What is the Importance of Ring Crush Test

When it comes to evaluating the compression strength of the paper, the paper packaging industry conducts a list of significant tests. The crush test is among those tests. Performed using a ring crush tester, the crush test is one of the most conducted tests by paper packaging manufacturers. 

Why it is important to conduct a ring crush test?

A ring crush test is important for the following reasons:

• It determines the strength of the Kraft liner or fluting of the paperboard or corrugated board. Hence, it can correlate with the crucial short-span compression test.
• The test is conducted effectively in both directions, i.e., machine direction and perpendicular direction.  
• The crush test, when performed using a competent ring crush tester, gives high-accuracy results, and within the dedicated time. 
• The compressive resistance helps manufacturers know about the durability and strength of the paper. Hence, if the results are incompetent, the manufacturer can make necessary improvements in the quality and composition of the board beforehand.
• Conducting the crush test also helps manufacturers know if the resulting quality matches the industry standards.

Since corrugated boxes are essential to safely carry products from one place to another, they have to be built using reliable corrugated boards and liners. With the help of UEC’s steadfast crush testers, manufacturers are able to recognize their reliability. Let us look at the equipment’s features below. 

Features of UEC’s Ring Crush Tester

• The ring crush tester is a versatile instrument that performs ring crush, flat crush, and edge crush tests single-handedly. 
• To perform each kind of test, different fixtures come along with the unit, so that they can be properly conducted. In total, there are 8 removable discs for a sample thickness between 0.15 mm to 0.49 mm. 
• Once the test is completed, the results are displayed on a touchscreen microprocessor-based display panel. 
• The clamps in the crush tester are strong enough to clamp the specimen well and prevent them from damage during the test. 
• Besides, the tester also comes with an LED display and inbuilt calibration.
• The tester can also perform compression tests on mono cartons, basically small packages. 
• To print the test results, manufacturers can also opt for a thermal printer and to transfer the test data to the computer, they can opt for software. 
• Samples must be properly cut and prepared using a sample test strip cutter or punch and die cutter.

Conclusion

Ring crush tests are among the most vital tests to determine the compression strength of the paper packaging material. Manufacturers can test both corrugated board and paperboard for compression/crush strength using this tester.
