Compression Spring Testing Machine

The compression spring testing machine applies axial pressure to the spring via a motor-driven platen, measuring the relationship between deformation and load. It is used to test the stiffness, compression amount, and fatigue life of springs, and is suitable for quality control in industries such as automotive and machinery.
Selection
When selecting, confirm that the maximum test force covers the spring's ultimate load, and ensure the stroke meets the compression requirements. Consider test accuracy and speed, and choose the platen fixture to match the spring's end structure. Ensure the spatial dimensions fit the installation location and that the data interface is compatible with the existing system.

Don't confuse the A-type, D-type, and AX-type Shore durometers for measuring rubber hardness.
The Shore durometer measures hardness by assessing the depth to which the indenter penetrates the material under the force of a spring, with higher values indicating greater material hardness. The main differences between Type A, Type D, and Type AX lie in the shape of the indenter and the magnitude of the spring force, making them suitable for materials within different hardness ranges.
