We are Obsessed With Quality

In the 50-plus years that we have been manufacturing coils, Preformed Windings has developed an exceptional reputation for the quality of our products. This is the primary reason why we have become the largest independent coil manufacturer in the world, supplying quality coils to independent repair shops and OEMs alike. We are ISO 9001:2015 certified and operate ISO 18001:2015 quality systems. We manufacture coils to standards such as BS EN 50209:19999, ESI 44-5, as well as customer-specific standards. Due to our international presence, we have experience manufacturing coils to regional standards worldwide.

  • We only use the highest quality and most respected suppliers of copper and insulation.
  • Preformed Windings have invested heavily in the most cutting-edge equipment, both automated and semi-automated.
  • Experience working with the industry’s largest OEMs developing coil specifications.
  • Hundreds of years of experience within our team.
  • 3D CAD software allowing analysis and optimization of coil designs prior to manufacture.
  • In many cases, we can offer an improved coil design (at no cost) in order to optimize efficiency and operating temperatures.
  • Extremely uniform coils resulting in a reduction in winding time.
  • Very tight geometrical tolerances; in many cases, our customers move away from side packing coils.

  • Every coil tested prior to dispatch.
  • Coils delivered in heavy-duty wooden boxes designed specifically for the location they are being dispatched to.
