Founded in 1905, M.D. Hubbard Spring Co., Inc. has evolved from manufacturing leaf springs for buggies and harrows for plows to processing modern, high-precision metal components for automotive, aerospace, medical, heavy truck, agriculture, and industrial customers worldwide.
Originally established in Pontiac, Michigan, the company relocated to its current Oxford, Michigan facility in 1973. Following a major expansion in 2016, the facility now encompasses 50,000 square feet of manufacturing space.
Since 2020, we have transitioned production of both standard and custom product lines to CNC-controlled stamping and forming equipment. By digitally controlling process variables and machine movements, we achieve faster setup times and improved lot-to-lot quality and consistency. This investment has also helped us train and develop the next generation of manufacturing professionals. Combined with our in-house tooling capabilities, these technologies allow us to quickly respond to customer requirements while maintaining exceptional quality and manufacturing flexibility.
We are dedicated to building a long-term manufacturing enterprise in Oakland County, Michigan, focused on continuous improvement, skilled craftsmanship, and lasting customer relationships for generations to come.
