How to Prepare a Sample for Co-Efficient Of Friction Tester?

If you are looking for one of the effective testing instruments that will help you to determine the stackability of plastic films, then we suggest you go with Presto co-efficient of friction tester. This is one of the amazing testing equipment that will help you indicate the sliding friction of plastic films and sheets when sliding over itself or other substances. In the plastic industry, the desire of every manufacturer is to avoid any friction between their packaging products so as to avoid any damage.

For instance, if two packets are slippery in nature then they will slip down from the storage space and may even fall or burst. Thus, you need to keep a check on the sliding friction of your packaging materials in order to keep them away from getting damaged. Here in this blog, we are going to provide you with information about how you can prepare specimens accurately in your testing machine. But first, we will discuss the main purpose of using co-efficient of friction tester- Digital model.

What is the main purpose of using co-efficient of friction tester- Digital model?

In the flexible packaging industry, the manufacturers focused more on evaluating the quality of products and checking the friction in them. The products having more slipperiness in the package tend to get damaged during storage and transportation. Thus, it is very necessary for you to check the stacking friction of flexible packages so as to invest in quality.  

The coefficient of friction, or COF, is determined by the ease with which two surfaces slide against each other. The dimensionless value of the coefficient of friction is the ratio of the force required to slide the surfaces to the force perpendicular to the surfaces. When the product has lower friction, then it will indicate that the surfaces are slicker that means there is less resistance to the sliding motion.

Therefore with the help of the coefficient of friction tester digital model, you can easily evaluate the friction in plastic films. This testing will be performed by sliding the plane beneath a block or weight. The film specimen will get attached to the base of the block and then the block will get connected to the load cell which measures the frictional force between the plane and the block.

Now, let us focus on the features and technical specifications of this lab testing instrument.
