A universal testing machine, also known as a tensile-compression testing machine, is can perform a wide range of static tests, such as tensile and compression, bending, peel and adhesion, and other mechanical tests. It allows standardized tests to be performed on a wide variety of materials and numerous applications in more than 20 industries. A common universal materials testing machine includes a load cell, a crossbeam, an extensometer, grips and electronics.

It is controlled through testing software which is used to configure and predetermine the machine and security settings and save the test parameters, such as ASTM and ISO, among others. Through the force applied to the specimen, the compression rupture properties (in the compression direction) or the deformation properties (in the tensile direction) of the specimen are determined throughout the entire test. The measurement of the compressive strength or the tensile strength of materials helps builders and fabricators predict how materials will behave during their intended use.

How does a universal testing machine work?

The universal testing machine is generally modular in design, allowing the user to change the direction of compression (pressure) to the tensile (tension) direction and perform tests flexibly with different forces and testing speeds. In addition, the universal testing machines offer a testing system that is individually tailored to each application.

Tensile test

For a common tensile test, the universal testing machine is set up with the grips to suit the test material. The correct test parameters are set (force, speed, measuring length, etc.), and the specimen is clamped by both ends with suitable clamps and pulled until it breaks. 

Compression test

Common measurements for compression test include yield strength, proportionality limit, yield strength, and compressive strength.

Bending test

However, the utm machine can also be reconfigured and converted for bending testing.

A bending test is a compression test in which the specimen is placed on two supports and loaded through the centre with a punch or test point.

One more thing: the machine manufacturer is important

An expensive investment is purchasing a universal testing machine manufacturer. It is crucial that you purchase from a reputed manufacturer as a result. When looking for a machine, make sure the manufacturer promises the following qualities:

Accurate and repeatable results

The integrity of the machine frame must exceed requirements, and the computerized universal testing machine design and construction must be top-notch to ensure continuous, repeatable results over years of use.

Safety of technicians and machines

The safety of laboratory technicians and service personnel is paramount. Machines must be designed with the operator in mind, regardless of skill level.

Easy to use

The ergonomic design and elaborate details should ensure easy testing, even for new technicians.

Customer Service

You'll know you have a good machine if it's built and supported by an expert technical support team that knows the industry well. If you want your machine to last, work with a manufacturer that offers a dedicated group of engineers and technicians who have years of experience with your equipment. This way, you can be confident that any issues that arise will be resolved in a timely and appropriate manner.
