Fabricating and Machining of Plastic, Carbon Fiber and Metal Components

Dielectric Manufacturing maintains a wide variety of CNC machining and other equipment at three locations in Wisconsin and Iowa for any machining or fabricating need. We regularly invest in new equipment to meet the needs of our customers for precision metal, carbon fiber and plastic parts and assemblies – allowing us to be a true contract manufacturer.

mri phantomsWe work with a wide variety of materials, including thermoplastics, thermoset plastics, composites, and ferrous and non-ferrous metals, including exotic alloys. Based on our experience with those materials, we can recommend the right plastic or metal material for your application, or recommend alternative materials for your custom parts. For metal parts, our Metro Milwaukee location in Richfield, Wis., machines parts from non-ferrous metals while our Central Wisconsin plant in Waupaca, Wis., machines parts from ferrous metals. We primarily do CNC machining rather than injection molding.

Wide Range of Fabrication, Machining Equipment

Our machining and fabricating equipment allows us to offer milling, turning, routing, etching, saw cutting, drilling and tapping, stamping and punching, solvent bending, and UV bonding – providing parts that meet tight tolerance requirements.

custom machined metal partBased on our 55+ years of experience, we are often able to make design and material recommendations that provide for even greater efficiencies in machining and fabrication – efficiencies that benefit our customers.

Manufacturers in the health care, aerospace, agriculture, electrical, military, gas and oil, power generation and distribution (including wind power), power sports, and food processing industries rely on the precision we are able to offer with our equipment and design knowledge. But no matter what industry you are in, Dielectric Manufacturing will dedicate the same expertise, ability to meet tight tolerances, and quality control to provide precision, CNC machined parts and assemblies.
