Have you ever struggled with choosing the right metal forming method for precision parts? Traditional metalworking often leads to inconsistent results, wasted materials, and higher costs. Metal stamping offers a fast, highly repeatable, and cost-effective solution — but without a deep understanding of the process, it’s easy to miss its full advantages. At VMT, we specialize in combining metal stamping with metal CNC machining to deliver custom, high-precision parts. In this article, you’ll discover how metal stamping works, its benefits, limitations, and how CNC machining factories like VMT use this technology to create exceptional products.
Metal stamping is a manufacturing process where flat metal sheets are fed into a stamping press and formed into specific shapes using dies and pressure. It is widely used for producing high-volume, high-precision parts quickly and cost-effectively.
Now that you have a basic idea of what metal stamping is, let's dive deeper into how the metal stamping process works step-by-step, from tool preparation to final finishing, and why it remains a cornerstone technology for industries ranging from automotive to electronics.
Metal stamping is a cold-forming technique that transforms flat metal sheets into desired shapes using dies and mechanical force. Unlike cutting or subtractive methods, stamping manipulates material through compression and deformation, offering high efficiency and minimal waste. It is often combined with metal CNC machining when even tighter tolerances are required, providing a hybrid approach that optimizes both cost and precision.
The core of the stamping process involves feeding a flat metal strip or sheet into a stamping press where a tool and die surface forms the metal into a net shape. Whether producing simple washers or complex automotive panels, stamping enables mass production with remarkable consistency. Thanks to automation and intelligent die designs, modern stamping CNC machining parts can achieve incredible accuracy, fulfilling the tightest production requirements demanded by industries today.
How Metal Stamping Works
The metal stamping process typically begins with selecting the appropriate metal material — such as steel, copper, brass, or aluminum — followed by designing precise dies to create the desired shape. Once the design is complete, the metal is inserted into a high-tonnage press where it undergoes operations like blanking, punching, bending, and coining. Each operation manipulates the material without removing any, maintaining its strength while achieving the required geometry.
Many CNC machining factories integrate CNC machining services with stamping to refine complex features, tight tolerances, or intricate details that pure stamping processes may not achieve. This hybrid approach allows companies like VMT to deliver metal stamping CNC machining parts that meet the most demanding specifications across industries like automotive, aerospace, and medical device manufacturing.
Creating metal stamping parts is a multi-step process that requires careful planning, precision tooling, and accurate execution. Each phase — from the initial design to final post-processing — plays a crucial role in determining the quality, performance, and cost-effectiveness of the finished product. At VMT, we blend metal CNC machining and CNC machining services with advanced stamping techniques to meet the complex demands of modern industries. Let's walk through each step of the metal stamping part production process to better understand how raw metal transforms into high-precision components.
Design and Tool Preparation
The first and arguably the most critical step in metal stamping is designing the part and preparing the tooling. Engineers begin by drafting detailed CAD models that outline the part’s dimensions, tolerances, and critical features. Based on these specifications, custom dies and punches are manufactured, typically using hardened tool steel for durability.
Proper die design is crucial — it must account for material flow, strain distribution, and potential deformation to ensure the finished part meets specifications. In some cases, metal CNC machining is used to precisely cut or finish the dies, enhancing accuracy and tool life. At VMT, our expert team meticulously plans every design to guarantee superior results in stamping CNC machining parts production.
Material Preparation
Once the dies are ready, selecting and preparing the right material is the next step. Common materials used in metal stamping include steel, stainless steel, copper, brass, and aluminum, each offering unique advantages for different applications. Sheets or coils are inspected for thickness, surface condition, and mechanical properties to prevent defects during production.
In CNC machining factories like VMT, strict material standards are enforced, and traceability is maintained throughout the entire supply chain. This ensures that each batch of metal stamping CNC machining parts starts with quality-certified materials, which is essential for maintaining performance and consistency.
Feeding
Material feeding refers to introducing the metal sheet or strip into the stamping press. Automated feeders are often used in high-volume productions, ensuring continuous and precise material movement through the press. Proper feeding minimizes misalignment, wastage, and downtime.
High-end feeders can adjust for thickness variations and control tension, which is critical when combining metal stamping with CNC machining services for high-precision applications. Inconsistent feeding can cause off-tolerances that even secondary machining cannot always correct, so precision at this stage is non-negotiable.
Stamping Operations
With the material correctly fed, the actual metal stamping operations begin. Depending on the part design, multiple actions — such as blanking, punching, bending, coining, drawing, or embossing — may be performed in a single or progressive die setup. For complex components, several stamping stages may be required, each incrementally shaping the material closer to its final form.
At VMT, we specialize in integrating stamping with CNC machining services to add intricate geometries or tight-tolerance features after the primary forming process. This combination ensures that even highly complex metal CNC machining parts maintain exceptional quality and precision.
Finishing and Post-Processing
After stamping, parts often require additional finishing operations to meet surface quality, dimensional, or functional requirements. Common post-processing steps include deburring, heat treatment, surface coating, and precision machining. Especially in sectors like automotive and medical, achieving burr-free edges, precise dimensions, and flawless finishes is critical.
