What Is Metal Stamping?
Metal stamping is a cold-forming manufacturing process that uses a stamping press and custom tooling (dies) to shape metal sheets into specific geometries. Depending on the part design, stamping may involve a single operation or a progressive sequence of steps performed in one press cycle.
Key characteristics:
High repeatability and dimensional consistency
Extremely low per-unit cost at medium to high volumes
Excellent compatibility with automation and inline inspection
Our Metal Stamping Capabilities
To support a wide range of industrial requirements, our metal stamping services cover multiple process types and production scales.
Stamping Processes We Offer
Progressive Die Stamping: Multiple operations performed in sequence within one die set, ideal for high-volume, complex parts.
Transfer Stamping: Individual parts transferred between stations, suitable for larger or deeper-formed components.
Deep Draw Stamping: Controlled forming for cups, housings, and enclosures with high depth-to-diameter ratios.
Blanking & Piercing: High-speed cutting operations for precise outer profiles and internal features.
Forming & Bending: Secondary or inline operations to achieve functional angles and contours.
Materials Supported
Our metal stamping services support a broad range of ferrous and non-ferrous metals:
Carbon steel & alloy steel
Stainless steel (304, 316, 430, etc.)
Aluminum alloys
Copper & brass
Phosphor bronze and spring steel
Material thickness typically ranges from 0.1 mm to 6.0 mm, depending on geometry and alloy strength.
Advantages of Metal Stamping
Metal stamping is ideal for high-volume production of complex metal parts. Once tooling is completed, it delivers excellent consistency and cost efficiency.
Supports complex geometries and contoured features
Scales efficiently from thousands to millions of parts per year
Processes such as fine blanking enable precision forming of thicker metal sheets
Very low cost per part in mass production
Disadvantages of Metal Stamping
The main drawbacks of metal stamping relate to upfront investment and initial lead time.
Longer lead times for first parts due to die design and fabrication
Higher initial costs for tooling, fixtures, and non-recurring engineering (NRE)
Die iterations may be required to ensure stable, repeatable production
Tooling & Die Engineering
Tooling quality directly determines stamping efficiency, part accuracy, and die life. Our in-house die engineering team designs and manufactures stamping dies with a focus on:
Optimal material flow and strain distribution
Long tool life for mass production
Easy maintenance and reduced downtime
Compatibility with automated feeding systems
We support progressive dies, compound dies, and single-stage dies, tailored to your production volume and cost targets.
Quality Control & Tolerances
Consistency is the core advantage of professional metal stamping services. Our quality system ensures stable output throughout long production runs.
Quality measures include:
First Article Inspection (FAI)
SPC-based in-process monitoring
Dimensional inspection using CMM and optical measurement
Material certification and traceability
Typical tolerances:
±0.02 mm to ±0.05 mm for critical features (depending on material and design)
Types of Metal Stamping
We offer a full range of metal stamping processes to match different part geometries, materials, and production volumes. By reviewing your 3D models and technical drawings, our engineers select the most efficient stamping method for your application.
Progressive Die Stamping
Uses multiple stations within a single die to perform sequential operations. Ideal for high-volume production of complex parts, commonly used in automotive and industrial applications.Transfer Die Stamping
Similar to progressive stamping, but parts are transferred between stations individually. Suitable for larger or deeper-formed components.Deep Draw Stamping
Produces parts with deep cavities such as housings and enclosures. The process enhances structural rigidity through controlled material deformation.Four-Slide (Multi-Slide) Stamping
Forms parts from multiple directions, enabling intricate geometries. Commonly used for small precision components in electronics, medical, aerospace, and automotive industries.- Embossing
Creates raised or recessed patterns for functional or decorative purposes.
Hydroforming
Uses high-pressure fluid to form metal sheets over a die, achieving uniform thickness and complex shapes. A trimming operation is typically required after forming.Blanking & Fine Blanking
Blanking cuts flat parts from sheet metal, while fine blanking delivers smooth edges and high dimensional accuracy for precision components.Punching
Removes material from the workpiece to create holes or internal features.Coining
Applies high pressure to form small features, improving surface finish and work-hardening the material.Bending & Flanging
Forms angles or tabs along a single axis, commonly used for U-, V-, or L-shaped profiles.
