Its highly scalable fixture system and automatic control function make universal testing machine not only suitable for high-strength testing of metal materials, but also for performance testing of non-metallic materials such as plastics, rubber, composites, wood, ceramics, etc., with strong versatility and industry adaptability.

Multifunctional integrated design

The Universal Testing Machine (universal testing machine) supports a variety of mechanical performance tests with its modular design and replaceable fixture system, truly achieving "one machine for multiple uses". Users only need to replace the corresponding loading device or clamping fixture to complete different test projects on the same device, greatly improving the utilization efficiency and testing capacity of laboratory equipment.

Tensile test is one of the most basic and widely used mechanical test methods. By fixing the two ends of the specimen with a fixture, the universal testing machine can apply tension in the axial direction until the material breaks. During this process, the equipment will record the stress-strain changes of the material for analyzing its key performance indicators such as yield strength, ultimate tensile strength, elongation and elastic modulus. It is suitable for metal materials (such as steel, aluminum, copper), polymer materials (such as plastics, rubber) and other ductile materials.

Compression test:Compression test is mainly used to test the material's ability to resist deformation and failure mode under axial compression, and to evaluate its compression strength, modulus and ultimate bearing capacity. universal testing machine can be configured with different specifications of pressure plates or cylindrical pressure heads, which are suitable for compression failure tests of brittle materials such as concrete, bricks, foam materials, etc., and are often used in the fields of construction engineering, civil structures and material durability assessment.

Bending test:The bending test is used to examine the flexibility, ductility and resistance to fracture of materials under external bending. The commonly used three-point or four-point bending tooling can simulate the state of actual components bearing bending moments in use, and measure their yield point, maximum bending load, fracture angle and residual deformation. It is suitable for structural materials such as steel bars, steel sections, pipes, plastic sheets, and wood, and is particularly common in the fields of construction and machinery.

Shear and peel tests:Shear and peel tests are mainly used to detect the strength properties of the internal connection interface or joint of the material. In engineering applications such as composite materials, adhesive parts, and welded structures, this type of test is crucial. The shear test evaluates the shear strength of welds, rivets, bolted connections, etc. by loading transverse shear force; while the peel test is used to analyze the adhesion firmness of the adhesive layer (such as glue, coating, and film) under the action of peeling force, which is suitable for thin films, coatings, electronic packaging and other fields.
