What is Custom Metal Stamping?

Custom metal stamping is a manufacturing process that involves shaping metal into specific shapes and designs, using a combination of pressure and dies to achieve high precision and complexity. This process allows for a wide range of customization, catering to the unique needs of industries such as electronics, automotive, aerospace, and medical devices. 

Companies can produce parts that meet their specifications by employing custom metal stamping, ensuring that each component fits seamlessly into their final products.

The allure of custom metal stamping isn’t just in its precision—it’s in its ability to bring visions to life. Whether you’re looking to produce a one-off prototype or millions of components, the adaptability of custom metal stamping stands as a testament to the wonders of modern manufacturing. Stick around, and let’s delve deeper into custom metal stamping. I promise the journey is as intriguing as the process itself.

Understanding the Basics of Metal Stamping

At its core, metal stamping is a manufacturing process used to convert flat metal sheets into specific shapes. It’s a complex procedure that involves several machinery components, including presses and dies. The metal sheet is placed between the dies and subjected to high pressure, which stamps the metal into the desired shape.

The Custom Metal Stamping Process

Design and Prototyping

The first step in the custom metal stamping process is design. This stage involves converting the customer’s specifications into a detailed design plan. Utilizing advanced CAD (Computer-Aided Design) software, engineers and designers collaborate to create a digital blueprint of the part. This blueprint outlines the shape and dimensions of the part and specifies the type of metal, thickness, and any special features required.

Once the design is finalized, we move on to prototyping. Metal Stamping Prototyping is creating a working model of the part to test its functionality, fit, and durability. This is a critical phase where adjustments and optimizations are made. It’s an opportunity to identify and resolve potential issues before moving into mass production, ensuring that the final product will meet or exceed expectations.

Tooling and Die Making

After perfecting the prototype, the next phase is tooling and die-making. This step involves creating the custom tools and dies that will be used to stamp the metal parts. Dies are complex, precision-engineered molds that need to match the final part’s specifications exactly. According to the shape of the parts, we could design simple dies, progressive dies, and deep-drawn dies. The creation of dies is both an art and a science, requiring skilled artisans and precision machining equipment. The die’s quality directly impacts the stamped part’s quality, making this one of the most critical stages in the custom metal stamping process.

Stamping Techniques

Progressive Die Stamping

Progressive die stamping stands as a cornerstone in high-volume production environments. It’s characterized by a series of stations, each performing a distinct operation such as cutting, punching, bending, or coining. The metal strip moves through the progressive stamping press, with each station simultaneously performing its task on different parts of the strip.

This synchronous operation ensures high efficiency and consistency, making progressive die stamping ideal for producing large quantities of complex parts with tight tolerances. The initial cost of die development can be high, but the per-part cost is significantly reduced for large production runs, making it a cost-effective choice for many projects.

Deep Drawn Stamping

Deep-drawn stamping is a specialized technique used to create parts with a deep, hollow form, often with a depth greater than their diameter. This process involves drawing a sheet metal blank into a die by a punch and forming it into a desired shape through a series of drawing operations. Each draw operation stretches the metal into a more profound form, allowing for the creation of complex, seamless parts such as pots, pans, and casings.

Deep-drawn stamping requires precise control to maintain uniform material thickness and prevent defects like wrinkling or tearing. Its ability to produce durable, high-quality parts makes it invaluable for applications requiring robust, hollow components.


Blanking is a process in which a piece of metal is removed from a larger sheet or coil, creating a flat piece that can be further processed. It’s the initial step in producing many metal parts, serving as the foundation for further shaping and forming processes. 

Blanking is noted for its precision and efficiency, making it capable of producing clean, smooth edges crucial for the following stages of manufacturing.


Embossing involves creating raised or recessed designs on the surface of metal parts. This technique can enhance the aesthetic appeal of a part, add textural elements, or increase its structural integrity. 

Embossing is versatile, allowing for a wide range of patterns and designs to be implemented, from simple logos to complex textures.


Flanging is a process that creates flanges or rims on metal parts. This technique is essential for parts that need to be joined or connected with others. 

Flanges can provide strength at the joints, improve the part’s rigidity, or guide assembly. Flanging requires precise control to ensure that the flanges are uniform and meet the part’s specifications.


Coining is a stamping process that involves applying extreme pressure to a metal piece, causing plastic deformation over the entire thickness of the part. This technique creates detailed features, precise dimensions, and smooth surfaces. 

Coining can also work-harden the metal, enhancing its strength and resistance to wear. It’s commonly used for high-precision parts such as connectors, pins, and various components requiring exact tolerances.

Cases of Aerospace Custom Metal Stamping

One of our most challenging projects involved designing and producing a series of precision components for an aerospace client. These components were destined for use in the hydraulic systems of commercial aircraft, where failure is not an option. The project demanded materials that could withstand extreme pressures and temperatures and tight tolerances to ensure flawless operation.

Leveraging our expertise in progressive die stamping and deep-drawn stamping, we developed a multi-stage production process. This included using high-strength, aerospace-grade alloys that provide the necessary durability and resistance to environmental factors. Each component underwent rigorous quality checks, ensuring they met the exact specifications required for aerospace applications.
