Prevent accidents due to frictions with Presto COF tester
27-8-2022
Plastic films are widely used for coating and wrapping different kinds of packaging materials. With its wide use in different industries, these materials should be tested thoroughly against sliding friction. If the coefficient of friction of these films will be high, then they will easily slide over each other. This can cause accidents while transporting and shipping the products. Thus, we at Presto have come up with a high-quality lab testing instrument known as the coefficient of friction tester. This is one of the premium quality lab testing machines that has been used by packaging product manufacturers to test the sliding friction of materials like plastic films, composites, plastic sheets, laminates, and much more. Here, we are going to provide you with information about how you can easily prevent accidents that occur due to friction with the help of this lab testing equipment.
What is a COF test and why you should conduct it?
A COF test is a type of quality test used to measure the friction between two surfaces. The COF tester is often used to test the friction between the surface of materials like plastic films, laminates, etc., and the substrate on which these materials will be placed.
When the coefficient of friction of these materials will be low then it will signify that low force will be required to move the materials or slide them against each other. A high COF will indicate that much force will be needed for the material to move. This test will be widely conducted in the packaging industries where the use of plastic films, sheets, or laminates will be very high. By taking COF tests on the materials, users can easily ensure the best quality of films delivered to the customers.
To conduct a co-efficient of friction test on the materials, users can easily make use of the Presto co-efficient of friction tester. This is one of the amazing lab testing instruments that will help you to test the quality of materials and the rate at which these materials will slide against each other. You can read more about the COF test and its role in the packaging industry. Now, let us focus on how the Presto COF tester helps to test the frictional properties of the materials.
How to use Presto COF tester?
The Presto COF tester is an essential testing instrument for paper and packaging manufacturers who work to pack the products effectively. The COF tester measures the static and sliding friction of the materials when sliding against each other. The digital model of this lab testing instrument has been made in accordance with industry standards that include ASTM D618, ASTM D 883, BS 2782, and ASTM D 1894 to make it easy for the manufacturers to conduct the co-efficient of friction test.
This lab testing instrument will easily reveal the stackability of plastic films and the degree of the slide they can sustain without damaging the contents.
In order to conduct the COF test on the materials, you can follow the below-mentioned steps.
- To conduct the COF test on the materials, you need to prepare the sample first.
- Once you prepare the sample for a coefficient of friction test, then you need to place it accurately on this lab testing machine.
- You must tighten the sample across the glass slab with the help of fly screws attached to the corner.
- Take the slide block to the extreme left using the toggle switch.
- Now attach the test block to the slide block with the help of a string in such a manner that the load cell must not touch the fly clamp.
Once the specimen will be placed properly, then you can easily commence the test. You can read about the steps to commence the coefficient of friction test. Now, let us discuss the features and technical specifications of this lab testing instrument.
