Quarter Century of Excellence

Who We Are

We have great people. We have a great process. Over our 25 years, we have built a track record and client list that other contract assemblers envy. We are proud to offer a one-source solution to plan, build, fulfill and support products critical to growing businesses and those needing help to meet production challenges.

Through our network of facilities strategically situated throughout the Midwest, we assure on-time delivery of high-quality products that meet all specifications at a very competitive cost. CEOs, general managers, frontline supervisors, and other company leaders who need production help rely on us. They prefer to work with one company, not a collection of suppliers. We are that one company.

Why We’re Different

Many companies can work with you on your outsourcing strategy. But we have a proven process that transforms strategy into just-in-time delivery of your product, whether it’s a finished item ready for immediate use or a subassembly that is installation-ready. And we offer heavy truck upfitting services too, including the engineering it takes to custom-fit crane assemblies and railroad-accessory packages.

Our Engineering Change Response Team develops solutions to manufacturing issues as they arise, keeping projects on track for delivery. We can start and stop projects quickly. We’re comfortable with short-term and long-term agreements. In our process, customers can issue one purchase order and receive a single invoice for a completed assembly or upfitting project. We’re all about delivering the highest-quality product at the most competitive cost.
