Guide on Selecting the Right Compression Testing Machine

compression testing equipment 

A compression test is a strategy utilized to determine the compressive power or how resistant it is to smash along with the object’s capacity to recuperate after the application of a predetermined compressive power. These pressure tests are utilized to establish the behavior of an object under a load. Compression testing machines are used for this purpose to determine the resistance of the substance. Various characteristics are determined during this procedure, like maximum load, stiffness, load at rupture, stress, offset yield, deflection at rupture, and much more.  

Merits of Compression testing

  • To establish the quality of the material.
  • To decrease the cost of the material.
  • To attain manufacturing objectives.
  • To conform to international and industry guidelines.
  • To ensure the strength of the material and its endurance to pressure.

Compression testing is used in the following industries-

  • Construction industry
  • Automotive and aerospace industry
  • Safety industry
  • Health and fitness industry
  • Electronics industry
  • Packaging industry
  • Cosmetics industry
  • Medical industry

Let’s discuss some tips on how to buy a compression tester.

  1. Determine the type of matter

There are different types of material that can be tested. Determine the type of material you want to test. It could be ceramic metal, metallic foam, polymers, composite metal, and many more. The type of material will determine the type of machine that is required for compression testing. 

  1. Size and shape of matter

The material to be tested can vary in shapes like rectangle, square, cubes, prisms, cylinder, and much more. Even the size of specimens can vary from small to medium to large. The testing machine should be such that it can fit the largest size specimen and any shape that you want to test. Additional accessories are also available to fit different shapes.

  1. Safety features

Ensure that the testing machine is equipped with security measures. If you test material with high strength and apply too much pressure on it, the substance can explode. Therefore, there be some safety features like protective barriers to avoid the material to fly away from the machine in case it explodes. Some machines are even equipped with the feature of tensile testing wherein the material is pulled apart to check its tensile strength. 

  1. Test data

Determine the test data so that the software could be selected accordingly. If the number of tests to be conducted is less, then basic software could work. In case you want to collect detailed test data, upgraded testing software will be required.

  1. Comply with international guidelines

Ensure that the compression machine abides by the international and industry guidelines. It should be highly rigid, emit little or no sound, able to perform many tests in a session accurately, use quality oil, and have the appropriate power level according to the material to be tested. The guidelines followed most commonly are ASTM and ISO. The testing equipment should comply with these standards. The machine should be repaired and maintained regularly so that it functions properly.

There are large varieties of compression testing equipment available in the market. Keep in mind the above recommendations to choose the right machine which complies with safety standards and can fit the type of material you want to test.
