IV. Functions and Applications:

This series of testing machines is a crucial instrument for evaluating the physical, mechanical, process, and structural seismic strength properties of various materials and their products under diverse environmental and simulated conditions. It can perform tests on metallic or non-metallic materials, including tensile, compressive, bending, and shear tests, according to relevant standards. The machines can measure performance indicators such as tensile strength, yield strength, specified non-proportional extension strength, and elastic modulus. Additionally, they offer closed-loop control functions, including constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain.

The design of this testing machine takes into account the possibility of expanding and assembling other fixtures to complete more tests. For example, installing a high-temperature furnace allows for high-temperature tensile tests; equipping with bolt fixtures enables bolt tensile and load-holding tests; equipping with shear fixtures allows for round bar shear strength tests; adding bending, shear, splitting, and elastic modulus instruments in the compression space enables concrete and cement sample tests; and equipping with specialized fixtures such as steel balls, anchor chains, and fasteners allows for various tests of corresponding products.

This testing machine is precise, powerful, easy to operate, stable, and reliable. It can be widely applied in various industries such as universities, research institutes, testing institutions, aerospace, military, metallurgy, machinery manufacturing, transportation construction, and construction materials for precision material research, material analysis, material development, and quality control. It can also be used for process qualification and performance verification tests of materials or products.
