What is a universal test machine?

The universal test machine pulls, compresses, bends or expands the materials until it breaks. These tests determine the quality of the material and also how suitable for specific use. The universal test machine is mainly used by laboratory that produces or forms various plastics.

One or two vertical columns are mounted on the base to form the body of the universal test machine. The second horizontal plate with attachment agents that holds the sample, slips up and down when performing stress tests on the samples. Machines with one vertical column are usually smaller and more affordable, although often lack the ability to squeeze materials. Dual vertical column machines are significantly more expensive, but can handle larger samples in terms of size and weight.

The most common test carried out by the universal test machine is the tensile strength test. One end of the sample is held in place, while the other end is towed until the two sides are torn. BendingIt is tested in a similar way, but the machine pushes to one end of the sample instead of pulling it. The test stops again when the sample breaks, although some materials are flexible enough to bend rather than break, and do not provide any final results.

Shear tests and compression tests are less common, although they are still used for different materials. In a compression test, the sample is pressed between two plates until it breaks or lost its appearance. This test is often used to measure the force of plastic foams and to find out how easy plastic bottles lose their shape. In a shear test, the metal blade is pushed into the sample at a constant speed until it cuts from a piece of sample. This test is measured in terms of cut force/surface.

In the early versions of the universal test machine, a specialized record -formation was used for the test protocolOver a specialist. Current models are managed by digital controls and computer software. These programs are sufficiently sophisticated to perform the test and display the results while the test is still ongoing. The advantage is that engineers can see how stress affects the material up to the point at which it breaks. This information allows engineers to determine how well the material is held under different conditions.
