Product Overview

The Plastic Film Drop Dart Impact Tester is a high-precision testing instrument designed to determine the impact resistance and toughness of plastic films, sheets, and flexible packaging materials. By allowing a dart to freely fall from a specified height and strike the specimen, this tester accurately measures the energy or mass required to cause film failure. It is widely used in the packaging, film production, and materials research industries to ensure product quality, durability, and compliance with international standards.

Key Features & Advantages

✅ Compliant with International Standards

• Fully conforms to ASTM D1709 (Methods A & B), ISO 7765-1, and GB/T 9639 test methods.

• Suitable for a wide range of materials including plastic films, composite films, laminated structures, and aluminum-plastic packaging.

• Determines the energy level (or mass) at which 50% of specimens fail under specified impact conditions.

✅ High Precision & Stability

• Accurate free-fall mechanism ensures consistent drop height and impact point.

• Electromagnetic release system minimizes operator error.

• Sturdy frame and high-strength components guarantee long-term mechanical stability and repeatability.

✅ User-Friendly Touchscreen Operation

• Advanced touchscreen control system for intuitive parameter settings such as drop height, dart mass, and test mode.

• Real-time display of impact results, failure counts, and statistics.

• Automatic data recording, calculation, and report generation minimize manual handling.

✅ Safety & Maintenance

• Equipped with a protective safety enclosure and two-hand operation trigger to prevent accidental dart release.

• Pneumatic clamping system ensures the specimen is securely held in position.

• Modular design allows easy replacement of darts, weights, and accessories for quick maintenance.

✅ Data Management & Connectivity

• Internal memory stores multiple test records.

• Export results via USB, RS232, or network connection for further analysis.

• Optional software enables data tracking, statistical evaluation, and report printing in PDF or Excel format.

Testing Principle (How It Works)

1. Cut the film sample to the required size and place it on the clamping fixture.

2. Set the test method (A or B) and select the dart mass or initial energy level.

3. The dart is automatically released to free-fall and impact the specimen.

4. Observe whether the sample fails or remains intact.

5. Continue testing according to the staircase method until the critical impact energy is determined.

6. The system calculates the mean failure energy and generates a complete report.

Optional Accessories

• Different dart head materials (steel, aluminum, phenolic resin, stainless steel)

• Standard weight sets for both Method A and Method B

• Data analysis software for PC connection

• Calibration kits and maintenance tools

• Optional high-energy impact configuration for thicker films
