Product Introduction 
The box slide angle tester employs an electric automatic tilting principle. The tested boxes (filled with actual contents) are neatly stacked on the testing platform. Once started, the platform tilts automatically at a constant speed of 1.5°/s. As the tilt angle increases, the downward sliding force on the upper box gradually increases. At the critical moment when the upper box begins to slide relative to the lower one, the digital display locks and shows the current angle, which is the slide angle. This value directly reflects the coefficient of friction between box surfaces and the stacking stability, providing quantitative data for packaging design and logistics safety assessment.

Key Features 
Standard Constant Tilting Speed Tilts at a standard constant speed of 1.5°/s, ensuring consistent test conditions and highly comparable data.
Digital Angle Real-Time Display Equipped with a digital angle display system showing real-time tilt angle with instant angle lock at the moment of sliding for intuitive and accurate readings.
Automatic Tilt Control Electrically controlled automatic tilting process eliminates manual operation, improving test efficiency and repeatability.
Simulates Real Working Conditions Tests are performed using boxes filled with actual contents, faithfully reproducing the stress conditions encountered during logistics and transport.
Simple and Safe Operation One-touch start initiates the test; the platform tilts automatically and locks the angle, requiring minimal operator training and ensuring safety.
Robust and Durable Construction Solid overall structure with dimensions of 950×720×650 mm, suitable for long-term use in both laboratory and production floor environments.
Wide Applicability Suitable for slide angle testing of various corrugated boxes, cartons, and similar packaging containers.
Packaging Safety Assessment Provides critical data support for box stacking design, transport safety evaluation, and packaging material selection.

Main Technical Specifications

FAQ 
1. Is it necessary to test with boxes filled with actual contents?
Yes. To faithfully simulate the actual stress conditions during transport and storage, boxes must be filled with actual contents. Empty boxes have significantly different surface friction characteristics and weight distribution compared to loaded boxes, and test results would not be representative.

2. What is the acceptable standard for slide angle?
Acceptable slide angle standards vary by industry, product type, and logistics conditions, and are generally set by individual companies based on their packaging specifications and transport environment. Generally, a larger slide angle indicates better stacking stability. It is recommended to refer to relevant industry standards or set acceptance thresholds based on actual logistics conditions.

3. Is the tilting speed of 1.5°/s adjustable?
The standard tilting speed is 1.5°/s, a commonly used parameter that simulates gradual tilting conditions in actual logistics. For other tilting speed requirements, please consult our technical team for customization options.

4. What size boxes can the testing platform accommodate?
The testing platform accommodates boxes with overall dimensions within 950×720 mm. Two identical boxes must be neatly stacked with the upper box completely resting on the lower box. Boxes extending beyond the platform edges may affect testing accuracy.

5. How to determine when the upper box begins to slide?
The moment when the upper box shows visible displacement relative to the lower box is typically observed visually as the slide starting point. The digital angle value should be read or locked immediately at that moment. For cases where the sliding process is subtle, multiple repeat tests can be performed and the average value taken.

6. Does the instrument require periodic calibration?
The instrument is factory-calibrated for angle accuracy. Routine angle accuracy verification can be performed using an inclinometer or spirit level. If angle display deviation is detected, contact our after-sales service for professional calibration.
