How to Improve Plastic Film Drop Dart Impact Strength ?
Plastic films and sheets are widely used in the packaging industry, construction industry, agriculture, and many other areas. Due to their weak structural properties, plastic films and sheets are susceptible to external impacts and pressures that can cause them to break or fail in practice, and GESTER recognises that dart impact testing is an effective way of evaluating the resistance of these materials to damage from external impacts, ensuring that they remain stable and safe during production, transport and use.
Through this testing, manufacturers can ensure that the quality of their products meets standards, increase their durability, and reduce safety hazards or economic losses caused by packaging breakage.
TheDrop Dart Impact Tester for Plastics Film is an important piece of test equipment used to solve the problem of packaging materials falling and breaking. It simulates a free-fall impact to test the impact resistance of packaging materials and assesses their breakage when dropped or impacted. The following is a detailed introduction to the plastic films drop dart tester:
Before starting the test, choose test method, and estimate an initial mass and Δm. Start the test. If the first specimen fails, decrease the mass of the falling dart by Δm. If the first specimen is not a failure, increase the mass of the falling dart by Δm. Continue the test according to this rule. In brief, increase or decrease by Δm according to whether the former specimen is a failure or not. After 20 specimens, calculate the total number of failed specimens N. If N equals to 10, the test is over. If N is less than 10, add specimens and continue to test until N equals to 10. If N is greater than 10, add specimen and continue the test until the number of non-failure specimens reaches 10. Then the tester calculates the test results automatically according to specific formulas.
Wide applicability: Impact resistance test of plastic films, sheets and composite films e.g. PE preservative films, wrapping films.
High testing accuracy: The plastic films drop dart tester adopts advanced sensors and control system, which can precisely control the release height and impact speed of the falling dart to ensure the accuracy and reliability of the test results.
Simple operation: The plastic films drop dart tester has an intuitive operation interface and simple operation procedure, users only need to follow the prompts to complete the test.
High degree of automation: Part of the falling dart impact tester is equipped with automatic calculation system, which can automatically judge the test status, calculate the impact results and print the test report, greatly improving the test efficiency and accuracy.
The test method of falling dart impact tester usually includes the following steps:
Specimen preparation: according to the requirements of the test standard, cut a certain size of the specimen and attach it to the chuck.
Selection of test method: According to the test requirements, select either method A or method B. Method A is usually used for testing lighter packaging materials, such as plastic film, while method B is used for testing heavier packaging materials, such as cardboard or laminated film. According to the selected test method add the appropriate amount of weights to the dart head to achieve the initial mass, and then release the falling dart to perform the impact test.
Starting the test: After activation, the falling dart is released freely from a given height and impacts on the specimen. Observe and record the breakage of the specimen and conduct multiple tests as required.
Result processing: the system automatically calculates the impact results and displays them so that the user can print the test report as required.
The Drop Dart Impact Tester for Plastics Film is widely used in packaging, food, medicine, plastic, paper products and other industries. By testing the impact resistance of packaging materials, it can assess the impact and drop effects that they may be subjected to during transport, storage and use, so as to ensure the safety and integrity of the products.
Before using the Plastic Films Drop Dart Tester, you should read the manual of the equipment carefully to understand the performance and operation method of the equipment.
During the testing process, it should be ensured that the specimen is firmly and reliably loaded to avoid the specimen falling off or moving during the impact process.
Regular maintenance and repair of the Plastic Films Drop Dart Tester to ensure the normal operation of the equipment and the accuracy of the test results.
In summary, the Drop Dart Impact Tester for Plastics Film, as an important testing equipment, has significant advantages in solving the problem of packaging materials falling and breaking. Through scientific and accurate testing methods, the impact resistance of packaging materials can be assessed, providing strong support for product design and improvement.
