The drop testing machine can perform free drop tests on the surface, corners, and edges of packaging, equipped with a digital height display instrument and a decoder for height tracking, so as to accurately provide the product's drop height, with an error of no more than 2% or 10mm from the preset drop height. The machine adopts a single arm double column structure, with electric reset, electric drop, and electric lifting devices, making it easy to use; The hydraulic buffering device greatly improves the service life, stability, and safety of the machine. Single arm setup allows for easy placement of products, with a drop angle impact surface and a base plane angle error of less than or equal to 5 degrees. The drop testing machine is divided into small object drop testing machine and packaging drop testing machine. The maximum weight of the test sample for the battery drop testing machine is 2kg ± 100g, while the maximum weight of the test sample for the packaging drop testing machine is 80kg ± 2Kg. The battery drop testing machine is designed to test the damage of product packaging caused by falling and evaluate the impact resistance during transportation and handling. Adopting dual column guidance and adjustable height drop times, it works stably and reliably, and can achieve edge, surface, and corner drops.
