Winding wires - Import export

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). 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.

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.

The range of application for the high-precision resistance decades models 1406 and 1407 stretches from reference standard for precision measurements up to simulation ot a host of measuring transducers. They can be used for control in complicated equipments and systems, such as equivalent circuit in resistor networks. Another application is the use in switching circuits, as reproducible variable in laboratory and test assemblies. The decade resistors meet all the requirements of these differing functions as well as the resulting demands. The high-precision resistance decades models 1406 and 1407 are designed to meet the highest demands with regard to precision, temperature and long-term consistency. Many years at experience, tried-and-tested technology and the use of fieldproven materials guarantee the high level of precision. The decade resistors consist of low-capacity and low inductance wire windings of MANGANIN®.

The fire protection bandage is used as cable insulation for individual cables, cable- and electrical installation pipe bundles (EIR). The insulation consists of a flexible bandage, fixed using wire. When surrounding the cables, take account of how often the appropriate medium must be surrounded. Refer to the approval for details. The bandage can be used directly next to Rockwool pipe insulation. Winding wire is included.

The perfect machine to quickly and automatically return the winding material remaining on the spools to the recycling process. The spools do not suffer any damage and can therefore be used over a long period of time. Device details: ▪ Enables up to 24 braiding spools to be unwound at the same time ▪ Appropriate spools: ▫ Diameter of mandrel 23 mm (standard version) ▫ Spool outer diameter up to 100 mm ▫ Other spools with different inner and outer diameters possible ▪ Suitable for different winding materials, e.g. metal wire, plastic, natural, glass and carbon fibres
