Custom Stamped Components

Custom stamping is a wider concept than deep drawing. It can be defined in several types and each of the stamping types are aimed for special needs. There is progressive stamping and transfer stamping for high volume productions, single and compound station stamping for prototyping and short run manufacturing. This technology can be utilized in many applications with many more forms of products. At JCL, we leverage decades of expertise in engineering and manufacturing to deliver custom stamping components to our clients' exact specifications.

Stamping Types We Provide

Progressive Stamping: For high-volume production, each press stroke produces a complete part with high precision tolerance.

Transfer Stamping: Ideal for creating large size components, leveraging complex shape forming and maintaining dimensional accuracy.

Compound Stamping: A single stroke determines a feature forming for test runs and prototype evaluations, preparing for mass production.

Precision Stamping: Focuses on creating components with exacting tolerances and intricate designs.

How Does Progressive Die Stamping Work?

Progressive die stamping is a series of actions in punch presses. The feeding system propels a metal strip through all the stations of the progressive die stamp. Each station is a multiple stage of forming until a finished part is produced. As the press rises, the top die also moves, allowing material feed. When the press descends, the die closes and performs the stamping operation. With each stamping cycle, a finished part is removed from the die. The dies are typically made of tool steel to withstand high impact loads, maintain necessary sharp cutting edges, and resist the forces of wear involved.

Comparison of Progressive Die Stamping and Traditional Metal Stamping


When considering costs, it's important to factor in tool setup costs as well as the cost per part.

Progressive die stamps have high set up costs but lower costs per part. Compared to progressive die stamps, the setup costs for transfer die stamping and traditional stamping are lower, but the costs per part are relatively high.

Production Volume

Progressive die stamping is applied because of the capability in very large volume production. While transfer die stamps are also suitable for high-volume production, the difference is that parts are separated from the metal strip in the first operation. On the other hand, stage die stamps are well-suited for small-scale, low-volume production of fewer than 50,000 parts per year.

Tooling Lead Time

When considering project requirements, it's essential to consider the project schedule to determine which method is most applicable and cost-effective. Progressive stamping is complicated in tooling but production is very fast when tools are ready. On the contrary, traditional stamping is easier in tooling but does not have the same output rate as progressive stamping.


Typical Processes of Custom Stamping

Whether it's Progressive Die Stamping or Transfer Die Stamping, both involve a series of forming processes. Each forming operation serves a different purpose – some deepen the product, others create surface features, or remove excess material. We are familiar with the characteristics and processing features of various forming tools, having a profound understanding of their corresponding tool and die manufacturing. We can flexibly apply tooling structures and various tools combinations. Below, we introduce some commonly used forming processes.

  • Blanking: The stamping process of cutting flat shapes from sheet metal.

  • Punching: Creating holes or openings in sheet metal through a punching operation.

  • Piercing: Perforating sheet metal to produce holes or patterns.

  • Bending: Deforming sheet metal along a straight axis to create angles or curves.

  • Bottom Bending and Air Bending (Coining): Techniques for forming bends in sheet metal using press brakes.

  • Drawing: Forming sheet metal into cup-like shapes with concave or convex features.

  • Forming: Shaping sheet metal into desired contours through various bending and deformation methods.

  • Ironing: Reducing the wall thickness of a cylindrical part through axial compression.

  • Flanging: Creating a flange, or projecting edge, on a sheet metal component.

  • Embossing: Impressions or raised designs formed on sheet metal for decorative or functional purposes.

  • Curling: Rolling the edge of a sheet metal component to form a curved or rounded edge.

  • Trimming: Removing excess material or unwanted features from sheet metal components.

  • Lancing: Cutting slits or openings in sheet metal for specific design or functional requirements.
