Premium extrusion equipment
and intensive process know-how for fluorine and high-performance plastics
premium machinery for special cable production
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

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.
your specialist for manufacturing solutions for special cables
thinner than a human hair
production equipment for micro-coaxial cables
With our special wire extrusion equipment, you can process micro-coaxial 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.
