What is Wire Bending?

Wire bending is a manufacturing process that forms metal wires into specific shapes using mechanical force, widely used in automotive parts, electronic components and medical devices. It enables precise forming of complex 3D geometries.Stainless Steel Compression Springs

Wire Bending

The process of precisely bending metal wire into custom shapes.

Key Advantages

High Precision

Forms intricate 3D shapes with multiple angles/radii.

Complex Geometry

Reduces material waste by 90% vs machining.

Material Saving

Reduces material waste by 90% vs machining.

Quick Changeover

CNC program switching in under 5 minutes.

Surface Protection

Non-cutting process preserves wire surface.

How They Work

Wire is fed through guides while bending dies and rotating arms create precise plastic deformation at programmed locations.

Key Characteristics

✔️
Materials - Processes 0.1-12mm steel, copper, aluminum wires
✔️
Angle Accuracy - ±0.5° bending angle tolerance
✔️
Radius Control - Minimum 1xD bending radius

Key Design Factors

✔️
Springback Compensation – 0.5-5° over-bending based on material
✔️
Die Clearance – 5-10% of wire diameter clearance
✔️
Feed Rate – Optimized 10-50m/min based on wire size

Manufacturing Process

Wire Prep

Select straight wires of required material/diameter.

Feeding

Servo motor feeds wire to precise position.

First Bend

Station 1 forms basic angles.

Secondary Forming

Subsequent stations add complex features.

Cutting

Hydraulic shear separates finished part.

Inspection

CCD vision checks 100% dimensions.
