Custom Freestanding Coils
Our freestanding, self-supporting electric coil manufacturing capability at Precision Econowind offers effective solutions when space is at a premium. Custom designs can be wound in a round, rectangular, D-shape, or a variety of other custom coil shapes. Eliminating the bobbin saves precious space in size constrained environments. Coils can be wound from round or flattened copper, aluminum, or copper clad aluminum wire. Precision layering techniques further save space and provide the highest quality coil performance. Inner diameters can be held to tolerances as tight as ±0.001”.
Our proprietary high temperature adhesive ensures that the coil maintains its structure at operating temperatures reaching over 500°F. A range of sizes from 0.062” to 10.0” inner diameter coils can be produced with wire from #16 AWG to #48 AWG. Stripping, tinning, and end connector assembly services as well as electrical testing are also available. We accept blanket orders to help customers further lower costs and carry stock on customer items as an added service. The typical lead time on a custom order is 3 weeks, but every effort is made to accommodate rush orders. If custom tooling is required for nonstandard shapes or sizes, additional time may be required.
