1. Application and Purpose of Drop Testing Machines:
With the rapid development of the logistics industry, paper boxes and packaging materials often suffer from collisions and falls during transportation. Drop testing machines are mainly used to simulate the impact of falls on packaging materials during transportation and handling, to evaluate the impact resistance of packaging materials and the validity of packaging design. Drop testing machines are widely used in areas such as commerce, inspection, enterprises, technical supervision agencies, and schools. They can perform face drops, corner drops, and edge drops. By simulating falls at different angles and heights, the damage of the product can be understood, and the maximum height and impact resistance during a fall can be evaluated. Based on the results of the test, packaging design can be improved and perfected to enhance the protective performance of the product.
2. Working Principle of Drop Testing Machines
Drop testing machines are used to evaluate the vertical impact resistance of packaging and their ability to protect packaged contents. They conduct tests by dropping packaging materials from specified heights onto a hard, flat horizontal surface. During the test, the relevant parameters are controlled by adjusting the device, based on the height to be tested, allowing the packaging to freely fall and collide with the impact surface. This testing method can simulate the falls that products may experience during transportation.
The scope of application for drop testing machines includes:
• Simulating repeated free falls that connectors, small remote devices, and other products may experience while loaded on cables.
• Drop testing for packaging.
• Free falls that products may experience during transportation in a non-packaged state.
3. Classification of Drop Testing Machines
Drop testing machines are primarily divided into three types: zero drop testing machines,  single-arm drop testing machines, and double wing package drop test equipment.
•  Zero drop testing machines are mainly used to assess the effects of actual transportation and handling on packaging materials, and to evaluate their impact strength and the validity of packaging design during handling. They are suitable for drop testing larger packaging and test pieces.
•  Single-arm drop testing machines use a brake motor and chain drive to control the rise and fall of the arm. The drop height is measured using a numerical height scale, ensuring high accuracy and providing a clear display. The operation is simple, and the lifting and falling of the arm is stable, with minimal error in the angle of the drop. They are suitable for all types of manufacturers and quality inspection departments.
•  Double wing package drop test equipment can meet the demands of product resistance during transportation, and thus improve and perfect packaging design. They use a dual-column structure, equipped with spring cushioning devices and a height scale indicator, ensuring stable and reliable operation. They are capable of performing corner drops, complying with the requirements of GB/T4857.5-92 and ISO2248-1972(E) standards.
4. Operating Instructions for Drop Testing Machines
• The drop condition of the test piece can be preset as a face, edge, or corner drop.
• The drop height can be preset, and the test piece will automatically be positioned when it reaches the set height.
• The operating mechanism is flexible, ensuring that the test piece is not disturbed by any external forces during release and free fall, and ensuring that it meets the required drop status.
• The structure of the drop testing machine is scientifically designed, with a safe and reliable inclined impact test platform.
• This machine can perform slanted platform impact testing for transport packaging to determine their impact resistance and the ability to protect contents, as well as free-fall tests for faces, corners, and diamonds.

5. Precautions for Drop Testing Machines
• It is important to ensure that the test piece is not affected by external forces during the falling process.
• Appropriate spacers should be used to ensure that the test piece maintains a horizontal position during the drop.
• When using the inclined test platform, the test piece must be placed on the appropriate end surface.
• When using the drop testing machine, the operating instructions must be followed.
• Maintenance and upkeep of the drop testing machine require careful and cautious operation to prevent damage.
• During drop testing with the drop testing machine, it is important to ensure that the test piece does not cause damage to the equipment and to prevent potential safety hazards.
