What is Metal Stamping?

Metal stamping is a manufacturing process that uses dies and high-pressure presses to shape flat metal sheets into specific forms. It involves operations such as punching, blanking, bending, embossing, flanging, and coining to produce parts with precise dimensions and complex geometries. Metal stamping is widely used in industries like automotive, aerospace, electronics, and appliances due to its efficiency, consistency, and ability to produce high volumes of components with tight tolerances.

Type of Metal Stamping

Sheet metal bending is extensively utilized in numerous industries for its high precision, rapid processing, and efficient material usage, allowing for the creation of complex shapes with minimal waste.

Piercing

Stamping piercing is a metal stamping process used to punch holes or cutouts into sheet metal using a punch and die. It is fast, accurate, and ideal for high-volume production.

Bending

Used to create L-shaped, U-shaped, or V-shaped parts. The material stays intact (not cut or pierced), just bent. Common in brackets, enclosures, frames, and automotive components.

TonZa Making|Stamping

Coining

The metal flows plastically under the pressure, filling the die completely. This produces crisp edges, fine features, and exact shapes—often on both sides. Used for high-precision parts.

Curling

It is a metal forming process used in sheet stamping to roll or form the edge of a metal part into a circular or curved profile, often to remove sharp edges or improve the part's strength and appearance.

Embossing

It is a metal forming process that creates raised or recessed designs on a sheet metal surface without cutting or removing any material. It’s widely used in both industrial and decorative applications.

Design Guidelines

Optimize your designs for manufacturability with our expert guidelines and feedback, ensuring the best results in injection molding service

Material Selection

1. Choose materials suitable for stamping:

Carbon steel, stainless steel, aluminum, copper, brass Consider formability, strength, and corrosion resistance for your application

2. Recommended thickness: 0.2 mm – 6.0 mm

Part Geometry

1. Simplify the design to reduce tooling cost and processing time

2. Avoid unnecessary bends or deep draws unless required

3. For deep-drawn parts, maintain a smooth wall-to-base transition (use radius)

Bending Guidelines

1. Minimum flange length: at least 4× material thickness

2. Bend radius: ≥ 1× material thickness to avoid cracking

3. Avoid placing holes too close to bends (distance ≥ 2× thickness + bend radius)

Hole and Slot Design

1. Minimum hole diameter: 1.2× material thickness

2. Minimum distance between holes: 2× thickness

3. Avoid placing holes or slots too close to edges

Deep Drawing Tips

1. Max drawing depth: up to 3× part diameter (depending on material)

2. Use generous radii at corners and transitions

3. Uniform wall thickness preferred

Draft Angles

1. Add small draft angles if parts need to be removed from a die or form

2. Especially important for deep drawn or formed shapes

Avoid Sharp Corners

Use rounded edges (radius ≥ 0.5 mm) to reduce stress concentration and tool wear

Marking & Identification

1. Add engraving or embossing for part number, batch, or logo (if needed)

2. Ensure text height ≥ 1 mm and depth ≤ 0.2 mm

Progressive die stamping performs multiple operations in one press stroke across multiple stations, ideal for high volumes. Single-stage (or single-hit) stamping does one operation per stroke, suited for small production runs.

What tolerances can be achieved with stamping?

Tolerances depend on material, tooling, and design, but precision stamping can achieve tolerances as tight as ±0.01 mm with proper control.

How can I reduce stamping costs?

Costs can be reduced by optimizing part design for manufacturability, using standard materials, minimizing tight tolerances, and ordering higher volumes.

What is the lead time for stamped parts?

Lead time depends on complexity, volume, and tooling. Prototype runs may take 1–2 weeks, while production tooling and delivery can take 4–6 weeks.

Do you offer design support for stamped parts?

Yes, we provide DFM (Design for Manufacturability) assistance to help optimize your design for efficient, cost-effective stamping.
