Test Automation

The number of required tests has climbed steadily in the last few years and the run time for the individual tests must be reduced. Automation reduces also the statistical spread of the test results.

These are the reasons why many testing laboratories are already equipped with automated Zwick testing machines.

Operator influence on the test results is minimized because all the specimens are tested exactly alike. Test results can be better compared with one another and are statistically more reliable.

There are many other good reasons for testing automation. Here are a few examples:

• Laboratory personnel are relieved from simple routine tasks and can dedicate themselves to more challenging laboratory duties.

• Zwick handling systems can test complete specimen charges overnight as well and do not require supervision.

• The amortization of these handling systems is usually less than two years, dependent on the specimen quantity.

• Logbook functions allow the exact auditability of the testing conditions for every single test.

• Different test types such as tensile, roughness, and hardness can be combined in a single system.

• The test results can be transferred directly to a higher-level computer system.

Zwick has developed a modular system for automated testing to allow the required tests to be performed efficiently and reproducibly. Customer-specific solutions can be individually configured from the standardized components.

Some examples:

miniHasy For fully automatic tensile testing of metal specimens (e.g. to ISO 6892, EN 10002-1), coupled directly to the load frame.

X-Linear System with expanded specimen magazine and integrated cross-section measurement for tensile and bending tests.

Polar Universal system for tensile and/or bending tests, roughness tests, and hardness tests as well as for multiple sorting specimen disposal with industrial robot.

Portal Universal system for tensile and/or bending tests, roughness tests, and hardness tests as well as for multiple sorting specimen disposal with linear axes.
