The measurement principle and advantages of shore hardness testing machines, and the historical background of the development of the spring industry.
[Reproduction Private Spring Preparatory School Lecture 4] A different measurement method! Explanation of the Shore durometer applying the principle of rebound.
Today, let's study the last remaining Shore hardness testing machine. This hardness testing machine is called a rebound type, and it is completely different from the previous indentation hardness testing machines. The rebound type means that when a golf ball is dropped onto the floor, it bounces back, but the height of the bounce changes depending on the type of floor. For example, if you place a towel on the floor, the bounce height will be different. In other words, when a ball is dropped from a certain height, it will bounce back higher on a hard floor and lower on a soft floor. The Shore testing machine applies this principle. *For more detailed information, please refer to the PDF. If you have any questions, feel free to contact us.*
