Description

Technical Field

[0001] The utility model relates to the technical field of tensile machines, in particular to a tensile machine. Background Art

[0002] A tensile testing machine, also known as a universal testing machine, is a device used to test the mechanical properties of materials. Its diverse capabilities allow it to perform tensile and compression tests on a wide range of materials. It features high precision and utilizes advanced sensors and control systems.
