With its Cobb Tester, Test Your Product determines water absorption by papers and packaging materials and their resistance to water penetration. This is where you will then be able to improve your process parameters, choose suitable materials, and foremost, maintain your product quality and integrity. The paper and packaging testing equipment replicates real-world conditions and thus provides vital projections about material performance and service life. Organizations involved with water-resistant packaging depend on Cobb Tester for quality assurance purposes and the Cobb Tester price is available on the website of Test Your Product.
Cobb Tester working:
For a test, we first prepare a test specimen from the material to be assessed. The test samples can be papers, boards, or any other packaging materials. Clean, dry, and attach the sample to the machine according to the Cobb Test method.
A cylindrical test weight is attached to the setup of the tester. The equipment imitates the water absorption that the material would have in the real environment.
Specific tests require appropriately set test conditions like test duration and water volume. The test can be initiated once all preparations are set up. Water absorption is measured by the strong Cobb Tester during the testing phase of the material. Various test conditions can be mimicked by manipulating the parameters of test duration and water volume.
After the completion of the test, the materials are evaluated to find out their water absorption characteristics. Evaluating those materials could be helpfully aided by some systems like analytical balances and thickness gauges.
The Cobb Sizing Tester is a useful piece of testing equipment for maintaining material quality standards. The Cobb test method allows for anticipating potential problems and will guide users in selecting materials that will streamline their product designs.
