Key Elements of Metal Stamping

Key Elements of Metal Stamping

Die Design and Manufacturing: Dies are the core of the stamping process. Non-standard parts require customized dies, and the die structure (single-operation die, compound die, progressive die) must be determined based on the part drawings.

Single-operation die: Completes one operation in a single stamping operation; suitable for small batches of simple parts.

Compound die: Completes multiple operations in a single stamping operation (e.g., punching + blanking); suitable for small to medium-sized parts with high precision requirements.

Progressive die: The blank is continuously fed in, completing multiple operations sequentially; suitable for large batches of complex parts.

Stamping Equipment Selection: Equipment is selected based on part size, thickness, and operation:

Small parts: Benchtop punch press (tonnage 10–50 tons).

Medium to large sheet metal parts: Gantry punch press, hydraulic punch press (tonnage 50–500 tons).

Precision parts: High-speed precision punch press (ensuring stamping stability).

Material compatibility varies significantly depending on the metal material's stamping performance. Non-standard customization requires matching materials: Easy-to-stamp materials: low-carbon steel, aluminum and aluminum alloys, copper alloys (good plasticity, low deformation resistance).

Difficult-to-stamp materials: stainless steel, high-strength alloy steel (requires heating or the use of specialized die steel).
