Advantage and Disadvantages of Metal Stamping
Before you choose metal stamping as your manufacturing process, it is crucial to understand what benefit you will get and what the pullback is.
Advantages of Metal Stamping
Stamping is excellent for mass-producing complex parts. Its benefits include:
- Ability to create complex shapes and contours.
- Suitable for large-scale production, ranging from thousands to millions of parts per year.
- It uses techniques like fine blanking to work with thick metal sheets.
- Offers low costs per piece, making it economical.
Disadvantages of Metal Stamping
Metal stamping, while efficient for large-scale production, does have certain drawbacks due to the necessity of producing dies first:
- Extended Lead Times: The initial production of parts can be delayed due to the time required to create the necessary dies.
- High Initial Costs: Upfront expenses are significant and driven by tooling, check fixtures, and engineering efforts to set up stamping production lines.
- Die Design Iterations: Suppliers may need to refine the die design multiple times before production starts to guarantee that products meet specifications reliably. This iterative process can further delay production.

- Powder Coating adds a tough, protective layer that resists chipping, scratching, and fading. It is available in various colors.
- Chem Film: Particularly beneficial for aluminum stamped parts, this coating enhances corrosion resistance and ensures better adhesion for subsequent painting.
- Anodizing strengthens the surface of non-ferrous stamped parts, like aluminum.
- Plating: Gold, silver, and electroless nickel plating not only improves the visual appeal but also increases the corrosion resistance and electrical conductivity, making the stamped parts suitable for more demanding applications such as in electronic or automotive industries.
If you need a post-processing option not listed here, please contact us for more information.
As the machined or deburring
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Smooth machining
Smooth machining is done by controlling the machining process, such as feed rate & cutting speed. It minimizes the tool marks and risk of corrosion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Fine machining
The higher-precision machines produce delicate machining surfaces by utilizing sharper tools and regulating feed rate and cutting speed. Surface roughness up to Ra 0.8 μm can be maintained with smooth machining.
More
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

Technology Overview
Introduction
Metal stamping is a manufacturing process in which flat sheets or coils of material are shaped into specific forms. With Stamping, different shapes can be made out of the sheet metal by pressing down on it inside the die. According to your stamping drawing, Prolean is the best place to get the exact shape. We use a full-automated and computer-controlled Stamping process to create quality parts.
What is Stamping?
Stamping is a process in which sheet metal is converted into a pre-defined shape. The stamping die gives the shape of the sheet metal using pressure. So, the sheet metal is fed into the Die, and applied pressure will shape and shear the material into the desired final part, making it more affordable to manufacture several identical parts from sheet metal by stamping.
Types of Stamping
Progressive Stamping is performing numerous stamping operations sequentially using a sequence of workstations. Since diseases endure a long time with this procedure, identical parts can be made over an extended period. In addition, it also produces significantly less scrap. Transfer stamping is commonly used to manufacture large parts. After one operation is finished, the part is transferred to another workstation. With Fourslide, Four tools can be used simultaneously to shape the four slides of a workpiece. It allows for the formation of parts with complex geometries.
Deep-drawing stamping is perfect for manufacturing components with multiple diameters. It entails using a punch to pull a sheet into the Die and mold it there.
Advantages
Compared to other typical manufacturing processes, Stamping is more automated. It is also cost-effective to make high-quality identical items because the die can be used repeatedly. Additionally, it makes surface polishing or post-processing simpler.
Stamping Process
The first phase involves designing the Stamping dies according to the required operations, typically using CAD/CAM technology. For the stamping process to be accurate and for each stamp to retain the ideal component quality, a tight tolerance of dies is also essential
Specific Techniques for the Stamping Process
Under the stamping approach, numerous techniques include punching, blanking, flanging, embossing, bending, and more.
Punching and blanking are used to create the hole in the workpiece. Embossing refers to the raised or recessed design in the sheet metal while flagging is used to produce the flange structure. However, there is one thing common in all techniques: Die and pressure are involved, no matter whether they are associated with creating a hole, flange, recessed design, or bend.
