Robotic testing systems: a powerful plastics-testing duo

Plastics laboratory staff spend a considerable proportion of their time conducting tensile, flexure and impact tests, together with other mechanical standard tests used to determine material characteristic values. For these routine, everyday tests Zwick can offer an easy route into automation: the roboTest H robotic testing system for impact testing and roboTest B for tensile or flexure tests.

Both systems feature compact design and can be connected to existing Zwick equipment. They are cost-effective, highly flexible and easy to operate - simply place the specimens in the magazine and the fully automatic test can begin. The testing machine can still be used for manual tests whenever required.

Brief description of the two systems
The roboTest B robotic testing system allows a wide range of plastics to be tested efficiently and with maximum accuracy. The magazine holds up to 20 specimens, which are tested fully automatically in quick succession (tensile or flexure tests) and the relevant stress and strain characteristic values, including Young’s modulus, determined.

The roboTest H system is designed for impact tests on notched or un-notched Charpy or Izod specimens. Magazine capacity is also twenty specimens, with optional tempering.

Zwick’s Product Manager Robert Kaifler explains how robotic testing systems deliver precise results: “Eliminating operator influence delivers highly reproducible test results. The entire test sequence is reported via the software and the test results are transferred to a database automatically and free from error.  Qualified laboratory staff are consequently relieved of routine activities and are available for more complex tasks.“

Zwick is world leader in the development of robotic testing systems, with more than 350 system installations worldwide over the last 25 years serving a broad range of industries.
