The Scientific Research Notes Of S. Sunkavally (years: 2002-2011).

Abstract In this review, we discuss the current knowledge on the tribology of human skin and present an analysis of the available experimental results for skin friction coefficients. Starting with an overview on the factors influencing the friction behaviour of skin, we discuss the up-to-date existing experimental data and compare the results for different anatomical skin areas and friction…

Looking for a best quality coefficient of friction tester and you cannot find anywhere such an instrument which is upgraded with the latest model and extra functions? Presto coefficient of friction tester is based on the latest technique and extra features which are easy to use and handle. This is a great tool used in box and packaging industries for testing, which does its job well. We know presto for its unique design and best quality friction coefficient manufacturers in India.

Presto’s Coefficient of Static Friction machine is mostly used to evaluate the coefficient of starting and sliding friction of plastic sheets, papers, films, and pipes. It measures the kinetic and static friction of the test specimen when it slides over substance in a specified test situation.  The test is done to evaluate the stack ability of plastic sheets and films. These test procedures help plastic manufacturers to avoid accidents due to resistance in loading, packaging, and transporting materials. 

In the plastic product manufacturing industry, it is important for manufacturers to conduct co-efficient of friction tests on the materials in order to ensure quality. By understanding the friction properties of plastic films, laminates, and other related materials, one can easily ensure the accuracy of these films. Thus, we at Presto have designed one of the high-quality lab testing equipment known as a coefficient of friction tester that will accurately measure the stackability of these films and sheets so that no damage will occur while shipping or transporting products to the customers. This friction tester for plastic films is highly used to ensure that the materials delivered will be of high quality.

What is the coefficient of friction?

The friction coefficient is considered to be the dimensionless property of the material that helps to determine the surface roughness of the material and measure the changes that occur in the state of motion. This property of the material will help to optimize the packaging process and ensure that the products will be protected from damage during transport.

In addition to that, this property of the packaging material will help to make sure that the products will arrive safely to their destination safely and in precise condition. To make sure that the coefficient of friction value of the products can easily be determined you can easily make use of the Presto co-efficient of friction tester.  

Introduction about Presto COF tester

Presto co-efficient of friction tester is one of the high-quality lab testing equipment that will measure the kinetic and static friction of the test specimen when it slides over a substance in specified conditions. This high-quality lab testing instrument will accurately measure the kinetic and static friction of different materials like plastic sheets, plastic packaging films, laminates, and many more. The users will get highly accurate testing results of sliding friction with the use of this high-quality lab testing instrument. With its feather-touch controls and bright LED display, manufacturers can easily conduct COF tests on the materials. The specimen will be tightened with the fly screws so that there will be no slippage of the testing specimen.

By understanding the co-efficient value of friction, you can easily ensure quality products will be delivered to the customers with ease. You can read about the importance of a coefficient of friction tester in the packaging industry.

How does the coefficient of friction tester work?

In order to ensure that films are performing as expected, it is important to test both static and dynamic friction. Static friction tests measure how much resistance exists when two surfaces are pressed together. Dynamic friction tests involve applying forces over time in order to measure how much movement occurs between two surfaces.

If you wish to conduct a co-efficient of friction test on the materials, you can easily follow the steps mentioned below.

Prepare the testing specimen first, by cutting the sheet according to the size of the glass approximately of size 53 x 15 x 1mm. The sample is placed over the glass sheet.

Tighten the sample across the glass slab with the help of fly screws attached at the corner.

Take the slide block to the extreme left using the toggle switch and 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.

After following these steps, you can accurately commence the test.
