Ensuring longevity

In order to make good on our company claim and motto “LEONI – The Quality Connection”, we are continuously investing in the improvement of our instrumentation.
 The reliability and performance of our cables and cable systems are tested in a range of processes designed to verify their longevity.

Methods of cable testing

Mechanical tests specifically designed for cables

Insertion test

to determine mating cycles and forces

Temperature and ageing test

to examine long-term behaviour under
 specified conditions

Visual measurement

of the components

drag chain test centre

Drag chain tests

In our own drag chain test center, drag chain test are conducted. Here the long-lasting mobility of our cables is tested. Our test routes have different traverse paths, accelarations and movement speeds. Each test system can test up to 40 cables over the equivalent of several years. The longest traverse path measures 50 m.

Torsion tests

In different torsion and torsional bending machines, the cables are tested for twisting and traction around their own axes. They are subjected to a torsional movement of up to +/- 360° in lengths of 0.3 to 1.0 m.

Flexional tests

In test systems with rolls for different bending radii, a test is performed to see whether the cables can withstand frequent bending cycles. The used rolls have a diameter of 20 to 250 mm.
