HOW KUK MASTERS CHALLENGES
IN COIL PRODUCTION

Why leading OEMs have already embraced KUK magnetic coils: because precision, speed and reliability are not optional extras in modern coil manufacturing, but essential requirements.

  • Imprecise magnetic fields, unstable field strength, nonuniform windings
  • Long delivery times for prototypes and modifications
  • No project partner on equal footing, frequently changing contact persons
  • Different suppliers for development, production, and series manufacturing
  • Quality variations between batches
  • High unit costs for small series
  • Limited choice of materials and geometries
  • Lack of documentation/traceability

FREQUENTLY ASKED QUESTIONS ABOUT MAGNETIC COILS

A magnetic coil is an electrical coil made of insulated copper (or alternative) wire that generates a magnetic field when current flows through it.
It is used in numerous industrial applications – for example, in sensors, valves, actuators, electromagnets, and inductive measuring systems.
The type of winding, the coil housing and the core (magnetic or non-magnetic) allow the magnetic field to be specifically controlled and optimised for the application.

We develop and manufacture customised magnetic coils, including:

  • Magnetic field coils for laboratory and measurement technology,
  • Electromagnet coils for actuators and valves,
  • Micro coils for medical technology and sensor technology,
  • Induction and special coils for research and development.

Each coil is individually adapted to the electrical, thermal and mechanical requirements of your project.

Our in-house development and manufacturing department enables fast prototype delivery within a few days – depending on complexity and material availability.
Automated processes and short decision-making paths enable us to significantly reduce your time to market.

Yes – we produce everything from single units to large series.
Individual items, test series and small series are particularly important in the development phase in order to validate the design.
Our production is designed to scale quickly from prototype to series production.

Our magnetic coils are used worldwide in various industries:

  • Industry & mechanical engineering
  • Automotive & electromobility
  • Sensors & measurement technology
  • Medical technology & life sciences
  • Aviation & defence

Both coil types generate magnetic fields, but differ in their design and application:

  • Magnetic field coils are mostly used to generate precise, homogeneous magnetic fields for measurements or experiments.
  • Electromagnet coils are designed for moving or force-transmitting applications, e.g. in actuators, valves or grippers.

Depending on the area of application, we adapt the geometry, core material and winding density to achieve optimum field behaviour.

We process a wide range of high-quality materials – precisely tailored to your specifications (function, temperature range and environment):

  • Conductor material: copper, aluminium and much more.
  • Core material: ferrite, iron, permalloy, soft magnetic alloys, etc.
  • Insulation material: polyimide, enamel, high-temperature varnishes, etc.
  • Coil former: plastic, ceramic, aluminium or customer-specific materials
    On request, we can supply RoHS- and REACH-compliant materials with complete documentation.

Our production is ISO-certified and follows strict quality processes.
Each coil is electrically and visually tested, including:

  • Resistance and inductance measurement
  • High voltage and insulation testing
  • Dimensional control and microscope inspection
    All batches are traceably documented – from the material batch to the final inspection.

Yes – please send us your drawings, 3D models or data sheets (e.g. STEP, DXF, PDF).

Our engineers will check the feasibility and advise you on design optimisations, material selection and manufacturing tolerances.

In addition to pure production, we offer:

  • Development & simulation of magnetic fields
  • Material consulting & design optimisation
  • Prototyping & testing
  • Series production & quality assurance
  • Logistics & just-in-time delivery
    This means you get everything from a single source – from the idea to the finished magnetic coil.

Yes – we supply customers on every continent worldwide.
Our logistics are designed for international OEMs, including customs-compliant documentation and export processing.
