Product Features Notes1

• Menu interface, color touch screen operation, convenient and fast to set test parameters.
• Two test modes A and B are provided, and the test status is automatically judged.
• The falling dart adopts the principle of electromagnetic hanging, which can release automatically, effectively avoiding the system error caused by human factors.
• Pneumatic sample clamping, manual and pedal dual start mode, built-in observation lamp unique design; convenient, fast and accurate operation.
• Professional computer software supports the functions of multi unit display of test results, graphic display of test process, output and print function, showing the results clearly and intuitively.
• Micro printer and standard RS232 interface make the tester convenient for the external connection and data transmission between the system and the computer.

Testing Principle

At the beginning of the test, select the test method as the first procedure, estimate an initial mass and 3m value, and conduct the test. If the first sample is damaged, the weight 3m shall be used to reduce the falling mass; if the first sample is not broken, the weight 3m shall be used to increase the falling mass for test in turn. In short, the use of weights to reduce or increase the falling mass depends on whether the previous sample is damaged. After 20 samples are tested, the total number of damaged samples is calculated. If n is equal to 10, the test is completed; if n is less than 10, continue the test after supplementing samples until n is equal to 10; if n is greater than 10, continue testing after supplementing samples until the total number of undamaged samples is equal to 10. Finally, the system automatically calculates the impact results.

Test Applications

Basic Applications
Film & Sheet It is suitable for testing the impact resistance of plastic film, sheet and composite film with thickness less than 1 mm. Such as PE film, wrapping film, PET sheet, food packaging bags of various structures, heavy packaging bags, etc
Aluminum Foil, Aluminum Plastic Composite Film It is suitable for testing the impact resistance of aluminum foil and aluminum plastic composite film
Paper and Paperboard Test It is suitable for testing the impact resistance of paper and paperboard
Extended Applications
Drop Ball Impact Test It is suitable for the drop ball impact test of the sample. The sample is clamped on the falling ball impact test fixture, and the falling ball of certain quality is selected to impact the sample from a certain height. The damage of the sample is checked and the impact resistance of the sample is judged
Shoulder Lining Impact Test It is suitable for the falling dart impact test of shoulder lining. Put the shoulder lining sample on the special test fixture, select a certain quality dart head to impact the shoulder lining sample from a certain height, and judge the impact resistance of the sample according to the sample damage

Accurate Impact Testing for Plastic Films

This apparatus delivers consistent and accurate measurements of impact resistance for plastic films using gravity-driven free-fall hammers and advanced sensors. Its compliance with ASTM D1709 and IS 2508 assures reliable, industry-standard results. Its robust construction and digital display provide ease of use and clear data interpretation, making it ideal for quality control in both laboratory and manufacturing environments.


Flexible and User-Friendly Design

With interchangeable hammer weights ranging from 300 g to 2,000 g and an adjustable drop height (up to 1,000 mm), users can tailor tests to specific film types and thicknesses. The pneumatic clamping system ensures secure specimen hold, while the intuitive manual and pneumatic controls simplify operation. The internal memory, storing up to 50 results, streamlines data management and reporting.


Enhanced Safety and Durability

Equipped with a powder-coated body, corrosion-resistant stainless steel impact plate, and a reliable guard with interlock safety mechanism, this impact tester emphasizes operator protection and long service life (>10,000 cycles). Its quiet operation (<65 dB), along with rigorous design for vibration-free installation, makes it a safe and durable addition to any test facility.