By leveraging our CNC machining services, VMT can seamlessly handle secondary operations, ensuring that the final metal stamping CNC machining parts meet or exceed customer expectations. This comprehensive approach reduces lead times, improves quality control, and provides customers with fully finished, ready-to-assemble parts.

High Initial Tooling Costs
One of the main drawbacks of metal stamping is the substantial upfront investment in tooling. Designing and manufacturing custom dies requires specialized skills, expensive materials, and time. For small production runs, these tooling costs can outweigh the benefits, making other methods like metal CNC machining or stamping CNC machining parts more suitable for prototypes and low-volume orders. However, for large runs, these costs are quickly amortized.
Limited Design Changes
Once the dies are manufactured, making any design changes becomes difficult and costly. Even a small adjustment might require redesigning the die or creating a completely new one. This inflexibility can be a major drawback in fast-evolving industries where product designs often need frequent updates. In contrast, metal CNC machining offers more flexibility for engineering changes without the need for complete retooling.
Thickness and Material Constraints
Metal stamping is most effective with certain materials and within specific thickness ranges. Very thick or hard metals might cause excessive die wear or even damage, while very thin materials could lead to wrinkling or tearing. In cases where material properties limit traditional stamping processes, combining metal stamping CNC machining parts with additional CNC machining services can ensure both strength and precision.
Risk of Surface Defects
During the stamping process, parts are subjected to significant pressure and friction, which can sometimes result in surface defects such as scratches, burrs, or minor deformations. These imperfections might not be acceptable in industries like medical or aerospace manufacturing. To counteract this, secondary finishing processes — including metal CNC machining and surface treatments — are often used to enhance part quality and meet strict cosmetic or functional requirements.
Not Ideal for Highly Complex 3D Parts
Although metal stamping can create a wide variety of forms, extremely complex 3D geometries often require additional processing or alternative manufacturing methods. In such cases, CNC machining services offer more precise control over intricate details, allowing for complex features like internal channels, threads, or undercuts that stamping alone cannot achieve.
Choosing the right material is a critical step in the metal stamping process. The material you select impacts not only the manufacturing efficiency but also the quality, durability, and functionality of the final metal stamping CNC machining parts. Each metal behaves differently under the high pressure of stamping, so understanding your material options helps ensure the best possible outcome.

Progressive Die Stamping
Progressive die stamping is ideal for high-volume production where efficiency and speed are critical. In this process, a strip of metal moves through a series of stations within a single die. Each station performs a specific operation—such as punching, bending, or cutting—before the part is completed. Progressive stamping is highly automated and can produce complex stamping CNC machining parts quickly with consistent quality. It is especially effective for producing intricate parts with tight tolerances at a lower per-unit cost.
Transfer Printing
Transfer printing, or transfer die stamping, differs from progressive stamping by moving the part from station to station independently, rather than moving the entire metal strip. This method is suitable for larger parts or parts that require extensive forming. Transfer printing provides flexibility in forming operations and allows for more complex geometries. In applications where metal CNC machining is needed after stamping, transfer printing ensures parts retain their integrity through each step.
Four-Slide Stamping
Four-slide stamping uses four synchronized slides to manipulate the metal from four different directions. This process is perfect for creating parts that need multiple bends or complex forms. Four-slide machines are exceptionally fast and allow for the production of complex, small to medium-sized parts with minimal material waste. When tighter precision is needed, metal stamping CNC machining parts produced by four-slide stamping are refined through CNC machining services.
Deep Drawing
Deep drawing involves pulling a metal sheet into a die to form a deep, hollow shape, such as cans, kitchen sinks, or automotive fuel tanks. It is ideal for producing parts with a high depth-to-diameter ratio. Materials with high ductility like aluminum and stainless steel are commonly used. Deep drawn parts often benefit from metal CNC machining for final dimensioning and surface finishing to meet stringent application standards.
Fine Blanking
Fine blanking is a specialized process for creating highly precise parts with smooth edges and tight tolerances. Unlike traditional stamping, fine blanking uses higher pressure and triple-action tools to shear the metal cleanly. This method is used for automotive gears, transmission parts, and other critical components where performance and precision are essential. Fine blanked parts often integrate CNC machining for finishing or further detail work.
Deep Stamping
Deep stamping, similar to deep drawing, focuses on forming large and complex hollow parts. It is particularly effective for producing components requiring durability and strength, such as aerospace and automotive structural parts. Deep stamped parts are often supplemented by CNC machining services to enhance detail, maintain tolerances, and improve surface quality.
Hydraulic Forming
Hydraulic forming uses pressurized hydraulic fluid to shape metal sheets into complex forms. This method allows for deep and intricate designs that would be difficult or impossible with traditional stamping. Hydraulic forming is often used in aerospace and automotive industries for high-strength, lightweight parts. After forming, parts may go through metal CNC machining to achieve exact specifications.
