Universal testing machines from 1 kN to 250 kN

These universal testing machines are specifically designed for demanding testing situations and are suitable for applications from all fields, whether for quality control or for research projects. Zwick universal testing machines are developed, produced and assembled exclusively in Germany. All universal testing machines can be modified as required to suit individual requirements.

AllroundLine universal testing machines 

AllroundLine universal testing machines for individual testing requirements and all applications

The new AllroundLine universal testing machines are suitable for applications in all fields. A proven operating concept combined with flexible, modular load-frame design guarantees an optimum solution for demanding testing applications, whether in quality-control testing or as part of research projects.



ProLine universal testing machines for standardized tests

The two-column ProLine universal testing machines are specifically designed for function-testing components and for routine materials testing. They feature precision guidance and a low-wear ball-screw, allowing trouble-free tensile and compression testing.



cLine - first choice for testing automotive seats

cLine materials testing machines are especially suitable for component testing and for testing flexible foam materials. Component testing mainly takes place on flexible foam products such as mattresses and vehicle seats and upholstery.



Electromechanical testing actuator

These all-purpose electromechanical testing actuators are suitable for tensile and compression applications and can be integrated into testing devices in various configurations.


Single-screw testing machine 

Single-screw testing machines

Single-screw testing machines are used primarily for tests which impose particularly severe demands on load-frame stiffness.


Kappa creep testing machines 

Creep testing machines

Our 'Kappa' range of creep testing machines combine high precision with versatility for maximum cost-effectiveness.



Strength is a defined mechanical material characteristic which characterizes the resistance of the material to deformation, whether elastic or plastic. It is the stress calculated from the maximum force attained for a defined strain or a defined flow-property with reference to to the original (non-deformed and non-loaded) cross-section of the material.

Strengths are differentiated according to whether the loading is uniaxial or multiaxial, then whether a static or dynamic load is applied to the component; a certain amount of elastic strain or plastic deformation of the specimen can be predefined or may be involved.

If strains are measured on a component according to forces applied in different ways, graphs will be obtained from which the technically relevant strength characteristic values can be determined and stress-strain diagrams produced. Tensile hardening curves from a single-axis tensile test are regarded as particularly important in this context. Different strengths can be achieved depending on the type of material and the condition of the material, together with the temperature, load and loading rate.

Distinctions are made:

  • according to the type of load applied: static and dynamic loading, for example static, increasing, fatigue life or fatigue limit, in contrast to continuous loading: fatigue strength; fatigue strength
  • according to the mechanical loading, including tensile strength, compression strength, flexure strength, torsional strength, bulk strength and shear strength.
