Stamping Blanks

Pre-cut metal sheets ready for stamping into final parts.

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
