Importance of placing specimen accurately on dart impact tester

Plastic film is a ubiquitous material in today's packaging industry. These films are lightweight, and versatile, making them an ideal choice for a wide range of packaging applications. These films can be used to wrap delicate items, line boxes, or create bags and pouches. It is also frequently used as a barrier material to protect products from moisture, dust, and other contaminants. Thus, testing the dart of these films is of utmost importance to make sure that your package will withstand free-falling darts. Presto has come up with one of the amazing lab testing instruments known as a dart impact tester which is helpful in measuring the strength of plastic films to withstand the falling dart. The prima model of this testing equipment will come with an electromagnetic dart hold/release mechanism to avoid any type of interference in force exertion. 

Every time you use a Presto dart impact tester, it is critical that the specimen should be placed correctly. This testing instrument uses a falling weight to generate the force for the impact, and if the specimen is not positioned correctly, then the results of the test will be inaccurate. With proper care and attention to detail, you can ensure that your dart impact tests are conducted accurately and produce reliable results.
Let’s discuss brief information on the importance of placing the specimen accurately on the dart impact tester. But before that, let us discuss the importance of dart impact tester in the packaging industry. So, let us get started!

Accurately evaluate the impact of the free-falling dart on plastic films with the Presto dart impact tester 

Plastic film is a versatile material with a wide range of applications. It is strong and lightweight, making it ideal for packaging and shipping products. Plastic film can also be used for labels and other purposes. Its durability means that it can withstand the rigors of shipping and handling.
This material is also easy to print on, making it ideal for branding and marketing purposes. In addition, plastic film is recyclable, making it a sustainable choice for packaging and other applications. Therefore, manufacturers can easily rely on this testing instrument to make sure that the right products will be delivered to the customers with ease. We at Presto is a leading manufacturer of dart impact tester testing instrument and provide you with high-tech lab testing instruments to accurately deliver products to the customers.
The major force that a plastic film can bear will be the force of a free-falling dart. This free-falling dart will directly impact this plastic film material and damage the material wholly. Thus, by testing your product with a Presto dart impact tester, you can accurately evaluate the testing strength of these plastic films.
Below we have listed the features and technical specifications of this testing equipment.

Role of placing specimen accurately while conducting a dart impact test

It is crucial that the specimen is placed on the inner clamping ring while performing a test, as otherwise, the results would not be accurate. Therefore, it is essential that you always place the specimen in the inner ring and put back the outer clamping ring in its place. After placing the specimen, insert the pipe from the vacuum pump into the vacuum pressure ports and plug the vacuum pump into a 3 pin 5 amp socket.
Whenever you place the specimen, then you should make sure that there should not be any form of wrinkles on the specimen. Adjust the height of the dart to make sure that accurate results will take place. In this way, you can accurately place the specimen while conducting the test. You can easily read brief information on the technical adjustments needed to perform the dart impact test.
