If you’ve ever ridden in an SUV, you likely have first-hand experience with Mills Products. Our Tier 2 manufacturing facilities in the United States and Mexico produce automotive assemblies and sub-assemblies for most sport utility and crossover vehicles built in North America.

Automotive part designers come to us to make their parts lighter, stronger, and more cost-effective to produce. Even if your design is finalized, we may be able to help you improve a part you’ve been extruding for years through roll forming, hydroforming or tubular stamping.

Roll Forming

Our fully integrated inline roll forming process minimizes part handling and reduces costs. Inline sweep rolling and arc rolling allows us to create complex, aesthetically superior parts, including:

  • Automotive cargo shades
  • Bumpers
  • Side impact beams
  • Decorative trim
  • Chassis components
  • Window components


The first time you see a hydroformed stainless steel exhaust component, you’ll wonder why they’re manufactured any other way. Hydroforming’s design flexibility and high strength-to-weight ratio makes hydroforming the ideal solution for automotive components such as:

  • Manifolds
  • Exhaust cones
  • Engine cradles
  • Heat shields
  • Baffles
  • Dash structure

Tubular Stamping

Virtually any tubular part can benefit from an upgrade to tube stamping. This relatively new technology offers Class-A finishes without secondary machining, as well as significant weight-reduction opportunities. Common parts include:

  • Bushings
  • Sleeves
  • Tension sleeves
  • Tubing
  • Stand-offs
  • Roll pins

Choosing Your Metal Forming Process

The best method depends on your application. Our design engineers work with yours to determine which metal forming process will achieve the best results. We specialize in helping automotive manufacturers find solutions to meet their form, fit and function requirements in ways that cut costs and improve part strength.
