About DEM Manufacturing

Design Engineering Manufacturing (DEM) is an original equipment manufacturer (OEM) that specializes in designing and manufacturing small, rugged molded electronic components. Our talented team carries a reputation for developing and producing innovative high-quality products that exceed customer expectations, which has led to an expansive number of long-term relationships over our 26-year history.


DEM was originally formed to design and manufacture products used to upgrade commercial grade radio components to meet Firefighting/Military Grade standards. In less than three decades, DEM has developed into a complete turnkey solution for companies looking to take their design concepts through a rigorous development process, guiding clients through prototyping, pre-production, product launch, and ensuring their ability to maintain a reliable supply source.


At DEM, we offer innovative solutions to our customers, while providing them with the expertise required to successfully design and launch new products into the market. Having adapted to our customers’ needs, we now design and manufacture highly specialized, custom-built communications cabling and connectors, injection molded housings, voice amplification modules, push-to-talk (PTT) devices, circuit boards, and other assemblies. Focusing our attention on the process, DEM has developed best practices to be able to offer a reasonably priced solution while keeping tooling and start-up costs to a minimum. In some cases, DEM is even willing to make the investment to design, engineer and fabricate tooling for our customer’s projects thereby eliminating upfront costs to our customers. DEM prides itself on being a flexible, agile, turnkey manufacturer, and no project is too large or too small.

Our customers range from small companies to organizations with a global reach, and include market leaders in communications devices used in industrial, government, and tactical applications. We also serve the medical device community, first-responders, and the energy and industrial markets. Our customers are time-sensitive and depend on DEM to deliver their products on schedule and with uncompromising quality.
