Metal Wire Repeated Bending Testing Machine – High Precision for Steel Wire and Cable Bending Performance Testing

📌 Metal Wire Repeated Bending Testing Machine Overview

The Metal Wire Repeated Bending Testing Machine is designed by our company in strict accordance with GB/T238-2013 “Test Methods for Repeated Bending of Metallic Wire” and GB/T21839-2019 “Test Methods for Prestressed Concrete Steel.” It is primarily used for repeated bending tests of metal wires to evaluate their plastic deformation performance and detect potential defects.

It is suitable for various types of metal wires and can simulate the repeated bending state of the wire during actual use, thereby assessing its long-term durability. When equipped with a sheet clamping device, the Metal Wire Repeated Bending Testing Machine can also perform bending tests on sheet metal samples, making it widely applicable across various industrial fields.

This equipment features high-precision testing capabilities, allowing it to conduct bending experiments on metal wires of different specifications, testing their fatigue strength and durability. It provides scientific data for various industries, helping manufacturers understand and evaluate the bending resistance of metal wires, as well as whether the wire will fracture or permanently deform after repeated bending.

The Metal Wire Repeated Bending Testing Machine precisely measures and records the repeated bending process of the metal wire, ensuring reliable test results and providing strong support for further optimizing product design and manufacturing processes.

The machine is carefully designed and equipped with a high-precision testing system, capable of conducting stable and reliable repeated bending tests. It is particularly suitable for quality testing in industries such as steel wire rope production, electrical cable manufacturing, and construction, meeting the standard testing requirements for various types of metal wires.

The equipment supports test diameters ranging from φ1 to φ12mm, and with special fixtures, it can also test wires of other sizes, providing high adaptability and flexibility to meet the needs of different customers.

This testing machine is widely used in the steel, construction, and manufacturing industries, as well as by manufacturers of steel ropes, electrical cables, and other metal wire products. It is especially suitable for the production of steel wire ropes, electrical cables, and the quality testing of other metal wires, helping companies better control product quality, improve production efficiency, and enhance their market competitiveness.
