About the CNC Punching Process
CNC punching is a precise and efficient sheet metal fabrication method that uses a turret punch press controlled by computer software. The machine drives hardened tools down onto the sheet to create holes, slots, louvers, or custom shapes. It can perform single hits or continuous nibbling to produce complex patterns.
This process is well-suited for cold-rolled steel, stainless steel, aluminum, and galvanized sheets, typically up to 6mm thick. It’s ideal for mid- to high-volume production due to its speed and repeatability. Tolerances are usually within ±0.1mm, depending on material and tooling.
CNC punching is often used for enclosures, brackets, panels, and other parts requiring multiple cutouts. It supports both prototyping and mass production with fast setup times and lower tooling costs compared to stamping dies.

Applications of CNC Punching Services
CNC punching is a versatile and reliable process used to manufacture precision sheet metal components across a wide range of industries. It is especially effective for parts that require multiple holes, slots, louvers, or embossed features in a single setup.
Typical applications include electrical enclosures, switchgear panels, server racks, HVAC covers, mounting brackets, and machine guards. The process is also commonly used for metal furniture components, automotive hardware, and telecom equipment panels.
Due to its speed, accuracy, and cost-efficiency, CNC punching is ideal for both prototyping and large-scale production. Industries such as electronics, industrial automation, transportation, and construction depend on CNC punching to produce consistent, high-quality parts with tight tolerances and complex geometries.
Metal Finishes for CNC Punch Services
At Shengen, we know that the finish of a part matters just as much as its shape. That’s why we offer a wide range of finishing services to protect your CNC punched parts, improve how they look, and keep their size and precision intact.
Our Finishing Services Include:
- Powder Coating – Strong, colorful coating with great resistance to UV rays and chemicals
- Electroplating – Options like zinc, nickel, or chrome for better conductivity and wear resistance
- Anodizing (for Aluminum) – Hardens the surface and adds optional color for corrosion resistance
- Brushed or Satin Finish – Smooth, lined surface for a clean and modern look
- Bead Blasting – Creates a matte surface that helps paint or powder stick better
- Passivation (for Stainless Steel) – Cleans the metal to improve corrosion resistance
- Phosphating – Helps paint stick better and adds light rust protection
- Laser Etching – Adds permanent markings like logos, barcodes, or instructions
The Process Flow & Duration Estimation
Please note that the final cost depends on the customized service you require, the specifications of the raw materials used, the relevant national laws, and the distance of transportation. Take the example of booking a tall container of products:
Step 1: Drawing Design (within 1 day)
Designers use CAD to quickly as well as accurately modify designs to meet the desired specifications, ensuring that the final product meets the required specifications quickly and accurately.
Step 2: Product Proofing (1-2 days)
Product proofing is an essential part of the manufacturing process that can help businesses ensure the quality and consistency of their products while minimizing risks and costs associated with defects or errors in production.
Step 3: Bulk Manufacturing (1-3 days)
Once the specifications and quality of the product are confirmed to be in order, it is ready for mass production.
Step 4: Shipping (3-5 days)
Once the products arrive at their destination, you will receive an alert. You can plan how to collect your shipped goods.
