Contract Manufacturing
Flexible, High-Quality Assembly Solutions for Your Operation
At Prairie Electric, we provide contract manufacturing services for non-UL listed electro-mechanical assemblies of all types and complexity levels. Whether you need one build a year or thousands, our team can handle it: sourcing components, managing logistics, assembling parts, and delivering them when and where you need them. From PLCs, HMIs, relays, and sensors to custom wire harnesses and cable assemblies, we build the parts and systems that keep your operation running.
Your Partner in Streamlined Production
Our contract manufacturing team takes the burden of sourcing, building, and storing components off your plate. We can work directly from your detailed drawings, reverse-engineer from a “golden sample,” or help you create and maintain documentation so you always know exactly what you’re getting. Whether your needs are electrical, mechanical, or a combination of both, Prairie Electric has the experience, resources, and precision to deliver.
We can integrate custom sheet metal or plastic assemblies from our trusted suppliers, handle in-house builds, and even develop or update engineering drawings for ongoing production. Our goal is simple: make your process easier, faster, and more reliable.

- Full Assembly Builds: From simple ground straps to complex box builds with component programming.
- Cable and Wire Harness Assemblies: Low- to high-volume production in varying complexity levels.
