Custom SUS304 Wire Form Ear Hook Spring CNC 2D Wire Bending Bluetooth Headset Metal Ear Support

Our custom wire form ear hook spring, also known as CNC wire bending ear hook and bluetooth headset metal ear hook, is a precision 2D wire forming component specially designed for open-ear wireless Bluetooth headsets. Made from high-tensile 304 stainless steel spring wire, each ear support is fully shaped by automatic CNC 2D wire bending machines in one single process to form standard C-shaped arc with integrated end hook.

After forming, parts go through tumble grinding to remove sharp burrs and cutting edges, followed by stress relief heat tempering to lock stable memory shape and eliminate internal bending stress. Final surface treatment includes electrolytic polishing and passivation to boost anti-rust performance and smooth touch.

As a reliable OEM manufacturer, we provide full custom service for all sizes, wire diameters, arc radii and hook structures. Every finished stainless steel wire forming ear support is 100% inspected on dimension and elasticity before packaging and delivery.
