Description

Wire Shapes Built Around a Function

Wire forming springs are metal components bent into a defined shape to provide spring action, clamping, positioning, movement transmission or connection. A single wire form can combine the functions of a spring, clip, link or bracket within an assembly.

Round wire is common, while flat wire and other profiles can also be formed. CNC wire bending enables custom 2D and 3D geometries for irregular or confined installation spaces. The geometry is developed around the required function rather than a standard coil shape. Combining functions in one part can reduce component count and simplify assembly, with potential material and assembly cost savings.

Applications for Formed Wire Parts

  • Automotive: seat adjustment mechanisms, seatbelt tongue plates, wiring harness clips and accelerator pedal return mechanisms.
  • Household appliances: washing machine door locks, coffee machine levers, printer paper trays, hinges and appliance door returns.
  • Medical devices: grasping mechanisms in laparoscopic instruments, insulin pump transmission parts and monitoring equipment clips.
  • Consumer electronics: SIM card trays, laptop hinge torque components and wearable-device battery contacts.
  • General machinery: safety-guard triggers and agricultural equipment linkages.

Carbon steel, stainless steel, music wire and copper alloys offer different material choices for a custom form. Define the required shape and mechanical function together with the material, surface treatment and packaging.
