Metal Blanking

Metal blanking means a blank with dimension determined by the target end product, is punched out from the metal sheet by punching machine. As a professional metal processing factory, Hunkmachining provides quality custom sheet metal blanking services for customers all over the world. Feel free to contact at any time.

Sheet Metal Blanking Services Features

  • The sheet metal blanking process is easy to realize mechanization and automation with high productivity and simple operation, which leads to low cost.

  • Sheet metal blanking can punch parts with complex shapes without cutting and with less waste. Therefore raw materials and energy consumption can be saved.

  • High precision, low surface roughness, stable size and good interchangeability.

  • Die manufacturing is complex and costly, thus its advantages mentioned above are prominent only under the condition of mass production.

Sheet Metal Blanking Process

During the metal blanking process, the metal sheet is generally placed on the female die and pressed downward by the male die. Then, the blank with the required shape and size is sheared out by the convex edge of the die while pressing. Sometimes the finished product can be obtained by blanking at one time. Different types of sheet metal blanking encompass a variety of techniques used in the manufacturing industry to shape and cut metal sheets into desired forms. Blanking is a process that involves the removal of unwanted material from a metal sheet to create specific shapes or outlines. Target metal blanking finds extensive application in various industries such as automotive, aerospace, and electronics.


Punching is another type of sheet metal blanking technique. It involves the use of a punch and die set to create holes or intricate shapes in metal sheets. Punching is widely used in the production of electrical connectors, brackets, gaskets, and other components that require precise perforations. This metal blanking process can be automated, making it highly efficient for mass production.


Shearing is one prevalent method of metal blanking. It utilizes a specialized tool called a shear to cut metal sheets. This technique is suitable for straight cuts and is commonly employed to produce simple shapes like squares, rectangles, and circles. It is a cost-effective and efficient sheet metal blanking process for creating basic metal components.

Laser Cutting

As a pro metalworking factory, Hunkmaching also provides laser-cutting services for our customers. Laser cutting is a popular method in sheet metal blanking for complex shapes and contours. This technique employs a high-powered laser beam to accurately cut through metal sheets, allowing for intricate designs and smooth edges. Laser cutting is especially advantageous for applications in industries such as jewellery, signage, and architectural metalwork, where precision and fine details are crucial.

What Is The Difference Between Metal Blanking And Punching Holes?

Punching is to punch a hole in the plate to obtain a workpiece with a hole. The material removed is scrap. The remaining material is the target product. On the other side, the sheet metal blanking service is to achieve blanking parts with a particular shape and size. The removed part is the finished product and the remaining material is the scrap.

Metal Blanking Applications

Metal blanking's versatility and precision make it an essential manufacturing process across diverse industries. Its applications range from large-scale components in the automotive and aerospace sectors to intricate and precise components in electronics, medical, and consumer goods industries.

Sheet Metal Blanking Services Material Selection

When it comes to sheet metal blanking, selecting the best material is crucial for ensuring successful manufacturing processes and high-quality products. here are several common materials and their advantages in metal blanking services:

Steel: Steel is widely regarded as one of the best materials for blanking due to its exceptional strength and formability. During the steel metal stamping, various types of steel are available, including carbon steel, stainless steel, and alloy steel, offering different advantages. Carbon steel is known for its affordability and excellent machinability, making it suitable for structural components and general parts. Stainless steel exhibits excellent corrosion resistance, making it ideal for applications requiring protection against rust and oxidation. Alloy steel provides higher strength and wear resistance, making it suitable for demanding applications.

Aluminium: Aluminium is a lightweight material that offers good strength and excellent formability. it is widely used in industries such as automotive, aerospace, and electronics. aluminium's lightweight nature makes it an excellent choice for weight reduction, while its formability allows for the creation of complex shapes. Aluminium alloys, such as 6061 and 5052, are commonly used in sheet metal blanking services due to their excellent formability and corrosion resistance.

Copper: Copper is valued for its excellent electrical conductivity and thermal properties. Copper sheet stamping is often used in electrical components and heat exchangers. Copper is highly malleable and easy to work with during the blanking process. Custom copper stamping also offers good corrosion resistance, making it suitable for applications that require resistance to corrosion.

Titanium: Titanium is known for its exceptional strength-to-weight ratio, excellent corrosion resistance, and biocompatibility. It finds applications in industries such as aerospace, medical, and chemical. Due to its lightweight yet high-strength properties, titanium is preferred for applications that require both strength and weight reduction. Its corrosion resistance makes it an excellent choice for environments where protection against corrosion is essential.
