What is the use of dart impact tester in the packaging industry?
In the packaging industry, one needs to take care of several factors like product strength, durability, and worthiness against freely falling darts. The packaging products like plastic films, laminates, and composite sheets will be tested against different forces to test their durability. Thus, to make sure that your plastic films will withstand these freely falling darts, you can easily make use of a lab testing instrument known as a dart impact tester. This is one of the amazing lab testing equipment that is used to test the energy of freely falling darts that cause the film to fail under specified test conditions. The dart will be hemispherical in shape and can be held strongly with the dart holder. Here in this article, we are going to provide you with information about the use of dart impact testing instruments in the packaging industry. Let’s start with the brief information about the dart impact tester!

Introduction about dart impact tester

Plastic films and laminates are widely used in the packaging industry, as they provide safety over conventional materials like food packaging and much more. These films are made up of several layers which will in turn helpful in protecting the contents of the materials with ease. Thus, testing these materials against freely falling darts is important to ensure their quality. Therefore, we at Presto have designed one of the amazing lab testing instruments known as the dart impact tester manual and dart impact tester prima model that is helpful in measuring the strength of plastic films of the material to withstand various forces levied on it.
 
It works on an electromagnetic dart holding mechanism that makes it easy for you to conduct the dart impact test on the materials. This instrument will be used to avoid any type of interference in the materials in force exertion. This electromagnetic mechanism present in this lab testing instrument can easily hold a weight of around 2kgs.
 
In the HMI model of this lab testing equipment, you will be able to get an HMI display that will help you to determine the exact number of falls performed in a single test. This quality lab testing instrument will easily determine the impact of the package when it comes in contact with the free-falling dart. Now, let us focus on the working of the dart impact testing instrument.
 

How does the dart impact tester work?

The dart impact test performed on the plastic films will help you to determine the impact of freely falling darts. With the use of this lab testing instrument, one can easily determine the quality of packaging films and ensure zero rejections.
 
If you want to perform the dart impact test on the materials, then you can easily follow the steps mentioned below.
 
  • You can start by operating this machine by plugging it into the main socket of the machine in 3 pins 15 amp socket.
  • Once you start the machine, then you can easily place the specimen accurately. It is important for you to make sure that the specimen will be placed accurately on this testing machine so that one can get accurate testing results.
  • When you place the specimen accurately, then you need to set the height of the dart. You need to adjust the height of the release mechanism according to the test requirement.
  • For testing fix the electro-magnet rod at different lengths of 660 mm & 1524 mm with the formula below:
  • -Required length + Dart length + electro magnet length= Scale Reading
  • Once you set the height of the testing specimen, then you can easily commence the test.
In this way, this lab testing instrument will work. You can even calculate the result of impact failure on the materials with the help of this lab testing instrument.
 
Now, let us focus on the features and technical specifications of the Presto dart impact tester manual model.

Benefits and Uses of the Dart Impact Tester in the packaging industry

In the plastic film industry, plastic films will serve to be the protective barrier between external and internal contaminants. But what if, these films will get a break? It will cause product damage. Thus, it is important for you to test these films against freely falling darts. Therefore, with the use of the Presto dart impact tester, we will be able to determine the quality of these films and make sure that the right materials will be delivered to the customers with ease.

The Presto dart impact testing instrument has been made in accordance with industry standards that include IS 2508: 1984(R2003) and ASTM D1709-16A and various industrial test standards. This will help you to get accurate test results.
 
With its easy-to-use mechanism, you can easily conduct the dart impact test on the materials and make sure that your products will withstand the damage that occurred due to shipping. You can easily conduct a quick and precise dart impact test on the materials.
 
One of the most common uses for the dart impact tester is to verify that products meet specifications. The tester can measure the force required to cause an impact and determine whether or not the product meets the required strength specs. This information can be used to create packaging that is safe for shipping and storage.
 
Conclusion

Another benefit of using a dart impact tester is estimating potential damage during shipping and storage. By measuring the force needed to cause an impact, it is possible to estimate how much damage a product may sustain during transportation or storage. This information can help to minimize the risk of product failure. The dart impact tester can also be used to detect possible quality defects. By measuring how much force is needed to cause an impact, it is possible to determine if there are any inconsistencies with the product's material composition. This information can help to prevent potential issues with quality control during manufacturing. You can read more about the usage of dart impact tester in the packaging industry.
