From Metals to Polymers: The Versatility of a UTM.

The term "universal" refers to the machine's ability to perform a wide variety of different mechanical tests on a single frame. A universal testing machine is not limited to just one type of test; it can be configured for tension, compression, bending, shearing, peeling, and other tests, making it a "universal" tool for mechanical material characterization.

The three primary tests performed by a universal testing machine are: Tensile testing, which pulls a sample apart to measure its strength and ductility; Compression testing, which squeezes a sample to determine its behavior under load; and Flexural testing, also known as a bend test, which measures a material's stiffness and bending strength.

To choose the right force capacity, you must know the maximum expected strength of the materials you will test. It is crucial to select a universal testing machine with a maximum force capacity that is comfortably above your strongest sample's breaking point. This ensures the machine is not overloaded and that the load cell operates in its most accurate range. WBE offers a wide range of capacities, from low-force tabletop models to high-force floor models.

Grips and fixtures are the components of a universal testing machine that hold the test specimen in place. Grips are typically used for tensile testing to clamp onto the ends of a sample. Fixtures, such as compression platens or bend fixtures, are used for compression and flexural tests. The proper selection of grips and fixtures is critical for achieving accurate test results.

The main difference is the design of the load frame. A single-column universal testing machine has one vertical column and is typically used for lower-force applications, such as testing plastics, textiles, or medical devices. A dual-column machine has two vertical columns, providing a more rigid frame that is necessary for higher-force testing of materials like metals and composites.

A WBE universal testing machine is a smart investment because it combines precision, durability, and versatility. Our machines are built with high-stiffness frames and high-accuracy sensors, as proven by clients who achieved 0.01mm precision. This leads to tangible results, such as the 35% reduction in reject rates reported by Guangzhou Auto Parts. With WBE, you are investing in reliable data and a quantifiable return on investment.
