What is Stamping Blanks？

Stamping blanks are precision-processed metal sheets/strips specifically designed for stamping operations, featuring tight tolerances (±0.05mm) and optimized mechanical properties to improve stamping efficiency by over 30%.Stainless Steel Compression Springs

Key Advantages

Material Efficiency

Nesting optimization reduces scrap by 40%.

Dimensional Stability

Pre-hardening guarantees ±0.03mm thickness tolerance.

Surface Quality

Mirror finish (Ra0.2μm) reduces die wear.

Batch Consistency

Auto-sorting ensures 99.9% dimensional uniformity.

Quick Changeover

Standardized interfaces enable 5-minute die change.

How They Work

Precision rolling, shearing and heat treatment processes transform metal coils into standardized blanks with optimized dimensions, hardness and surface properties for stamping.

Key Characteristics

✔️

Material Range - Covers 0.1-6mm stainless, carbon steel and alloys

✔️

Width Tolerance - ±0.05mm precision slitting

✔️

Hardness Control - Adjustable HRC20-50 for various stamping needs

Key Design Factors

✔️

Grain Direction – Rolling direction must align with stamping forces

✔️

Edge Quality – Laser cutting maintains burr height < 0.01mm

✔️

Stress Distribution – Vibration aging removes 98% internal stress

Manufacturing Process
