Punching – Fast & Cost-Effective Sheet Metal Processing
Punching is a high-speed sheet metal process that uses a punch press to create holes, cutouts, and special shapes with great accuracy. It is widely used for functional and decorative features in prototypes and low-to-medium volume production. With punching, complex patterns can be achieved in seconds, offering:
Whether you need simple perforations or complex geometries, our punching service ensures high-quality results with fast turnaround.
How Punching works？
Punching is a metal forming process that uses a punch press to force a tool (called a punch) through a sheet of metal to create a hole or shape. The punched-out piece is usually scrap (called a slug), while the remaining sheet becomes the part.

Punching Design Guide
The design of stamped sheet metal parts is often complex. To help integrate them smoothly into your next project, the following outlines key manufacturability considerations to keep in mind during the design process. These guidelines will help reduce project costs, improve production efficiency, and ensure consistent, high-quality parts.
- All forming features should be oriented consistently. Designs that incorporate both upward and downward forming features are prone to quality issues.
- The distance between holes should generally be 1.5 times the material thickness. For soft materials or when using a multi-hole (cluster) punch, the hole spacing can be reduced to 1.2 times the material thickness. However, when using a single-hole punch, a larger spacing is required to ensure consistent hole quality.
- The minimum hole diameter should be designed as 1.2 times the material thickness.
- The number of unique punch features with different sizes or shapes in the design should be minimized. Using features of the same size can reduce mold setup and adjustment time, potentially lower tooling costs, and improve both production efficiency and the consistency of part quality.
- The tolerances for stamped features should be maintained within ±0.127 mm. It is important to note that the dimensional tolerances in the flat state differ from those in the formed state. Therefore, design considerations should account for both conditions to ensure part assembly accuracy and manufacturability.
Assembly service
Although sheet metal parts with stamped features can be used as independent components, in practical industrial applications they are more commonly integrated into assemblies, subassemblies, or welded units to form fully functional components. To streamline the implementation of your project, we offer the following professional assembly services, ensuring that delivered components can be immediately used in subsequent operations:
-
Precise hardware installation
-
Welding services
-
Riveted assembly
The assembly process typically adds 1–3 days to the base production cycle. The exact duration will depend on factors such as the number of components, assembly complexity (e.g., multi-step operations, high-precision positioning requirements), and other project-specific details. We will confirm the precise timeline with you in advance based on the specifics of your project.
Surface Finish and Post-Processing Options
As machined
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.
Alodine
Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.
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.
Sanding
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Electroless Nickel Plating
A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.
Chrome Plating
Chrome plating is widely used in various industries, which not only enhances the beautiful appearance of the product, but also improves the performance of the product, such as corrosion resistance, oxidation resistance, abrasion resistance, hardness, etc.
Passivation
Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.
