Electromechanical 1200kN machine tests
steel
In order to meet the growing needs of the steel industry, a range of electromechanical universal testing machines has been extended to 1200kN for tensile, compression, and bend tests.
Zwick has expanded its product portfolio of electromechanical universal testing machines in order to meet the growing needs of the steel industry The maximum capacity has now been doubled from 600kN to 1200kN, and this new machine has been designed to carry out tensile, compression, and bend tests on steel specimens and components

Universal steel testing machines' capacity doubled
For tensile, compression, and bend tests on steel specimens and components, the maximum capacity of electro-mechanical universal testing machines has been doubled to 1200kN.
Universal pendulum impact machine tests plastics
A universal pendulum impact tester for Charpy, Izod, tensile impact and Dynstat tests on plastics offers the highest level of integrity and traceability of results ever seen in such instruments.
The machine has a long crosshead travel compared to the overall height which makes it ideal for gripping specimens of varying length.
The use of precision measuring equipment and state of the art digital electronics means that the machine achieves class 0.5 from 12kN, and class 1 from 2.4kN up to 1200kN according to ISO 7500 in a single range.
There is no need for the user to make any adjustments or select load ranges.
As with all testing machines from Zwick, the most important aspect is the stiff, robust, and stable load frame.
The digitally controlled electromechanical drive and backlash free ball lead screws ensure precise positioning, and speed control.
The standard machine also includes 1200kN capacity hydraulic specimen grips.
The determination of proof stress requires an accurate extensometer, and Zwick's fully automatic digital Macro extensometer easily meets the requirements of the International Standards.
Whilst extremely high position control resolution and accuracy guarantees excellent test results and repeatability, a reliable and maintenance-free AC servo drive, and very low running costs are further advantages for the user.
ISO 6892 is the basis for many international standards for the ambient testing of metals, and defines the procedure for tensile testing.
There are still some differences between the various standards relating to specimen geometry, test speed, and software algorithms for result definition.
However, when a user selects a testXpert intelligent application program to test according to ISO, EN, ASTM or JIS, they can be reassured that the correct test parameters are used.
This makes testing easier and more reliable. Request a free brochure from Zwick Roell ...
