Winding technology for coreless coils and coils on bobbins.
Custom solutions, Individual parts or small-scale series we produce what makes sense from a financial point of view.


As part of machines and systems, magnetic coils serve a wide variety of tasks in motion technology. Whether as a brake magnet or as a clutch coil, magnetic coils are always the first choice for reliable operation in the transmission and control of torques.


As an electronic counterpart to the magnetic coil, inductances serve to provide current storage and smoothing capacities in the supply of electrically demanding circuit components. Here, too, core coils are very popular due to the particularly lossless winding technology and offer a wide range of applications.


Coils meant to be built in drive units or housings are often spooled direct on an installation without a bobbin. Coils are stabilized by heating, the socalled baking of the coil.


In case that the coils are inserted into another module, or it is required by the necessary dimensions, the coils are wound direct on an L- or U-bobbin.
This bobbin ensures the stability as well so that baking is not necessary in any case.


In a further step the coils are extruded with plastic. With the closed casing the coil becomes a complete unit, that is inserted in the factory into other parts, or mounted in units in a customers machine


The raw coils are joint to strands or cables, and fastened to plugs and connections. A diversified bandaging and insulation completes the know-how.

Coil winding technology

One component is wire winding

The correct winding of the coils with the exact required number of windings is only one step in the manifold stages of production. Preceeded is the computation in regards of dimension, material and inductivity, the planning of connections and plugs, the construction of the coiling installations as well as the tools for the extruding of the bobbins and the jacket.

The raw coil is equipped with cables and strands, connected with plugs and connectors so that the coil is prepared for further processing. Usually all the steps in the production of a coil are proceeded inhouse on the shortest ways, with modern equipment and a maximum of experience, so that from the first meeting to the pilot production sometimes only some days or few weeks are necessary.
