Challenges and Common Issues in Compression Testing Machines

Compression testing devices are used to investigate material behavior under continually increasing compressive force. Compression tests are used to assess the safety, durability, and structural integrity of materials and components. Compression tests on plastic tubes and pipes, compression tests on flexible cellular foam material, compression/crush tests on paper and cardboard, compression spring testing in the metals industry, compression tests in the medical/pharmaceutical field, including compression testing of medical implants, stents, syringes, or medical packaging, compression and notched compression tests on composites are examples of typical applications.

compression testing machine is a universal testing machine (UTM) outfitted with compression test equipment or compression platens for specialized applications. The tools are chosen and placed in the machine depending on parameters such as the test type, specimen material, and size, test temperature, and predicted maximum force values.

What Exactly Is Compression Testing?

What is Compression Testing

The compressive strength test, which is often performed in the monoaxial regime, checks the resistance of materials to stresses that tend to deform and shorten their extension or compress them. This international standard governs its usage mostly on concrete.

CTM Machine is a type of universal testing machine (UTM) that is particularly designed to measure the strength and deformation behavior of a material under compressive (pressing) pressure. A compression tester is typically made up of a load cell, crosshead(s), compression test equipment, electronics, and a driving system.

Testing software is used to specify machine and safety settings as well as save test parameters required by testing standards such as ASTM and ISO. It is essential to consider the material to be tested as well as the standard(s) that must be followed when selecting compression test equipment. Measuring the force until a specific load or distance is attained or until the specimen fractures or breaks assists designers and manufacturers in predicting how a material will perform when used for its intended purpose.

Compression Testing Machine Common Issues and Troubleshooting Techniques

The major purposes of a compressive testing machine are compressive strength testing, stacking strength testing, and pressure compliance testing. The instrument uses imported servo motors and drivers, huge LCD touch display panels, high-precision sensors, single-chip microcomputers, printers, and other innovative components from both China and the United States.

It has the advantages of easy speed adjustment, simple operation, high measurement precision, steady performance, and comprehensive functionality. This instrument is a large-scale mechatronics test system that must be extremely reliable. The design incorporates numerous protective measures (software and hardware) to increase the system’s reliability and safety.

The failure of the compression testing machine is frequently visible on the computer display panel, although it is not always the result of software or computer failure. You should thoroughly examine it, paying close attention to every aspect, and provide as much information as possible for the final troubleshooting. Please continue in the following sequence for troubleshooting methods:

Computer Hardware and Software Issues: The program frequently fails because the computer hardware is defective. Please repair the computer in accordance with the manufacturer’s specifications. In the event of a software problem, contact the manufacturer. Is this anything that happens during file operations? There is an issue with the extracted file and an error in the file procedure. Refer to the file operation instructions in each chapter for more information.

The display of the zero point of the test force is chaotic: examine whether the ground wire (sometimes not) added by the manufacturer during debugging is trustworthy. There is a significant shift in the environment; the CTM machines should operate in an environment free of evident electromagnetic interference. There are further requirements for the temperature and humidity of the environment; please see the host handbook for more information.

The test force only displays the maximum value: When the test force displays only the maximum value, consider checking the calibration button and connections. Check to see if the AD card configuration in “Options” has been modified. If the amplifier is damaged, contact the manufacturer.

The saved file cannot be found: By default, the program uses a fixed file extension, regardless of whether another extension is specified during storage. Additionally, ensure that the saved directory has not been modified.

Printer Troubles: In cases where the printer refuses to print, consult the printer handbook to verify the correct operation. Ensure that the correct printer is selected in the software settings.

Other Issues: For any issues not covered here, it’s advisable to contact the manufacturer promptly and maintain a record of the problem for reference.
