Significance of top load tester in PET bottle industry

The PET bottle manufacturers need to conduct various tests to ensure that the product they manufacture should be free of errors. One of the most common tests that will help you to ensure the quality of PET bottles is the top load strength test. Thus, to ease this, Presto has come up with one of the most efficient testing equipment known as a top load tester. This testing equipment will help you to test the load-bearing capacity of PET bottles or containers for better quality assurance. Presto offers different models of top-load tester that will help you to determine the accurate and maximum load a PET bottle can bear.

Here in this article, we are going to provide you with brief information about top load testers and why you should use this lab testing equipment in the bottle industry. So, stay connected and read this blog till the end.

What is a top load tester and for what purpose it is used?

Whenever you manufacture a PET bottle, then a certain set of factors including strength, durability, compatibility, etc. should be determined. Thus, with the help of a top-load tester from Presto Testing Instruments, you will be able to test these properties of PET bottles and determine whether they are suitable for delivery or not. One of the highly efficient models of the top-load tester is the Digital Cum Computerized model.

This fully automatic motorized top load tester will give you the value of compressive buckling load in the digital format. It has a high-end sophisticated read-out with Auto-tare (Zero) set facility and peak hold arrangement.

Purpose of top load tester

The main purpose of using a top load tester is to determine the strength of PET bottles and containers. You can easily perform the test on empty bottles or containers at a fixed speed. When downward compressive force will be applied over the bottles, then you can note the measurements of resistance to that force by container or PET bottle. The operation of the instrument is fully automatic and motorized. The digital display offered with the instrument offers an easy reading of the test results with better accuracy. The instrument offered by presto is equipped with efficient concave jaws grips that are designed to provide a better grip on the test samples. Along with that, there is a load cell provided with the instrument for accurate measurement of the force applied to the test sample.
