Film Evenness Affects Packaging Impact Resistance performance

Product catalog summary

Overview: The C670M Falling Dart Impact Tester is designed to measure the impact mass and energy required to damage 50% of a plastic film or sheet sample under a free-falling dart. It features a user-friendly interface with a color touch screen and offers two test modes (A and B) for automatic test status judgment.

Product Features:

Electromagnetic hanging principle for dart release to minimize human error.
Pneumatic sample clamping with manual and pedal start modes.
Built-in observation lamp for enhanced operation.
Professional software for multi-unit display, graphic test process display, and data output/printing.
Micro printer and RS232 interface for external connectivity and data transmission.

Testing Principle: The test begins by selecting a method and estimating an initial mass. The mass is adjusted based on whether the sample is damaged, continuing until 20 samples are tested. The test concludes when 10 samples are damaged or undamaged, and the system calculates the impact results.

Reference Standards: ISO 7765-1-1988, ASTM D1709, GB/T 9639.1-2008, JIS K7124-1.

Test Applications:

Basic Applications: Suitable for plastic films, sheets, composite films, aluminum foil, and paperboard with thickness less than 1 mm.
Extended Applications: Includes drop ball impact tests and shoulder lining impact tests.

Technical Parameters:

Measuring Methods: Method A (50-2000g), Method B (300-2000g).
Weight Accuracy: ±0.5%.
Sample Clamping: Pneumatic.
Air Source Pressure: 0.6 MPa (user-provided).
Sample Size: >150 mm x 150 mm.
Power Supply: 220VAC 50Hz / 120VAC 60Hz.
Net Weight: 70 kg.
Dimensions: Method A - 500 mm x 450 mm x 1320 mm; Method B - 500 mm x 450 mm x 2160 mm.

Product Configuration: Standard configuration includes method A setup, touch screen, and micro printer. Optional method B configuration includes professional software and communication cable.

Remarks: The air source interface requires a Φ 8 mm polyurethane pipe, and the air source must be provided by the user. Labthink reserves the right to modify product specifications and provides updates on their website.

C670M Falling Dart Impact Tester C670M Falling Dart Impact Tester is suitable for measuring the impact mass and energy of plastic film or sheet when 50% of the sample is damaged under the impact of free falling dart at a given height. Menu interface, color touch screen operation, convenient and fast to set Two test modes A and B are provided, and the test status is automatically 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 △m value, and conduct the test. If the first sample is damaged, the weight △m shall be used to reduce the falling mass; if the first sample is not broken, the weight △m 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. Reference Standard Note 1 ISO 7765-1-1988, ASTM D1709, GB/T 9639.1-2008, JIS K7124-1
