Bend Testing Apparatus

The bending test instrument applies force to the specimen through three-point or four-point loading methods, causing it to bend and deform until fracture, while measuring flexural strength and deflection. It is used to evaluate the mechanical properties of materials under bending loads, commonly employed in quality control and research and development testing for materials such as metals, plastics, and wood.
Selection
When selecting a bending tester, consider the material type and standard requirements, match the maximum load with precision, confirm the fixture compatibility with sample dimensions, check the functionality of the data acquisition system, evaluate the equipment's safety protection and maintenance convenience, and refer to actual testing needs and budget constraints.
