The STM series test device is designed for easy and accurate testing of low cost materials. Advanced technology and high quality engineering enables the user to test the high speed and reliability of the material. Various extensions (high resolution courses or short-resolution courses) are connected to the device to measure very precise strain. The wide range of crossshead speeds allows the operator to test the materials according to international standards ASTM, DIN, ISO, and so on. STM devices are designed to test a wide range of materials. The STM Controller is able to control the device and show the values ​​of measuring tools. All test procedures such as sample input parameters, test methods, test reports, motion control, and demonstration of measurement tools are all by software

High temperature extensometer

Application: Hot creep and tensile test for metal materials with high E to obtain the exact length change value from the test sample

In almost all tensile testing machines in the world, the change in sample length is normally measured from the displacement of the jaws, and errors due to slipping of the jaw wedges, deformation and stiffness of the device, and non-uniform cross-section of the sample make errors in measuring the actual change in sample length. Finally, it creates the percentage of elongation and the modulus of elasticity. To eliminate this shortcoming, an extensometer is used. Changes in sample length, type of grip, accuracy and sensitivity, type of suitable extensometer are selected. The EHR-12H allows accurate measurement of sample length change in hot creep and tensile tests.


Application: Force measurement for universal tensile and compression testing devices

Load cell is usually used in test devices for measuring the force and according to the standards of ISO 7500, EN 10002.2, DIN 51221, ASTM E-4 class and the accuracy of measuring the force for the tests has been determined. By covering the above standards and with an accuracy of 0.5% of the reading value (% Reading) from 2% to 100% of the nominal capacity in the tensile and compressive state, the LS-150 allows accurate power measurement.

Thermal chamber

Application: Tensile test of all types of samples at high temperature

The hot compression jaw, which is made of superalloy, is closed on the fixtures and placed inside the furnace for hot testing. To prevent heat transfer from the fixtures to the load cell and the device, hydrogen peroxide has been used in the fixtures

Automatic pneumatic jaw with a capacity of 25 tons

Application: Tensile jaws for metals and materials with high modulus of elasticity

During the traction test, the lateral force of the jaw must be increased to prevent the specimen from slipping or abruptly releasing. The automatic jaw provides this lateral force in proportion to the increase in tensile load. The PWG-250 automatic jaw function is pneumatic. One of the most important advantages of the PWG-250 is the increase of a constant force by pneumatic pressure to the lateral clamping force due to the effect of the automatic jaw wedge during the test. This feature prevents the sample from slipping during the test

Torsion test fixture for hose interface pipe

Application: A special fixture is required to determine the torsional resistance of the hose connection to the hose head. The FT-T405 allows this test to be performed on a traction device.

Jaw test bolts

Application: Testing bolts with a capacity of 25 tons

The bolt and nut test jaw has two main bodies that are mounted on the machine or on a stretching jaw and are self-aligning and are in two types: Symmetric and Asymmetrical, and a pair of discs is used for each screw size. In the asymmetrical type, the discs are screwed to the body and in the asymmetric type, the discs are placed inside the jaw through a U-shaped slit

Jaw pressure

Application: Ring Stiffness test of plastic pipes

The CF600-250 consists of two fixed plates for compression testing that are mounted on the hydraulic jaws of the machine

Rotational fatigue test

Application: Fatigue test

Various materials, especially metals under repeated or oscillating stresses, break at stresses far less than the stresses required for failure due to the application of a single load. Many engineering components have to withstand multiple cycles of force or stress throughout their service life. SFT rotary fatigue testers make it possible to perform fatigue tests on different specimens in accordance with different standards and instructions for applying reverse flexural stress

SFT-600A fatigue test machine in power, energy, road and construction, aerospace, medicine, etc. to measure the service life of parts and equipment such as turbine blades and other power distribution equipment, pressure vessels, pipes, fins, compressors, Small and large metal and non-metal parts, including steel, aluminum, etc., parts and accessories related to civil engineering such as beams, metal and polymer background composites, welded equipment, packages and fittings used in the aerospace industry, plastics and simple rubbers Also enhanced, biomedical materials such as orthopedic materials, dental implants, spinal implants are used
