Plastics have a variety of characteristics and attributes that define their quality, such as molecular elasticity. It is used to determine a polymer's impact strength. This property is critical in determining the product's stiffness, which explains the plastic's ability to endure the force applied to its surface. Thus, you can easily calculate the dart impact strength of the materials with the help of the Testronix dart impact strength tester. This is one of the effective testing instruments that are widely used instrument in different packaging industries where it is used for testing the strength of the plastic films and is best for testing the ability of the film to withstand the various forces levied on it.
This impact testing equipment, which can be used for dart impact testing, confirms that under particular conditions the force of the falling dart truly ruptures the plastic film. This determines whether the film or plastic layer underneath needs to be tougher or not. Plastic film manufacturers frequently make sure that their product is sturdy enough to endure the effect of any external forces.
Here in this blog, we will discuss brief information about dart impact tester and how this lab testing equipment is useful in testing the impact strength of plastic films.
Plastic films are widely employed in a variety of sectors for a variety of applications. The packaging sector is the largest user of these plastic films. Shrinkwrap, bubble wrap, and other packaging materials are made with these films.
When plastic films are used to package things, it is critical that the films be robust enough to protect the products inside. Freely falling weights are one of the most powerful and significant pressures that a plastic sheet must withstand. The freely dropping weight might seriously harm the plastic sheets and, as a result, destroy the entire product container. One of the most common ways for determining the strength of films is to make use of a dart impact tester for plastic films.
An electromagnetic area with a dart hold and release mechanism are included in the test equipment. The circular clamp with the shielding structure shown below is used to prevent the dart from slipping out after bouncing on the sample. As a programmed controller, there is a paddle switch for convenient operation and an HMI-based Touchscreen display.
Below we have listed the features and technical specifications of the impact tester for films.
This impact tester for plastic films is used to assess the quality of packing films by calculating their resistance to free-falling weight during storage and transportation. It satisfies test requirements like IS 2508:1984(R2003), ASTM D1709-16A. Read out the features we are providing in our dart impact testing instrument.
With these features and technical specifications, you can easily conduct the dart impact test. Now, let us discuss how this lab testing equipment will be operated easily.
To measure the effect of a free-falling dart on plastic films and laminates, a dart impact test is done. Under some situations, the energy released by the falling dart causes the film to break down.
The user must turn on the Dart Impact Tester and insert the specimen in the clamping area to begin the test. Impact tester parameters like test method, dart weight, number of samples, magnet hold time, failure percentage, username, etc. can be set.
After that, the sample may be clamped and the test can be started automatically using the paddle switch. The user can pick from a number of Darts and place them on the electromagnetic platform (as per the test standard technique). The dart is free to fall on the plastic film fastened beneath it. The final product is examined visually. In this way, you can easily conduct the dart impact test with the help of this lab testing instrument.
