Dart Impact Tester
The Digital Dart Impact Tester stands as a sophisticated yet cost-effective engineering solution designed specifically for evaluating the impact resistance of thin sheet materials. Engineered for versatility, the equipment is available in both bench-mounted and floor-standing configurations, meticulously designed to accommodate the varying drop heights and specific dart requirements mandated by ASTM D1709 Methods A and B. The core functionality revolves around expressing impact resistance as the precise mass of a free-falling "missile" that results in the failure of 50% of the tested specimens. By utilizing a streamlined pass/fail procedure in conjunction with a series of incremental weights, operators can accurately calculate the resulting failure mass. This system is built to account for critical variables such as material thickness, uniformity, and sample clamping pressure, ensuring that every test provides a repeatable and scientifically valid data point for quality assurance.
Product Overview
This specialized testing equipment serves as a vital tool for assessing the quality and structural integrity of films and laminates regarding their resistance to rupture caused by sudden, high-velocity impacts. It is widely recognized as an essential instrument for the packaging and polymer industries, where the durability of materials is non-negotiable. The tester is capable of analyzing a diverse range of substrates, including plastic films, flexible packaging, paper, paperboard, corrugated board, and various metal foils. By simulating real-world stresses—such as those encountered during the dropping or rough handling of packaged goods—the Dart Impact Tester provides manufacturers with the critical insights needed to optimize material strength and prevent product failure. Its robust construction and adherence to international testing protocols make it an indispensable asset for any quality inspection department or chemical laboratory focused on high-performance material standards.

Advanced Features
Hands-Free Sample Clamping
Equipped with a heavy-duty Foot-Operated Switch to clamp and un-clamp the film samples. This allows the operator to use both hands for precise specimen alignment, ensuring wrinkle-free testing.
Electromagnetic Release Control
Features a specialized Umbrella Switch to activate and de-activate the high-power Electromagnet Coil. This ensures a friction-free, instantaneous release of the dart for consistent gravitational velocity.
Inbuilt Vacuum Clamping System
Integrated with a powerful inbuilt vacuum pump that facilitates superior sample clamping. This system prevents material slippage during impact, maintaining the integrity of the ASTM D1709 testing protocol.
Dart & Equipment Protection
The catching pit is lined with high-density Foam Padding to protect the precision-engineered falling dart from damage upon impact. This extends the lifespan of the darts and prevents calibration shifts.
