What is Metal Stamping?
Metal stamping is a manufacturing method that shapes metal into precise parts using special tools called dies and machine such as presses. It is a cold-forming process that shapes metal without heating it. This technique can work on different metal material such as plates, strips, tubes, and profiles.
There are several stamping techniques including blanking, punching, embossing, and more. These methods can be used alone or combined depending on the part design. This manufacturing process can produce large numbers of identical parts quickly. Thus, making it ideal for mass production.
Metal Stamping Process
The process usually starts with metal in the form of coils or flat sheets. These are fed into a stamping press that holds a die set designed for the part’s shapes. When the press is activated, it applies a strong force that makes the die cut, bend, punch, or emboss the metal into desired form.
Some parts can be made in a single step. More complex parts may require several stages, especially when using progressive dies. This flexibility allows manufacturers to produce simple flat shapes to intricate and more detailed components with consistent quality.

Metal Stamping Process and Techniques We Provide
DSR offers a complete range of metal stamping techniques to ensure high-quality, durable, and high-precision parts for your projects.
Progressive stamping uses multiple dies arranged in sequence. This allows the metal to go through several shaping steps in a continuous process. With this method, we can produce deeper parts with different shapes.
- High-volume production
- Automotive components manufacturing
- Reduced production time
We use this process to create parts requiring deep cavities. The extreme shaping of the metal compresses its structure. Thus, creating a more rigid components. This also helps us produce a stronger part.
- Enclosed boxes and cylinders
- Metal containers
- Casings
Fourslide stamping forms parts from four different directions instead of just one. This allows us to create more complex shapes and intricate details. We also use this method for small precision parts such as battery contacts, electronic connectors, etc.
- Offers design flexibility
- Faster production time
- Lower manufacturing cost
In this method, metal sheets are placed over a die with the desired shape at the bottom. A high-pressure bladder presses the sheet into the shape of the die.
- Multiple parts can be formed at the same time
- Quick and accurate method
- Finished parts need to be trimmed
This process cuts out flat metal pieces from a sheet before they are shaped. It has a variation called fineblanking that creates a very precise cuts with smooth edges and flat surface.
Coining is a type of blanking that creates small and round parts by applying force. This not only shapes the part but also hardens the metal and removes burr or rough edges to give clean finish.
Punching removes unwanted sections from a metal sheet. Unlike blanking, where the cut-out piece is the product, in punching remaining sheet is the final part.
Embossing creates a raised 3D design on the surface of the metal. This is done through a series of depressions and is often used for decorative purposes
Bending shapes the metal in a single axis. This forms U, V, or L profiles. The process involves clamping one side of the material and bending the other over or against a die.

Low-Volume Stamping Services
Production runs for our low volume stamping services is up to 100,000 units. Projects should start at a minimum of 1,000 pieces for cost-efficiency.
If your business needs smaller orders such as bridging the gap between prototype and full-scale production, low-volume production is best for you without committing to large quantities.
Low volume runs help keep the per-unit cost reasonable while allowing for design adjustments before mass production.
Medium-Volume Stamping Services
If you choose medium-volume stamping services, production will start between 100,000 to 1,000,000 units. It offers the same flexibility found in low volume orders but with lower price per part due to larger quantity.
The upfront tooling costs are lower compared to high-volume runs. Thus, making it an effective choice if your business need more parts than a small batch but still want to control costs.
Short Run Stamping Services
Our short run stamping services are a low-volume production method. It is designed for quick turnaround at the lowest cost.
It typically involves minimal tool revisions and requires fewer changes to the process or equipment. This makes it ideal for parts that need less design flexibility or if you are testing a new product in the market.
DSR short runs stamping services deliver fast results and cost-savings with no changes during production.
Long Run Stamping Services
DSR long run stamping services offers the highest flexibility in the production process. In this method, various factors such as materials, machine settings, and tooling can be adjusted as needed.
While this may increase costs compared to short runs, it ensure consistent quality and can achieve extremely high output per minute.
The low per-unit cost and ability to produce large quantities make it perfect for on-going production needs.
Stamping Services Material Options
Aluminum is a material commonly used in stamping process due to their lightweight and good machinability. Stamped aluminium parts are commonly used in electronic, aerospace, and automotive industry. Typical grades include:
- 5052
- 6061
Steel is a popular material with durability and high strength. This makes it ideal for various stamping processing. We can create stamped parts using different steel variations:

Post-Processing Options for Metal Stamped Parts
DSR offers post-processing such as surface treatments to finished stamped parts. This help improve the surface qualities, appearance, functionality, and mechanical properties.
This surface finishing can improve the stamped parts resistance to corrosion. It also helps in improving the part hardness and wear resistance. This is typically applied to aluminium stamped parts and can provide smooth/matte finish with different colors such as clear, grey, gold, and more.
In this post-processing, dry powder is applied to the stamped part as a protective coating. This coating is applied to the stamped part using electrostatic method. Powder coating is applied to aluminium, steel, and stainless steel parts. It comes with any colors and gloss or semi-gloss texture.
Electroplating surface finish is applied to the stamped parts as a decorative coating, enhance corrosion, or improve functionality. Electroplated stamped parts are commonly used for aerospace industries. This can be applied to aluminium, stainless steel, and steel stamped parts.
It is a post-processing technique used for stamped parts to provide a satin finish. This treatment is mainly used for aesthetic purposes. It can used for steel, aluminium, brass, ABS, and stainless steel stamped parts.
Polished stamped parts have shiny and smooth surface. This is commonly applied to aluminium, stainless steel, steel, and brass stamped parts.
Sand blasted stamped parts typically have smooth surface or matte texture. It is mainly used for ABS, aluminium, and brass stamped parts. This also serves as a base for other surface treatments.
