers

We're in Nappanee — close to the manufacturers we serve in Elkhart, Goshen, South Bend, Mishawaka, Fort Wayne, Warsaw, and Columbia City. Large parts are expensive and complicated to ship long distances. Keeping your supply chain local means faster turnaround, easier communication, and the ability to stop by if you need to.
