Plastics are widely used in multiple industries for a variety of purposes. With the wide usage, it is important to examine the attributes and characteristics of the plastics to define their quality such as its molecular elasticity.

Molecular elasticity is a very critical property to determine that explains the impact strength, stiffness of the plastic polymers. This also helps to determine how much force a plastic material can bear to its maximum during adverse transportation conditions.

The best way to determine the impact strength of plastic materials is its dart impact strength. If you are looking to buy the best impact tester in the market, we’ve got you covered.

What is the purpose of the Drop Dart Impact Tester?

The testing machine is widely used in different plastic and packaging industries to test the strength of the plastic film. The purpose of performing the dart impact test on the plastic films is to understand whether the film can withstand the various forces applied on it.

Why the need for a falling dart Impact Tester Arises?

Plastic films are used in most of the packaging industries due to its various features such as flexibility and high impact resistance strength. With the wide usage, these films also bear a lot of wear and tear during their use. The most critical situation where the plastic films get ruptures is the vertical fall of load on the plastic film. To ensure that these films are impact resistance, manufacturers need to perform the dart impact test on the plastic films to make sure that the film will avoid crack, bursting against a sudden impact when the product is placed in actual working conditions.

How does the drop dart impact tester work?

The falling dart impact tester evident that under a given conditions how the falling dart will impact the plastic film. The test result helps the manufacturers to decide whether the film of the plastic layer needs to be made more tough. This helps the manufacturers in deciding that the product is sturdy enough to endure the effect of any external forces.

Dart impact tester is one of the traditional standards test methods that helps to evaluate the impact resistance strength of plastic films used for packaging purposes. In this, the sample of a plastic film is clamped on a sample holder platform. Now, a free falling weight is dropped from a certain height and with a certain force.

Using the different test conditions and parameters such as weight of a dart, height of drop, angle of drop is set to create different working conditions and to analyze the impact of the parameters on the sample. This strategy helps to determine the quality of the plastic film.

How to choose the best Drop Dart Impact Tester?

• Falling Dart impact testers come with different configurations. To choose the best one,
• Understand your purpose and check whether the machine is fulfilling the requirements of your testing or not.
• The machine comes with a designed weight of darts. Check if that suits of test requirement.
• The specimen holding clamps are adjustable and allows a variety of samples to get started.

Check how the dart holder works? - Ideally it should work on a pneumatically managed electromagnetic technique which ensures secure hold and quick release of a dart, whenever an action is performed.
