With the rapid advancement of science and technology, the testing machine industry has also experienced significant growth. Earlier models, such as those with manual disc readings, cumbersome operations, and poor performance in material testing, have now been largely replaced. Today, hydraulic universal testing machines have become more common in the market. These machines are a direct result of technological progress and are widely used to evaluate the tensile, compressive, and bending properties of various materials, including metals like steel and copper, as well as non-metallic substances such as castings, cement, and concrete.
The process of conducting a tensile test on metal materials using a hydraulic universal testing machine involves several key steps:
(1) Choose an appropriate tensile fixture and install it properly.
(2) Power up the system in the correct order: display, printer, computer, industrial computer, launch the testing software, and activate the hydraulic source.
(3) Enter the testing interface, select the desired test method, set the parameters, measure the sample dimensions, and input all necessary information.
(4) Securely mount the tensile specimen onto the testing machine.
(5) Attach an extensometer to accurately measure material deformation during the test.
(6) Reset the sensor reading, switch the control to the load mode, open the hydraulic valve, and click the "Run" button to start the test.
(7) The machine will automatically save the data once the specimen breaks and then close the oil valve.
(8) Remove the broken specimen and open the return valve to release pressure.
(9) Shut down the system in the reverse order: first turn off the hydraulic source, exit the testing software, shut down the industrial computer, then the computer, display, and finally the printer.
As shown in the above procedure, the hydraulic universal testing machine offers a simple, efficient, and highly automated way to evaluate material properties. Its advanced measurement system can automatically collect and process data, eliminating the need for manual data entry and reducing the risk of human error. This leads to more accurate and reliable results. Because of these advantages, the hydraulic universal testing machine is highly preferred by professionals and is widely used in industries such as metallurgy, machinery manufacturing, power infrastructure, boiler production, academic research, and quality inspection centers. It has become an essential tool in many laboratories around the world.
