Expert Engineering &
Machining Capabilities

We create (and recreate) the parts you need for the rail industry, steel mills, manufacturing plants, and beyond. All manufacturing work is done in-house at our full-service facility.

Reverse Engineering

Do you have a broken or worn out part that needs replacing but is no longer manufactured? Don’t bother with inferior substitutes or be forced to replace the entire assembly — we can reverse engineer your old part and recreate it using a comparable or stronger material.


Our extensive metalworking expertise covers all your needs: machining, welding, fabrication, and technical services. We can refurbish machines, create new items from spec sheets, develop custom designs, and more. Our machining capabilities include:

  • Two (2) Cincinnati Milacron Vertical Machining Centers
  • Cincinnati Milacron Horizontal Machining Center
  • KAAST Machining Center
  • 20-Foot Planer Mill
  • Multiple Monarch Lathes
  • Giddings & Lewis 5-Inch Horizontal Boring Mill


Everything we do begins with a simple question: how can we make this better? Rather than simply accepting the way things have been done in the past, our business is based on innovation — solving problems brought to use by clients, or coming up with solutions to challenges we’ve observed in our years of experience in the rail industry.
