Coils and solenoids - Import export

In coil manufacturing, the production of miniature air coils or micro coils is one of KUK's specialities. According to your specific requirements, we process ultra-fine wires from a diameter of 0.010 mm, which are suitable for a wide range of innovative applications. Thanks to integrated plant and tool construction, KUK Group has the capabilities to process ultra-fine wire from 10 µm and to produce micro coils with diameters from 0.3 mm. For miniature coils with magnetic cores, cores made of a wide variety of materials are possible, including mu-metal, ferrite or amorphous materials. Custom coil solutions can be developed with guide configurations for manual assembly or surface mount SMD coils for delivery in tape and reel, allowing automated reflow processes for PCBA. Our micro coils can be wound with copper, silver, gold or other wire alloys. Various coatings, overmoulding, packaging and test options are available.

Unlike air coils, bobbin coils, as the name already suggests, have a ferromagnetic body or coil former made of different material. The advantage of solenoid bobbin coils: higher inductances can be generated. Whether complicated to manufacture or adapted to special requirements - thanks to in-house winding lines, KUK produces the right bobbin coil for you. The bobbin coils are partly manufactured on standard coil formers. However, we mainly wind onto customer-specific coil formers. We wind bobbin coils from enamelled copper wire or alternative conductor material and thus achieve optimum results in customer-specific applications. We will be happy to advise you on the optimum core material for your solenoid bobbin coil. You can also benefit from our many years of cooperation with specialised suppliers. -Different winding methods -With pin mounting -Connection of litz wires, plugs, etc. -Twisted wire ends

KUK manufactures air coils for a wide variety of applications, e.g. RFID antennas, control coils or transponder coils. To produce self-supporting coils, self-bonding wire is also used, which is superficially bonded (glued) together during or after winding. Air coils are usually made of enamelled copper wire or high-frequency litz wire. So-called self-bonding wire is used to manufacture self-supporting air coils. It has an outer layer whose melting point is lower than the melting point of the insulation. After winding the air core coil, the turns of the coil are "baked" (glued) together by heating, usually by increased current flow. Thanks to our in-house plant engineering, we can optimally align our production lines to your needs, even for air core coils. - Ultra-fine wires starting at 0.020 mm - Single-layer flat coils in cylindrical or rectangular shape - single, bifilar or trifilar winding - Winding with HF litz wires
