If you want to operate this testing instrument then you should start the machine and turn it ON by plugging it in the main socket of the machine in a 3 pin 15 amp socket. Once you start with the machine operation, then we suggest you place the specimen. Take the specimen of plastic film that the user wants to test with the dimensions that allow the specimen to flow out of the clamping unit for at least 25mm. You can also remove the outer clamping ring and separate it from the unit. Now, you can also place the specimen on the inner clamping ring. Put the back of 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. Make sure that the specimen does not have any wrinkles. The specimen must be completely wrinkle-free during the test. It is very important to place the sample correctly so as to get accurate testing results. Now, you can adjust the height of the protective shield of the dart. To set the height of the dart, you can loosen the adjusting knob given with the electromagnetic release mechanism. Adjust the height of the release mechanism according to the test requirement. For testing fix the electro-magnet rod at different length of 660 mm & 1524 mm with formula as: Required length + Dart length + electromagnet length= Scale Reading. After following the above steps, you can commence the test. You can give us more information about this testing instrument by giving us a call.

The dart impact tester is a 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. If you are looking for the best testing instrument for testing the strength of the dart then we suggest you go with Presto dart impact tester. Presto’s Dart Impact Tester is used to determine the impact of load on a plastic film under specific conditions to analyze the effect of a free-falling dart. A load of falling dart damages the plastic film under specified conditions. This testing instrument is widely used in plastic industries for judging the strength and stability of plastic films and similar products. The instrument is provided with an electromagnetic dart hold/release mechanism to avoid any type of interference in force exertion. The electromagnetic mechanism can hold a weight of up to 2 kg. The instrument is also provided with a digital counter that is helpful in determining the number of falls performed in a single test. The dual clamping device provided with the machine is best for providing wrinkle-free clamping of the test specimen. Along with that, there is a shielding device provided with the machine to prevent the dart from bouncing back out of the machine upon impact.

The main purpose of this testing instrument is to improve your packaging quality by testing the strength of plastic films used in the packaging industry. These films are used for shrink wrap, bubble wrap, and so forth. When plastic films are used for the packaging of products, it is essential for the films to be strong enough to provide the best protection to the products packaged within. One of the biggest and major forces that a plastic film has to bear is from freely falling weights. The freely falling weight can really damage the plastic films and hence ruin the whole packaging of a product. The dart impact test method is one of the major testing methods that are used for testing the strength of the films and their ability to bear impact from a freely falling dart. Dart Impact is also known as impact failure load of plastic films is described as the load of the hemispherical shaped dart, falling on the plastic sheet or film held in a suitable clamp from a particular height, which causes the collapse of 50% of samples tested. Dart Impact Tester is a very beneficial tool for clearly controlling peak and normal strength characteristics to speed up the additives and production settings and adjustments, research, and development of sheet and film materials. PRESTO Dart Impact Tester is widely used by plastic film manufacturers for assessing the strength and durability of their plastic films, flexible films, sheets, and similar other products. It works according to both Method-A and Method-B of the test standard. The test comprises dart configuration and drops height with a different weight of the dart. Test results can be used as a quality control evaluation and also for end-use assessments.

The dart is designed in a hemispherical form that can be dropped from uneven heights. It is held by an electromagnetic dart holder which is released by pressing a button from varying heights. A user can set the height of the dart manually. The result can be viewed from the digital panel. Its electromagnetic hold and release mechanism for dart will help you to obtain accurate test results. You can also measure the number of falls during a single test procedure. It has circular annular clamping services for zero slippage of the test specimen during the test. This testing machine contains shielding devices to the prevention of darts from falling out after the bounce back from the specimen. To know more about it, give us a call.
