LEONI production technologies in cable assembly:

Our extensive expertise, the training and qualifications of our employees and the equipment installed at our production facilities worldwide enable us to offer different joining techniques for the secure assembly of our cables:

  • Cutting, including stripping, as well as in-phase cutting and laser stripping
  • Crimping
  • Soldering, including induction, reflow and hot bar soldering
  • Cutting/clamping
  • Ultrasonic welding
  • Casting using hotmelt technology
  • Encapsulation using injection moulding technology
  • Assembly of optical silica fibers, glass fibers, plastic fibers, plastic-coated fibers and fiber bundles
  • Assembly of high-voltage cables
  • Moulding of liquid silicone rubber (LSR)
LEONI employees worldwide dispose of numerous manual joining techniques in the assembly of symmetric, coaxial, hybrid and miniaturised cables.</br>
LEONI avails of different semi-automated moulding techniques using thermoplastics, thermoplastic elastomeres and liquid silicone rubber (LSR).

LEONI production technologies in cable production:

The structure, shielding and materials used are of decisive importance for the mechanical and electric properties of a cable. Our extensive fleet of machines in our worldwide production facilities enable the production of a broad range of production processes for finishing our cables. As well as small external diameters, the requirements of your application are also taken into account.

In addition to

  • the extrusion of all thermoplastic extrudable plastics and special materials developed in our own materials research facility,
  • stranding with a defined slope and position of the wires,
  • wrapping with different shielding materials,
  • wire spinning with spiral-shaped wires and wires installed in parallel and
  • braiding to ensure precisely defined solidity

we also offer special shielding, foaming and wrapping technologies:

The combination of different shielding technologies allows for excellent electromagnetic shielding.

Thanks to the extremely stable and uniformly structured dieletrics of our wires (LEONIzell) in the skin-foam-skin extrusion, the transmission properties of a cable are optimised and very narrow diameters are achieved.

Wrapping technology enables us to produce dielectrics from ePTFE with a dielectric constant of up to 1.3 and excellent mechanical properties with the smallest external diameters.
