The large igus® the-chain test lab

Reducing costs while guaranteeing the highest possible process reliability: only those who invest considerable resources in testing and research, such as igus®, can successfully address these competing requirements. In the industry's largest test laboratory, more than 10 million test cycles are carried out every year at 180 testing stations with e-chains® and chainflex® cables.
Our mechanical engineering components pass the "litmus test" presented by production reality, because they have already passed this test before they ever leave the igus® warehouse.
4,100 energy chain system tests annually at 180 test stations: climate chamber, outdoor tests, noise chamber, travel lengths up to 130m, robot systems etc.

Details of current tests

Cable wear virtually halved

Interior separation in e-chains®: Cable wear virtually halved under the toughest conditions.

Cleanroom tests

Pre-tests regarding cleanroom suitability in our own test laboratory.

Comparison of unsupported length

How does the unsupported length of the igus® e-chains® Series E2.15 and 08 differ under load?

Comparison test: E4.42, E4.48L and 3500

e-chain comparison test: E.4.42, E4.48L and 3500

Lighter energy chain with less sag

Noise test

Noise testing on P4 profile roller e-chain®

Offshore comparison test

Offshore energy chain for use on the seabed

Oil test with e-chains®

Ranging from metal chips to wood dust and fluids: we have the right solution for your energy supply system.

Rigid mounting brackets

Absorption of maximum bending torque on rigid mounting brackets, so that these function reliably even when exposed to lateral acceleration.

Series P4

Series P4 - endurance runner for long travels at high speeds.

Tensile and breaking test of the largest plastic e-chain®

The standard test machines are not strong enough to break the E4.350.

Tensile testing with energy chains in oil

Tensile testing with energy chains in oil

Test 2233 - CF5.10.25 control cable

CF5.10.25 control cable withstands 42 million strokes with a bend radius of 100 mm.

Test of E4.48L in comparison with competitor's product

igus® E4.48L and a competitor's product are tested with regard to unsupported length as well as tensile strength and resistance to breakage.

Test of e-chain® E4

chainflex® cables show no wear even after 222,776 cycles

Test report - e-spool®

The requirements regarding the permissible volume of noise produced by moving products in the stage area are very high.

What else is tested in the test laboratory?

In the igus® test lab, thorough examination is performed not only for the e-chain® components. iglidur® plain bearings, chainflex® cables, drylin® linear plain bearings and axes, lead screw systems and robolink® components are tested thoroughly as well.
