Automotive Wire Repeated Bending Tester - China

The Automotive Wire Repeated Bending Tester is designed to evaluate the durability of automotive wires under repeated bending conditions.

It can be combined with a low-temperature chamber to perform bending tests under various environmental conditions, simulating real-world automotive wiring stress.

Application

(1) Automotive wiring harnesses – assess flexibility and resistance to repeated bending.

(2) Low-voltage cables – verify insulation and conductor integrity under cyclic mechanical stress.

(3) R&D laboratories – test new wire formulations for mechanical reliability.

(4) Production quality control – ensure wires meet bending durability standards.

(5) Environmental testing – evaluate performance under low-temperature conditions using an optional temperature chamber.
