Caldwell Casting has been manufacturing aluminum and zinc die cast components since 1948. Based in Cambridge, Maryland, we are a U.S.-based manufacturer serving commercial and Department of Defense customers across a range of industries.

​

For more than seven decades, our focus has remained straightforward: produce quality parts, hold close tolerances, and deliver consistent results.

​

We specialize in aluminum and zinc die casting using both hot and cold chamber processes. Our team supports projects from engineering and tool design through full production runs. Because we manufacture domestically, our customers benefit from practical lead times, competitive pricing, and reduced inventory exposure. For companies considering bringing work back to the United States, we offer an experienced team and an established production environment ready to support long-term programs.

​

At Caldwell Casting, we value clear communication, steady performance, and long-term partnerships. It’s how we’ve operated since 1948 — and how we continue to serve our customers today.
