Dufrane offers a “Build to Print” capability to our more advanced customers.  If your engineering team has come up with a custom transformer or custom winding design for any electromagnetic component – we are more than happy to review the drawings, check the calculations and offer a quote for us to assemble the product at Dufrane.  Whether it’s a simple bobbin winding, or complex isolation transformer, toroidal transformer, current transformer or any small custom transformer, we can build it for you – AND offer our own engineering review to insure that the design is optimized for optimal cost, size, performance and manufacturability.

Dufrane’s experience qualifies us as a leading supplier of high reliability power solutions including custom windings, custom coils, small custom transformers, chokes, reactors, inductors, power transformers, current transformers, and other custom electromagnetic solutions.  We are experts in Build-to-Print manufacturing and test services for military applications, industrial applications, and electric utility/power grid support. Dufrane’s engineering staff offers value added service – we will review your design and offer suggestions / design changes to optimize the design for performance, longevity, and manufacturability (lowest cost while optimizing performance).
