How to Perform a Dart Impact Test on Plastic Films: A Step-by-Step Guide

A dart impact test is a method to measure the impact resistance of plastic films and laminates by dropping a dart on them from a certain height. The test can help evaluate the quality, durability, and performance of various plastic products and materials. The test can also help compare the effectiveness of different surface treatments, such as electroplating, galvanizing, painting, etc. The test is standardized by several national and international standards, such as ASTM B117, ISO 9227, JIS Z 2371, and ASTM G85.

To perform a dart impact test on plastic films, you will need a dart impact tester, a sample holder, a scale, a release mechanism, and a sample of the material to be tested. You can find some examples of dart impact tester online, such as Presto Group or Amazon. You can also compare the prices, features, and specifications of different models and brands and choose the one that suits your needs and budget.

Here are some steps that you can follow to perform a dart impact test on plastic films:

1. Prepare the sample of the material to be tested according to the standards and specifications. The sample should be large enough to extend beyond the sample holder by at least 25 mm at all points. The sample should also be representative of the material under study and should be taken from the sheet or tube in such a manner that the whole of the sheet is represented in the test. You can use a template to guide the cutting of the sample and a thickness gauge to measure the thickness of the sample.

2. Clamp the sample in the sample holder and connect the pneumatic pipe to the vacuum pump. Turn on the vacuum pump to hold the sample securely and prevent any air pockets. The sample should be clamped by the specimen holder ring and should have a slit that allows the dart to pass through and tear the sample.

3. Adjust the level of the machine with the spirit level and lock the leveling bolts in the proper position. Ensure that the apparatus does not vibrate and has a proper earthing connection. Connect the power supply cord of the device to a 3-pin 5-ampere socket on a single-phase 230 V AC supply line.

4. Choose the appropriate weight of the dart that is nearest to the expected impact failure weight. You can also add the required number of incremental weights to the dart shaft and put the locking collar in its place to set the weights in a particular location.

5. Adjust the height of the drop of the dart according to the standards and application requirements. You can use the release mechanism of the vertical channel support to set the height of the drop. The dropping height of the dart can be 660 mm or 1524 mm, depending on the type of test.

6. Place the dart in the release mechanism and align it with the center of the sample. Make sure that the dart is free from any dirt or dust and has a smooth surface.

7. Release the dart from the starting position by using the trigger or the button of the release mechanism. The dart will fall freely and hit the sample, causing it to tear. The force and the distance of the tear will be recorded by the scale and the display of the device.

8. Remove the sample from the sample holder and examine the damage caused by the dart. You can use a marker to record the maximum force reached by the pointer and the scale. You can also use a ruler to measure the length of the tear.

9. Calculate the Falling dart impact tester of the material by using the formula: Dart impact strength = Weight of the dart in grams / 10 min. You can also use a computer interface or software to generate graphical and numerical reports of the test results.

10. Repeat the test with different samples and weights of the dart to obtain an average value of the dart impact strength of the material.

I hope this guide helps you to perform a dart impact test on plastic films.

What Is a Dart Impact Tester? Its Applications & Working Module!

Advanced Technical Features in Dart Impact Tester by Presto

A Dart Impact tester or Dart Drop Tester is a lab testing instrument that is used to measure the Impact Resistance of Plastic film, Coated paper, and Composite sheets. The dart weight expresses the energy required to tear or puncture the test specimen. This method is also known as the Free Falling Dart Impact test.

Here, Presto Stantest presents Drop Dart Impact Tester with quality assurance. This testing instrument by Presto helps to determine the energy that causes impact from a free-falling dart on thin materials such as plastic film, paper, etc. To know the competitive Dart Impact Tester price in India, contact us at 9210 903 903 or you can mail us your query at info@prestogroup.com.

How does it work?

In this test procedure, a sample clamp is used for an easy grip and security of the specimen. It helps in ease of operation. In addition, the Dart impact tester provides a dual clamping sequence for better performance. In the first phase, low pressure is utilized to safely clamp the sample. In the next phase, the automatic dart release completes the test process.

The company possesses decades of working experience in testing instruments manufacturing. Hence, it is well aware of the requirements in various testing machines. Therefore, to meet the need for the dart Impact test, the company came up with advanced technical features that are as follows.

Meets Global Standards of ASTM 01709 for Dart Impact Testing of Plastic Film

Test the quality of packaging films using the Presto dart impact tester

Packaging films are a great option for protecting your products so that they reach their destination in pristine condition. These packaging films can also provide a barrier between the product and the environment. It is important for the packaging manufacturers to test the quality of films against freely falling darts in order to deliver accurate products to the customers. Thus, we at Presto are considered being the leading manufacturer of dart impact tester, one of the quality lab testing instrument that is used to test the quality of materials with ease. It widely used this quality lab testing equipment in the packaging and plastic, and polymer industries to test the materials against freely falling darts. Here in this blog, we will discuss a brief about how you can easily test the quality of packaging films with the help of the Presto dart impact tester. But before that, let us discuss the use of plastic films in the packaging industry.

What are packaging films and for what purpose you can use them?

Packaging films are generally used in the packaging industry to protect products from damage during shipping and storage. They also act as a barrier between products and the environment, keeping them safe without getting any damage. It widely used packaging films in the industry like PET, HDPE, PS, PVC, LDPE, and PP. Each has its own unique properties that make it ideal for certain applications. PET films are the most commonly used type of film in the packaging industry. They are durable, lightweight, and have high tear strength. They are also water resistant, which makes them ideal to deliver products accurately to the customers.

Testing the quality of these films against freely falling darts is an important part of the quality control process and ensures manufacturers make sure accurate products are delivered to their customers. The prima model of this high-quality lab testing equipment is based on the electromagnetic hold and release mechanism for the dart to obtain accurate testing results. It comes with a user-friendly HMI-based touchscreen model with a drop height adjustment clamp to make it easy for the users to conduct the dart impact test. Now, let us discuss brief information about the Presto dart impact testing instrument.

Introduction about Presto dart impact tester

We all know plastic films are prone to get damaged under dart impact force applied on the materials. When this dart will be fallen from a certain height, then it will rupture these films. A poor quality packaging film will easily resist these impact forces and is considered being less durable. To ensure that there will be no damage occurring while delivering the materials to the customers, it is important for the packaging manufacturers to conduct the dart impact test on these plastic films. This is where the Presto falling dart impact tester plays a significant role. This high-quality lab testing instrument will easily determine the impact resistance strength of these films against freely falling darts. When the dart will be dropped from a certain height, then its weight will send a certain amount of energy to the tested specimen. Under these conditions, the specimen will easily get ruptured or will fail when dart impact force will be applied to the materials. By using the Presto dart impact tester, one can easily ensure that quality products will be delivered to the customers.
