OUR MAIN PROCESSES

DEVELOPMENT

The trafowerk Creuzburg not only manufactures according to specifications, we also support you in the design of components. For development and design, our engineers and technicians are happy to answer your questions.

Development support: Classic component design taking into account existing standards, mechanical design, production optimization for large series

Winding processes

With a targeted winding, the properties of an inductive component, such as efficiency or dielectric strength, can be influenced. With our know-how, we ensure that an optimal and cost-effective solution is used for your application.

Winding process: (Automated) linear winding technology, toroidal core winding technology, micro winding technology, ...

Semi-finished winding products: wire, HF strand, strip, flat wire, fine wire, ...

Winding materials: copper, aluminum, ...

FINE MECHANICAL PROCESSES

In addition to the winding technology itself, the mechanical processing also forms a part of the component production, in order to give the winding goods the suitable form, which ensures the suitability for use in the respective application. We also manufacture special housings made of Mu-metal specifically for your needs.

Shaping methods: Block casting, injection moulding, 3D printing, ...

Forming technology: Punching, bending, turning, milling, drilling, grinding, ...

Bonding and adhesive techniques: Mounting, pressing on and pressing in, welding, soldering, adhesion, ...

PROTECTION AND EMBEDMENT

Optimum protection for every application. Whether impregnation, treatment or socketing: Benefit from more than 40 years of experience in the application of these technologies.

(Vacuum) cast: Polyurethane, epoxide, silicone, ...

(Vacuum) impregnation: Alkyd resins, polyester imide resins, epoxide, ...

Pre-treatment techniques: Degreasing, sandblasting, plasma activation, ...

Parameter inspection

In order to maintain a reproducible quality, all components are distinguished by their electrical values during sampling and examined during the series production. The measurement conditions are adjusted to the respective deployment conditions and co-ordinated with the customer.

Classic measurement methods: Resistance, inductivity, leakage inductance, transmission ratio, capacity, resonance frequency, group delay, ...

Low-level parameters: Insertion loss, return loss, ...

Measurement in customer application: e.g. sensor calibration (speed, pressure, magnetic field)

100% safety inspection

Not only the obligatory insulation test is carried out on all components. According to the requirements and after consultation we carry out a whole series of safety inspections on the component in order to guarantee the reliability and longevity of your component.

High-voltage inspection: DC voltage up to 30 kV, AC voltage up to 5 kV

Partial discharge: Sensitivity 5 pC, up to 15 kV

Insulation resistance: 1 GOhm, voltage up to 1 kV 

Shorted coil inspection: Surge voltage up to 6 kV

Slow temperature test: -70°C to 200°C

Contacting technology

The reliable contacting of the electrical connections is essential for the function in an application. Our personnel are trained in this procedure. Trained specialists in accordance with IPC A610 and IPC A620 are at hand at all sites to guarantee the quality of the connections.

Soft soldering: Manual soldering, dip soldering, high-frequency soldering, resistance soldering

Brazing: Soldering iron, resistance soldering
