We offer our customers a long term commitment from sales to technical back up and believe our after-sales service to be second to none. Our operation utilises the latest in coil winding technology such as computer-controlled winding machines and automated assembly equipment. This, coupled with our purchasing power gives us the flexibility to keep costs low while retaining high standards.


Production and Build

At JM Transformers, our highly trained team have all the experience necessary to carry out virtually any coil winding solution. Our strength lies in producing perfectly wound coils (layer wound) and complex switched mode transformers.

With many years experience within the coil winding industry we have developed a range of machinery and tooling specifically designed for high accuracy, repeatability and high speed production of even the most complex of windings. In particular we are one of a few manufacturers that can deal with miniature windings, of which the applications include hearing aids or pick-up cartridges. We can wind these products using wire as small as 0.01mm.

JM Transformers also have a fully equipped tool room to make custom tooling solutions to build your bespoke products and all units are fully tested using the latest equipment.

Quality Control

It is a fundamental belief at JM Transformers, that quality at every stage of our business is essential to maintain the ongoing satisfaction of our customers and our survival in the market place.

Quality is built into the products we produce as standard. Because we understand the need of our customers we can select the best materials and design in performance and longevity well in advance of any unit production. Repeatability of units is controlled by our in-house procedures, and the use of computer controlled machines and automated processes.

This coupled with our quality system – maintained to ISO9001 : 2000, ensures that our customers get the product they require on the day they require it, in the condition they have come to expect from us.
