Many critical industry applications like those found in automotive systems, electronics, and medical devices rely on custom metal stampings. Custom stamped parts are precision-engineered to meet the high standards of performance and durability required in today’s competitive markets. But the success of your custom metal parts is decided, at least in part, long before production ever begins. In other words, the success of your metal parts all comes down to design.

Design isn’t just about achieving the desired shape or functionality — it’s about creating a part that can be manufactured efficiently, reliably, and cost-effectively. A well-designed component minimizes waste and reduces the need for secondary operations, all while maintaining the structural integrity and performance of the finished component.

Let’s take a closer look at some of the design principles that are essential for producing custom metal stampings that meet your project’s demands.

Material Selection for Custom Metal Stampings

Choosing the right material for your project is one of the first and most important decisions you’ll make when designing your custom metal stampings. A few of the most common include:

  • Stainless Steel: Known for its strength, durability, and corrosion resistance, it’s ideal for industries like medical and automotive.
  • Aluminum: Lightweight and resistant to rust, it’s a popular choice for applications where weight reduction is key, such as aerospace and electronics.
  • Brass: Valued for its excellent conductivity and aesthetic appeal, brass is often used in electrical and decorative applications.

Along with the type, the material thickness is also important. It’s part of what determines the manufacturability and performance of your stamped part. For instance, thicker materials can enhance strength and durability but may require more robust tooling and higher press force, both of which can increase costs.

Designing Custom Metal Stampings for Manufacturability

Understanding Tolerances and Clearances

Tolerances and clearances are critical for ensuring that custom metal stampings meet functional and aesthetic requirements, particularly for high-precision applications. But tolerances are one thing that can drive up production costs, so achievable tolerances that balance precision with cost is a must.

Importance of Draft Angles and Radii

Designing for manufacturability often calls for draft angles and radii to be incorporated into the design of your custom metal stampings. Draft angles allow stamped parts to be removed from dies smoothly, while radii reduce the risk of cracks and improve overall part durability.

Avoiding Common Design Mistakes

While tolerances, draft angles, and radii can improve manufacturability, there are also a few features, if included in the design, that can lead to issues like tooling damage, increased scrap rates, and part failure. Sharp corners, tight bends, overly complex features, and incomplete specifications are just a few examples.

Optimizing Part Geometry

Alongside part features, part geometry also plays an important role in manufacturability. Because complex custom metal stampings often require intricate tooling, part geometry can increase production costs and lead times. To mitigate this, it’s a good idea to simplify part design as much as possible to reduce wear on dies and improve production efficiency.

To do this, there are a few strategies that part designers and metal stamping manufacturers can implement. Eliminating unnecessary details, combining features, and standardizing dimensions where possible can both cut costs and make parts easier to assemble, reducing downstream labor expenses.

For custom metal stampings that require intricate designs or multiple manufacturing steps, progressive stamping can be invaluable. This process uses a series of stations within a single die to perform successive operations like cutting, bending, and forming as the raw material moves through the press. This enhances efficiency, consistency, and cost-effectiveness for highly complex parts. It’s also ideal for producing high volumes of identical components.

The Role of Prototyping in Design Validation for Custom Metal Stampings

Finally, prototyping is vital to ensuring the success of custom metal stamping projects. By creating a functional sample of your design before full-scale production, prototyping allows you to test form, fit, and function under real-world conditions. This can significantly accelerate the development process to allow for quicker adjustments and faster project completion. With advanced manufacturing techniques like 3D printing and CNC machining, prototypes can be produced quickly and cost-effectively, even for complex designs.

From there, manufacturers and engineers can analyze the performance of the prototype to make informed adjustments that optimize manufacturability and ensure your part functions as intended. By performing these tasks and addressing potential design flaws early, prototyping can reduce waste, minimize tooling revisions, and shorten the overall production timeline.
