You aren’t alone if you don’t know the difference between sheet metal traditional fabrication and metal stamping. Here, we would like describe these different processes and help you understand which approach is best for your parts. 

Part 1 : what is the Traditional Sheet Metal Fabrication

Precision sheet metal fabrication leverages standard tooling and equipment to create a part’s shape and features.  Traditional Sheet Metal fabrication technology are ideal for prototypes, one-off parts, and low-volume productions that don’t require custom tooling or die.

Part 2 : what is the sheet metal stamping ?

Sheet metal stamping employs metal tooling or die and specialized equipment to create a part’s shape and features. Stamping cases or parts are best for high-volume productions.

Part 3 :  Traditional sheet metal Fabrication equipment, process and capabilities

Metal fabrication workshops will provide cutting, punching, shaping, folding, welding, and custom fabrication. These powerful machines support Drsolenoid workshoip fabrication processes:

Laser cutters. Our later cutting machine offers precise cuts with minimal material waste. We can handle even complex designs in various material types and thicknesses.

Punching machine presses. The punch press employs a shaped die to quickly cut holes and other openings in your sheet metal material.

Press brakes.The press brake uses a die to form sheet metal parts, performing bending and drawing processes with high precision.

Welding machines. Our welding experts team perform spot welding with incredible accuracy, ensuring a strong, durable final product.

Part 4 :  Sheet metal Stamping equipment and capabilities

In stamping, a single press applies a series of dies customized to the part’s various angles and features. Metal stamping machines can fill an entire room, with presses ranging in size from 20-1,000 tons. You’ll find machines like these in a stamping facility:

Mechanical presses. Capable of progressive stamping, mechanical presses quickly and efficiently produce high volumes of simple, shallow-formed parts from sheet metal coils.

Hydraulic presses. Slower than mechanical presses, hydraulic presses produce deep, complex shapes in parts with extensive material flow.

Mechanical servo presses. With the flexibility of a hydraulic press and the speed of a mechanical press, the mechanical servo press offers fine controls, an array of dies, and varying production speeds.

Deep draw metal stamping presses. Also known as a “transfer press,” the deep draw press applies extreme pressure to draw a metal blank into a die and form the complex component.

Metal stamping houses make parts such as fasteners, torsion springs, hand tools, valves, flanges, rotary joints, gas fittings, and more.

Core Definitions

Part  6 . Technical Comparison

6.1  A. Process Mechanics

Stamping:

Relies on progressive dies for sequential operations (e.g., blanking → drawing → trimming).

Achieves cycle times <1 sec (e.g., Toyota’s 12,000 sph servo presses).

Limited to thickness ≤6mm (e.g., EV battery enclosures).

Fabrication:

Combines CNC laser cutting (e.g., 30kW fiber lasers), robotic bending (6-axis KUKA KR Quantec), and hybrid welding (laser-arc).

Handles 0.1–20mm thickness (e.g., SpaceX rocket fairings).

6.2  B. Tooling & Flexibility

Stamping:

Requires 50k–50k–2M molds (e.g., Tesla Cybertruck door panel dies).

Inflexible design changes (lead time: 6–12 weeks).

Fabrication:

Uses universal tooling (cost: <$5k for 90% of jobs).

Supports real-time CAD/CAM adjustments (e.g., Siemens NX integration).

Part 9 . Strategic Selection Guidelines

Choose Stamping when:

Annual demand >50k parts

Tolerance ≤±0.1mm required

Design is finalized (no revisions expected)

Choose Fabrication when:

Prototyping or low-volume production

Complex geometries (e.g., heat exchanger fins)

Multi-material assemblies (e.g., Al-Cu bimetal connectors)

Part  10 :  Traditional Sheet Metal Fabrication vs. Sheet Metal Stamping FAQ

10. 1 What are the main differences between sheet metal fabrication and metal stamping?

A： Sheet metal fabrication uses standard tooling and equipment, ideal for prototypes, one-off parts, and low-volume productions. Metal stamping employs custom tooling and specialized equipment, making it suitable for high-volume productions.

10.2  What types of parts are typically produced using metal stamping?

A : Metal stamping typically produces parts such as fasteners, torsion springs, hand tools, valves, flanges, rotary joints, and gas fittings.

10.3 How can DrSolenoid metal workship help during the design phase to avoid unexpected costs?

A : Our team offers design consultations to help identify potential design elements that could lead to preventable problems and unexpected costs. By discussing the design early, Dr Solenoid can recommend changes to improve manufacturing ability and avoid the need for costly custom tools.

10.4 What are the benefits of using a deep draw press in metal stamping?

A :  A deep draw press, or transfer press, applies extreme pressure to form complex components by drawing a metal blank into a die. This allows for the creation of deep, intricate shapes and precise bends in tiny parts that exceed the capabilities of traditional sheet metal fabrication.

10.5  What should I consider when deciding between sheet metal fabrication and metal stamping for my project?

When deciding between sheet metal fabrication and metal stamping, consider factors such as production volume, part complexity, and cost. Sheet metal fabrication is ideal for low-volume, less complex parts without the need for custom tooling. Metal stamping is better suited for high-volume, complex parts, but it involves higher initial costs due to the need for custom dies and tools. Consulting with ASM during the design phase can help determine the most cost-effective and efficient manufacturing process for your project.

Part  11 :  Conclusion

11.1 Start with a Design Consultation

The decision between stamping and sheet metal fabrication begins with a design discussion. Our team will  check your design and recommend solution changes to improve the part’s manufacturing.  If our precision metal fabrication services aren’t the right fit for your production goals, we’ll point you in the right direction.

11.2 Design considerations for sheet metal fabrication

Precision sheet metal fabrication is the way to go if your part includes traditional formed features like embossments and louvers. Remember, however, that the feature’s depth can’t significantly exceed the sheet metal’s thickness.

11.3 Design considerations for stamping

With a deep draw press, a stamping house can bypass the depth maximums that limit a fabricator. Stamping can also achieve precise bends in tiny parts under 1“.

How are these features possible? In stamping, a custom tool is made for every feature in the part’s design, enabling impressive precision on parts of every size. However, stamping tools can cost tens of thousands of dollars each, making the approach cost-prohibitive for most small or mid-sized orders.

11.4 Avoid this major design mishap

When a customer requested a quote for a small quantity of single-bend brackets , we quickly discovered an unusual challenge. Unlike the typical straight bend on most brackets, this bracket incorporated a curved bend that was impossible to achieve without a custom $13,000 tool. Predictably, the high cost of the custom tool sent the customer back to the drawing board. Avoid unexpected costs by talking with us during the design phase. We’ll help you identify design elements that could create preventable problems further down the line.

11.5 Prefer stamping: if the part needs to be mass-produced, has a complex shape or high precision, and the design is stable.

11.6  Prefer traditional sheet metal: if the part is a prototype, small batch or the design needs to be flexible, and the shape is simple.

11.7 Hybrid solution: some complex features can be preformed by stamping, and then combined with traditional sheet metal processes for post-processing (such as welding, surface treatment) .For example, automobile shells usually use stamping processes to achieve deep drawing and complex surfaces, while customized cabinets are more suitable for traditional sheet metal processing to meet personalized needs. The final decision needs to be combined with specific needs and the technical capabilities of the manufacturer.

Part 12 : Future Outlook:   

By the end of  2027, hybrid systems (stamping + fabrication) will dominate 40% of the market, driven by Indutrail requirment and renewable energy demands. Technologies like generative AI-driven process orchestration (GE Additive’s Fuse+ software) will further blur traditional boundaries between these methods.
