Why You Should Use a Dart Impact Tester for Packaging Industry?

In the packaging industry, there is a vast use of plastic films that act as a protective barrier between external contaminants and inside content. Thus, it is very important for you to use the right testing instrument to check the quality of these plastic films. Thus, we at Presto have come up with a dart impact tester that is provided with an electromagnetic dart hold/release mechanism to avoid any type of interference in force exertion.

This electromagnetic mechanism can hold a weight of up to 2kg and can be provided with a digital counter in determining the number of falls performed in a single test. Thus, with the help of this lab testing instrument, you can easily conduct a dart impact test. This lab testing instrument will provide you with a digital counter that is helpful in determining the number of falls performed in a single test.

Here in this blog, we are going to provide you with the essential information about dart impact tester and how this lab testing instrument will be helpful in evaluating the resistance strength of plastic film against free-falling darts.

Introduction about Presto dart impact tester 

The Presto dart impact tester is one of the effective testing instruments that will be helpful in evaluating the resistance strength of plastic film against a free-falling dart. When a dart is dropped from a certain height, its weight sends a certain amount of energy to the tightly stretched and clamped specimen. Under the conditions, a low-quality specimen will fail and rupture. Thus, this falling dart impact tester will measure the impact of plastic films to withstand various forces levied on them.

To clamp or unclamp the sample, a footswitch is provided with the machine. The pneumatic clamping provided with the machine is best for providing wrinkle-free clamping of the test specimen. Along with that, there is a shielding device provided with the machine that helps to prevent the dart from bouncing back upon impact out of the machine.

There are many features and technical specifications you will get with the help of this lab testing instrument. You can read about them below.

With these features and technical specifications of dart impact tester, the manufacturers can easily assess the strength and durability of their plastic films and similar other products. Now, let us discuss the role of dart impact tester in the plastic film manufacturing industry.

Role of dart impact tester in the plastic film manufacturing industry

When a dart is dropped from a certain height, its weight sends a certain amount of energy to the tightly stretched and clamped specimen. Under certain conditions, a low-quality specimen will fail and rupture. Thus, it is important for you to make sure that the specimen should be clamped properly in order to get highly accurate test results.

This reliable quality test is very helpful in evaluating the impact resistance of LDPE packaging material. IS 2508:1984(R2003) and ASTM D1709-16A are among the international test standards used in the development of dart impact testing instruments. The device has a hemispherical-shaped head or dart that is held in place by an electromagnetic portion. The magnetic region is in charge of keeping the dart head in place and releasing it. The height of the descent is controlled by shifting the head part upward and downward. An inbuilt digitalized counter is added to keep track of falling cycles within a single test.
