Material & Component testing

Testing materials and components is an important step in checking the functionality and correctness before delivery to the customer. If necessary we check the delievered parts first. But newly developed elements have to be tested in many cases for whether the targeted parameters have been achieved.

There are different methods for material and component testing. You have to distinguish between destructive and non-destructive testing. Non-destructive material testing is suitable when it is not possible or appropriate to destroy stock samples or full parts. This can be the case with technical installations, machinery and different vehicles.

With non-destructive tests damage such as cracks, flaw, and corrison or material fatigue can be recognized early. With complex components it is important that possible imperfections can be limited. In each case non-destructive material testings can be while a machine is running.

Non-destructive material testing is suitable when it is not possible or appropriate to destroy stock samples or full parts. This can be the case with technical installations, machinery and different vehicles.

With non-destrucive tests damages such as cracks, flaw, and corrision and material fatigue can be recognized early. With complex components it is important that possible imperfections can limited. In each case non-destructive material testing can be while a machine is running.

Furthermore testing procedures like those are the only possibility to check the different joints (gluing, welds, shrinking, etc.) for precision and partly for strength.

Machines for mechanical testing

Roell Amsler testing machine HC 10

With this machine mechanical weights can be put on dynamically (endurance test):

  • Force range:  +/- 10 kN
  • Psiton stroke: 100 mm
  • Extensometer: 5 mm, 20 mm, 50 mm
  • Testing frequency: max. 75 Hz (sinus, triangle, trapezium, rectangle, ramp)
  • Regulation: force, displacement, external sensor
  • Table surface: 400 x 400 mm

The analysis of the force-displacement curve from a temporal point of view helps to bring out signs of fatigue.

Universal testing machine Shimadzu/Hegewald & Peschke AG-250kN G/S

  • Load sensor: +/- 5 kN, +/- 250 kN
  • Wedge and hydraulic clamps
  • Bending bench: 1000 mm, 150 mm
  • Extensometer: 10 mm, 2 mm
  • Table surface: 300 x 570 mm
  • Beam stroke: 13540 mm
  • Movement speed: 0.05 ... 500 mm/s
  • Regulation: force, displacement, stretching
  • Tests: tensile, pressure, bending, tensile shear, peel and disconnection test


The most important evaluation form of the tests is the determination of the modulus of elasticity, flexural, tensile and pressure modulus etc. as well as force-displacement diagram curves.
