Test equipment is the key equipment to test the destructive ability of materials, such as drop hammer testing machine, which relies on free fall impact test to check whether the materials are qualified. However, the destructive force of the drop weight test is strong, and the equipment will be directly damaged if there is no appropriate energy absorption device. Reoshoc heavy-duty buffer can design appropriate orifices according to the impact weight and height, so that the buffer can absorb the mechanical energy generated during the impact test, protect the equipment and prolong the service life.
