Kappa Multistation Creep Testing Machine

Space-saving and low cost testing solution for plastics testing.

The Kappa Multistation is a flexible, compact, high-precision electromechanical creep testing machine with individually controlled load axes. It was specially designed for the analysis of the creep behavior of plastics and polymer materials at modern R&D laboratories.

Key Advantages and Features

Advantages and features

  • Versatile creep testing system with 3 to 6 independently controlled load axes in one test frame
  • Extremely low cost and space-saving design with a robust test frame
  • Stepless force and temperature sequences, as well as force- and strain-controlled tests (closed loop) are possible
  • No influence on sensitive specimens with the use of non-contact strain measurement system according to the ISO 899-1 recommendation
  • A common temperature zone for all test axes with a temperature chamber of -70°C to +250°C
    Equipment option: a second temperature chamber for complete and profound analysis of the material properties at different temperatures, such as tests according to the stepped isothermal method (SIM)
  • Simulation of different environmental conditions (temperature and humidity control)
  • Use of high-precision load cells
  • Test monitoring and analysis with testXpert III software


This creep testing machine is the optimal testing solution for applications such as creep tensile tests and creep flexure tests on plastics to ASTM D2990, ISO 899-1 (tensile test) and ISO 899-2 (flexure test). Due to the versatility of this testing system, quasi-static tensile, compression, and flexure tests, as well as relaxation tests and expanded creep tests can also be performed on other materials. The Kappa Multistation is available in the measurement range of 5 N up to 50 kN per load axis and is often combined with an optical multistation strain measurement system and a temperature chamber.

Temperature Chamber and Non-Contact Strain Measurement with Kappa Multistation

Temperature chamber

  • Temperature range from -70 °C to +250 °C
  • Temperature tolerance from ±2 K to 150 °C
    Temperature tolerance from ±3 K to 250 °C
  • Self-supporting, double-wall stainless steel housing
  • View window with four-pane glass on the rear side of the temperature chamber for non-contact strain measurement with video extensometer
  • Optimal heat distribution via two heating coils and two fans (air flow principle)
  • Equipped with PT100 temperature sensor and Teflon bushings for upper and lower feedthrough of the load strings

Non-contact video extensometer

  • Intended for the measurement of the extension of the specimen during tensile, compression, and flexure tests
  • One camera per test axis
  • Quick test setup
  • No influence on the specimen and the test temperature
  • Mounting of sensor arms is not necessary
  • Flexible measurement lengths and measurement ranges
  • Easy access due to mounting outside of the chamber
  • Application options span the entire temperature range of the temperature chamber

With the Kappa Multistation DTR VMS improves driving comfort in prototype cars and models in development

In the automotive industry vibration dampers serve to eliminate undesirable resonances from the vehicle frame so that these do not get passed from the engine to the driver compartment. These vibration dampers mainly consist of rubber and ensure constant damping characteristics across a wide temperature range. DTR VMS is a manufacturer of rubber-to-metal components for production into engine mounts, transmission mounts, chassis/suspension mounts, torque arms, combustion engines and electric vehicles.
