Experience and expertise
pay off twice

There are fields in which cable products must deliver very special performance, like in medical, aerospace, and military technology, as well as in the automotive industry. They are used for oil pump cables, heating cables, or for any purposes that require specialty cables of a high-temperature class and with high chemical and mechanical stability.

When it comes to the production of special cables with special properties, the desired machine performance rises to a high level. Cable products manufactured on Rosendahl machinery are among the best in the world and perform incredibly well.

High flexibility with modular line concept

Manufacture a variety of communication cable designs for special use on one line

Lowest scrap for expensive materials

Save costs thanks to short start-up time and constant production processes

Excellent quality parameters

Produce cable with superior chemical, mechanical, and dielectric properties

profit from decades of experience

We can handle high-performance materials

High-temperature materials (FEP, PFA, ETFE, PEEK, TPI) cannot be processed in the same way as standard materials. Precise calculations and tool designs are necessary to prevent damage and achieve an optimum result. That requires a great deal of expertise and experience that we have been able to acquire over many decades. We are constantly researching new material compositions and refining our processes.

In addition, we maintain close relationships with suppliers of specialty materials. That gives us valuable insights into the market and first-hand knowledge of demand and parameters.

production equipment for micro coax cables

With our special wire extrusion equipment, you can process micro coax cables as small as 0.025 mm in diameter. A product with these properties is mainly used for high-end applications, e.g., in medical technology, aerospace, or military applications.

heat and fire resistant cables

When temperatures rise,
so do requirements

Can you imagine a cable that can withstand temperatures of up to 250 °C for several minutes? To meet this or similar requirements, every production step must be precisely coordinated.

Very small deviations are enough to change the properties of the materials used. Therefore, precise control of temperature and optimized equipment are key to an excellent final product. The core components – crosshead and extruder – have to withstand temperatures of up to 450 degrees.
