What is contoured-stampings？

Contoured stampings are precision-formed metal components with complex 3D surfaces produced through stamping dies, achieving ±0.1mm profile accuracy. Widely used in automotive bodies, aerospace structures and industrial design products.Stainless Steel Compression Springs

Key Advantages

Complex Curving

Achieves 5-7 directional 3D deformation in single stroke.

Ultra Precision

Maintains ±0.05mm profile tolerance.

Material Efficiency

Smart nesting reduces scrap by 35%.

Surface Quality

Mirror-polished dies deliver Ra0.1μm finish.

Strength Enhancement

Strain hardening increases local strength 40-60%.

How They Work

Metal sheets plastically deform to replicate die contours under hydraulic/mechanical pressure, with controlled material flow to prevent cracking.

Key Characteristics

✔️

Material Thickness - Processes 0.3-6mm various metal sheets

✔️

Forming Depth - Maximum 8-10x material thickness

✔️

Springback Control - AI compensation achieves ±0.2° accuracy

Key Design Factors

✔️

Die Clearance – Optimal 1.05-1.15x material thickness gap

✔️

Blank Holder Force – Multi-zone control with ±2% tolerance

✔️

Lubrication – Nano-lubrication with ±20nm film control

Manufacturing Process

Sheet Pretreatment

Laser cleaning removes surface oxides.

Precision Blanking

Servo cutting ensures ±0.03mm accuracy.

Preforming

30-50% initial deformation creates basic profile.

Fine Stamping

2000-3000T pressure forms final contours.

Trimming/Piercing

5-axis laser cutting finishes edges.

Local Strengthening

Laser shock peening reinforces critical areas.

Dimensional Inspection

Full 3D optical scanning.

Surface Treatment

Nano-coating or electropolishing.
