What is a Tensile tester?

A tensile testing machine is a device used to measure the tensile strength and elongation of materials such as metals, plastics, fibers, and rubber. During the test, a sample (usually in the form of a narrow strip) is pulled from both ends until it breaks, and the force (tensile force) and deformation (elongation) are measured. The results reveal key material properties such as tensile strength, yield point, maximum tensile stress, reduction in area, and elongation at fracture. This information is essential for evaluating the durability and deformation resistance of a product in its intended use environment. Tensile tests are widely used in quality control, product design, and reliability testing, especially for automotive parts, construction materials, and aerospace components. The tests are often conducted according to international standards such as ISO or JIS.

Application of Tensile tester

１．Metal components – such as steel rods, wires, and plates used in construction, automotive, and aerospace industries to evaluate their strength and durability under stress.
２．Plastics – like polyethylene, polypropylene, or ABS used in consumer products, packaging materials, and automotive parts, to test how they deform under load.
３．Fibers – such as nylon or polyester used in textiles and ropes, to assess their tensile strength and elasticity.
４．Rubber – such as elastomers used in seals, tires, and gaskets, to determine how they stretch and return to their original shape.