Blanking
Blanking is one of the most basic metal stamping processes where a punch and die are used to cut out flat shapes from a sheet of metal. The resulting blanks can then be further processed or used as final parts. Blanking is often the first step before additional CNC machining services refine the part’s dimensions and surface characteristics.
Coining
Coining is a precision metal stamping process used to create fine details, embossed features, or high-density areas in a metal part. It involves high pressure that flows the metal into a precise shape without cutting. Coining is ideal for creating features like coins, badges, and specialized fasteners that require tight tolerances and a high-quality finish.
Punching
Punching involves cutting holes or shapes into a metal sheet using a punch and die. It's a fast and cost-effective method, perfect for parts with multiple perforations. After punching, parts often undergo CNC machining to clean up edges or add finer details if needed.
Embossing
Embossing raises or recesses parts of the metal surface to create designs, logos, or textured finishes. This process enhances the aesthetic and functional qualities of a part, especially in decorative applications. Metal stamping CNC machining parts that require both embossed features and precision fits often combine embossing with metal CNC machining for the best results.
Bending
Bending is a simple but essential metal stamping process where metal sheets are deformed into angles, U-shapes, V-shapes, or channels. It’s widely used across industries from construction to electronics. When exact angles or multiple bends are needed, bending is often combined with CNC machining services for precise results.
When planning a metal stamping project, understanding production volume needs is critical.

The right tools enable CNC machining services providers to create intricate and complex parts for various industries, such as automotive, aerospace, and electronics.
Stock Strip Layout and Design
Before the stamping process begins, a detailed stock strip layout must be created. This involves designing the layout of the raw material (typically a metal sheet or strip) on the die to minimize material waste while ensuring that each stamped part is optimally positioned for production. The layout should also consider factors like the number of parts to be stamped from each sheet, the thickness of the material, and the specific requirements of each part. Metal CNC machining can further refine the stamped parts to meet precise tolerances.
Tool Steel and Die Set Processing
The tool steel used for dies is one of the most important factors determining the longevity and performance of the stamping operation. High-quality tool steels are selected based on their resistance to wear, impact, and thermal expansion. The die set, which holds the dies in place, must be designed with the utmost care to ensure that it can withstand high-pressure forces without deforming or compromising the accuracy of the stamped parts. Proper CNC machining of die sets ensures that they are aligned perfectly and capable of withstanding the stresses involved in stamping operations.
Secondary Operations
Secondary operations refer to additional processes that may be necessary after the initial stamping to achieve the final part design or to refine certain features. These can include operations such as CNC machining, tapping, drilling, or surface finishing.

To stamp metal by hand, you need basic tools like a hammer, metal stamp, and anvil. Position the metal on a flat surface, then apply pressure with the hammer on the stamp to imprint the design. This method is limited to smaller, simpler designs.
4. What are the 7 steps of the stamping method?
The typical steps in the metal stamping process are:
5. What is the easiest metal to stamp?
The easiest metals to stamp are generally aluminum and copper, as they are softer and easier to manipulate compared to harder metals like stainless steel or titanium. These softer metals require less force to stamp, making the process quicker and more efficient.
6. What is the difference between engraving metal and stamping metal?
Engraving involves cutting or etching into the surface of the metal to create designs, while stamping involves using pressure to form shapes, create holes, or imprint designs into metal. Engraving is often more detailed, while stamping is typically used for shaping and forming.
7. What machines are used for stamping?
Common machines used for metal stamping include mechanical presses, hydraulic presses, and servo presses. These machines apply high pressure to shape the metal, depending on the type of stamping required.
8. Is metal stamping difficult?
Metal stamping can be complex, depending on the material, design, and precision required. However, with the right equipment, experience, and process optimization, it can be made relatively straightforward, especially for high-volume production runs.
9. What are the alternatives to metal stamping?
Alternatives to metal stamping include laser cutting, waterjet cutting, die cutting, and 3D printing. Each method has its advantages and disadvantages depending on factors such as the material, part complexity, and production volume.
10. Can I stamp stainless steel?
Yes, you can stamp stainless steel, although it requires more force and specialized tools due to the material’s hardness. Stainless steel is commonly stamped for applications that require durability and resistance to corrosion.
11. How can I make my own stamp at home?
To make your own stamp at home, you’ll need a suitable stamping die, typically made from a soft metal or plastic for smaller projects. You can carve or etch the design into the die using specialized tools. However, for metal stamping on tougher materials, industrial machinery is necessary.
12. What are the four types of metal stamping?
As previously mentioned, the four main types of metal stamping are:
13. Which is better, etching or engraving?
Engraving is better for producing deeper, more detailed designs on metal, while etching is ideal for surface-level designs. The choice depends on the project requirements, including depth, precision, and material type.
14. What metal is suitable for stamping?
Common metals used for stamping include steel, aluminum, brass, copper, and stainless steel. The material should be malleable enough to withstand the stamping process without cracking or breaking.
15. How thick can you stamp metal?
The thickness of the metal that can be stamped depends on the stamping equipment and process used. Typically, metals ranging from 0.1 mm to 10 mm thick can be stamped, but thicker materials may require more specialized techniques or equipment.
