◆ Product Introduction:

    This testing machine is a crucial instrument for evaluating the physical, mechanical, and process properties, structural seismic strength, and internal and external defects of various materials and their products under diverse environmental and simulated conditions. It can conduct tests on metallic or non-metallic materials, including tensile, compressive, bending, and shear tests, according to relevant standards. It can measure performance indicators such as tensile strength, yield strength, specified non-proportional extension strength, and elastic modulus of the tested materials. It offers closed-loop control functions, including constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain, enabling process qualification verification tests for materials or products.

    This series of testing machines is an important instrument for testing the physical properties, mechanical properties, process performance, structural seismic strength, and internal and external defects of various materials and their products under various environmental and simulated conditions. It can perform tests on metallic or non-metallic materials according to corresponding standards, including tensile, compressive, bending, and shear tests. It can measure performance indicators such as tensile strength, yield strength, specified non-proportional extension strength, and elastic modulus of the tested materials. It can achieve closed-loop control of equal rate loading, equal rate deformation, equal rate displacement, and equal rate strain.

    It is primarily used for tensile, compressive, bending, and other mechanical property tests of materials such as metals, non-metals, structural components, concrete, and ceramics. It measures performance parameters such as ReH (upper yield strength), ReL (lower yield strength), Rp (specified non-proportional tensile strength), Rt (specified total tensile strength), Rm (tensile strength), Rr (specified residual tensile strength), and E (elastic modulus).

    The design of this testing machine takes into account the possibility of expanding and assembling other fixtures to complete more tests. Equipped with bolt fixtures, it can perform bolt tension and load-holding tests; equipped with shear fixtures, it can conduct round bar shear strength tests; in the compression space, additional fixtures such as flexure, shear, splitting, and elastic modulus instruments can be added to perform tests on concrete and cement samples; equipped with specialized fixtures, it can complete various tests for 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.
