Falling Weight Impact Tester LFWIT-A10

Labtron’s Falling Weight Impact Tester is used to determine the impact resistance of plastic films, sheets, and other thin materials. This is essential for industries such as packaging, film manufacturing, and quality control, where material strength and durability need to be assessed. It simulates real-world impact conditions by dropping a weighted dart from a controlled height onto the test sample. By measuring the force required to cause failure, manufacturers can ensure their materials meet industry standards and perform well under practical usage conditions.

Our Falling Weight Impact Tester adheres to several international testing standards, ensuring accurate and reliable results. These include ISO7765-1, which specifies test methods for determining the impact resistance of plastic films and sheets, and ASTM D1709, which focuses on the free-falling dart impact test for plastic films. Additionally, it complies with GB/T9639 and JIS K7124, making it suitable for global applications. These standards guarantee that the results obtained are consistent and comparable with industry benchmarks, ensuring the material meets required performance specifications.

This Falling Weight Impact Tester operates by dropping a dart of a specified weight from a fixed height onto a plastic film or sheet. It can perform tests using A and B methods. In Method A, the dart is dropped with an initial weight, and additional weights are adjusted based on whether the sample fails or withstands the impact. Method B follows a similar approach but uses a different dart head design. A microcomputer-based system records and analyzes the data, providing precise and automated results. The system determines the minimum force required to cause material failure, which helps manufacturers evaluate the durability of their products.

Our Falling Weight Impact Tester is primarily designed for testing plastic films and sheets used in packaging, industrial applications, and protective coatings. However, it can also be used to assess the impact resistance of thin flexible materials such as laminated films, composite sheets, and other non-metallic lightweight materials. The test results help manufacturers determine whether a material can withstand mechanical stress and impacts during handling, transportation, and end-use applications.

Safety is crucial when operating the Falling Weight Impact Tester. Operators should always ensure that their hands and other body parts are clear of the testing area before starting a test to avoid injury from the falling dart. Proper eye protection should be worn to prevent accidental exposure to debris from failed samples. The tester should be securely placed on a stable surface to prevent tipping or movement during testing. Additionally, the pneumatic fixture should be checked before each test to ensure the sample is securely clamped. Regular inspection of the dart and other moving parts will help prevent mechanical failures that could pose safety risks.
