Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). At PRUFREX, single-chamber and multi-chamber coils can also be achieved using two-wire windings. For specific magnetic flux requirements, we apply wires of different thicknesses to the coil form. Two different wire thicknesses, from 0.045 to 0.71 millimetres, on coil forms with press-in ferrite or metallic cores.

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). We can wind onto any desired coil form using many different press-in ferrite and metallic cores. Multiple tap coils are also possible. Pins are automatically applied to the coil connections during the winding process, with wire drawing electrically controlled. Our winding machines handle single-chamber and multi-chamber coils with wire thicknesses from 0.045 to 0.71 millimetres.

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). To manufacture self-supporting coils, we use self-bonding wire. During winding, the surface of the wire is bonded using hot air. To ensure the coil connections can be soldered, they are then stripped of insulating enamel using a fully automated milling process. PRUFREX is able to make air core coils with wire thicknesses from 0.045 to 1.6 millimetres.

Alongside the standard ICT/FCT process, we can also target every individual production stage for verification, as requested. Efficient inspection strategies and final functional tests are a fixed component of our quality management system. This electrical test process is ideal for testing smaller numbers of units, such as for pre-production, prototype or pilot series. The rapid test creation process allows, among other things, flexible reaction to product changes. Flying probe tests can be rapidly set up and are cost-efficient.

Alongside the standard ICT/FCT process, we can also target every individual production stage for verification, as requested. Efficient inspection strategies and final functional tests are a fixed component of our quality management system. In our test laboratory, we are able to carry out static and cyclical environmental simulation for you, from air-to-air and liquid-to-liquid thermal shock tests to storage temperature and humidity tests. Based on the environment in which the product is to be deployed, we will draw up a tailor-made quality assurance programme. Through simulation of the conditions that cause ageing (e.g. large temperature fluctuations) we can ensure that the product will reach the required service life. Products are also subjected to further customer-specific tests in fields such as EMC, overload resistance and mechanical loading.
