Dielectric Manufacturing is a single source for plastics and metals contract manufacturing and services, committed to delivering world-class solutions.

We offer machining, fabrication and value-added services on a wide variety of materials, including thermosets, thermoplastics, carbon fibers, and ferrous and non-ferrous metals at three locations across Wisconsin and Iowa. Additionally, we can be your source for purchasing unfinished materials.

The advantages of plastic contract manufacturing include:

• access to specialized expertise,
• reduced costs and time-to-market,
• improved production efficiency, and
• scalability.

Additionally, contract manufacturing allows companies to focus on their core competencies and leave the plastic manufacturing to the experts, like Dielectric Manufacturing.
