How Compression Testing is done with a Compression Testing Machine

by Hemant Sharma Digital Marketing Manager

Compression testing is used in order to determine how a product or material reacts on compression, squashing, crushing or flattening by measuring fundamental parameters which determine the specimen behaviour when it is under a compressive load.

More about Compression Testing Machine (CTM)

Compression Testing Machine (CTM) comes in both Analog and Digital type. One can buy it according to the industry need. Today, a user can visit online easily to book order for Compression Testing Machine (CTM) online at a comparatively lower price.

Some of the Compression Testing Machine (CTM) applications are as follows:

Ø   1-It helps to determine batch quality

Ø   2-It helps in determining the consistency in manufacture

Ø   3-It aids the design process

Ø 4-It helps to reduce material costs as well as to achieve lean manufacturing goals

Ø 5-It helps in ensuring compliance with international and industry standards.

Why is the compression test conducted?

A compression test is more commonly done in the construction industry to check the concrete behaviour under the load. It helps to determine the quality of the concrete used in a construction project. Compression tests are generally performed to know the behaviour of a material under the load. The maximum the load a material can sustain, the more is the strength resulting into longer life.

Some of these parameters include the elastic limit which for "Hookean" materials are approximately equal to the proportional limit and also known as yield point or yield strength, Young's Modulus (these, although mostly associated with tensile testing, may have compressive analogues) as well as compressive strength.

Compression testing can be done as part of the design process, in the production environment. It can also be done in the quality control laboratory and can be used to assess the strength of components. E.g. automotive and aeronautical control switches, compression springs, bellows, keypads, package seals, PET containers, PVC / ABS pipes, solenoids, etc.

This test also helps us characterise the compressive properties of materials. E.g. foam, metal, PET and other plastics and rubber as well as to assess the performance of products. E.g. the expression force of a syringe or the load-displacement characteristics of a tennis ball.

Compression testing machines are universal testing machines which are specially configured in order to evaluate static compressive strength characteristics of materials, products, as well as components. Our compression test machines work to measure characteristics like the ultimate compression strength, yield strength, deflection, and also modulus.

Each of the compression testing machines is configured to your test applications. This is done by application engineers who have an appropriate controller, grips, and accessories. Compression testing machines usually have a modular machine design, your compression test machine can thus be equipped to perform other applications like tensile, cyclic, shear, flexure, bend, peel, tear if appropriate fixtures are added.

While choosing a compression testing machine online you first need to determine your specimen geometry, size, and strength characteristics. Once you have the appropriate information, applications engineer will be able to identify the test machine capacity and compression platens which are needed to crush your sample. The next step is to decide the test data you want that will help in confirming the best controller and test software.

Compression testing comes with a number of benefits. It provides data on the integrity and safety of materials, components, and products. This helps the manufacturers ensure that their finished products are fit-for-purpose and that they are manufactured to the best quality. Some of the data produced in a compression test can be used in many ways.

The above are some of the important uses of compression testing. You can buy compression testing machines online at the leading online stores like Bellstone Online and more. The prices are quite reasonable and the products are well worth the cost.
