It is well known that metal stamping is a technology well suited for high volume production. So do you know what is metal stamping process?
This guide introduces you to the main types of metal stamping and the actual process and steps involved in stamping. By reading this article, you will have a clear idea about metal stamping technology.
Metal stamping is a manufacturing method for producing thin sheet products or parts. The metal stamping process requires the use of a specialized press and a stamping die (a pre-designed tool). Metal stamping allows different types and sizes of metal to be pressurized and stamped through a machine to produce different shapes of parts or products in a cold working process.
What are the Advantages of Metal Stamping?
Metal stamping is a well-established manufacturing process that is widely used in the automotive, home appliance, electronics, and aerospace industries. Its advantages are very obvious in mass production and complex parts manufacturing.
High Productivity
Metal stamping is a very highly automated process, capable of producing large quantities of parts in a short period of time.The stamping process is often very fast, especially when automated production lines are used, and can operate 24 hours a day.
The stamping process is often very fast, especially when automated production lines are used, which can work 24 hours a day. When automated production lines are used, 24-hour operation is possible.
High Precision and Consistency
DYB Stamping uses very advanced precision molds and automated equipment, which allows us to produce parts with very high precision. Due to the high precision in the design and manufacture of our molds, the shape and size of the parts are very consistent from one stamping to the next, reducing errors caused by human intervention.
Adaptable and Diverse Materials
Metal stamping is applicable to almost all types of metal materials, including steel, aluminum, copper, nickel alloys, stainless steel, and more. We can choose the right material according to your project needs. In addition, the stamping process can be combined with other manufacturing processes to further enhance the functionality of the part.
Cost-effective
Because the metal stamping process is capable of high volume production and is highly productive, the production cost of individual parts is relatively low. While the design and manufacture of the tooling requires some upfront investment, once the tooling is completed and put into production, the cost of production drops significantly. As a result, metal stamping is well suited to high-volume, low-cost production needs.
Environmentally Friendly
Compared to other manufacturing processes, such as casting or welding, metal stamping is more environmentally friendly in terms of energy consumption and waste generation. Scrap generated during stamping is typically low and can be recycled to further minimize the environmental impact.

What are the Four Types of Metal Stamping?
There are four main types of metal stamping:
- Bending
- Deep Drawing
- Blanking and Piercing
- Flanging
1. Bending
Bending is a metal forming process. This process essentially involves bending a sheet of metal into a desired angle or shape by applying force to it. This is usually done using a press or bending machine.
The process of Bending involves placing the material between molds or bending machines, and then the upper die or pressure tool applies downward pressure to bend the sheet metal along the shape of the mold.
Bending is often used to make structural parts such as L-shaped stampings, U-shaped stampings and Z-shaped stampings.
2. Deep Drawing
Deep drawing is a metal forming process that is often used in the mass production of thin-walled containers and shells. deep drawing forms deep cavities or cylindrical parts by pressing a sheet of metal into a mold. This process is suitable for parts with complex shapes and high depth-to-width ratios.
Deep drawing is capable of molding complex parts in a single pass, with high efficiency and low scrap rates. It is often used for the manufacture of cans, cups, automobile mailboxes and household appliance components.
3. Blanking and Piercing
Blanking and piercing both belong to the basic types of stamping processes, and they can both be referred to as cutting processes. the difference between them is mainly the goal of the operation and the purpose of the operation.
In the blanking process, a die cuts a fully shaped part through the fit of a punch and die, and the remainder is discarded. The cut part is usually used as a base part for further processing or assembly.
The Piercing process uses a punch and a die in conjunction to cut holes into specific areas of the sheet metal. The punched metal scrap (often called slug) is discarded.
4. Flanging
Flanging is a stamping technique that bends or folds metal edge sections into a specific shape. The main purpose is to increase the structural strength of the part, improve durability or make it more suitable for subsequent assembly.
Flanging applies a mechanical force to the edge area of a sheet or plate of metal, causing the plate to bend outward or inward to form a continuous edge, usually at a right angle or other shape. If the edge of the metal is turned outward, it is called flanging and is often used to reinforce external structures. If the edge of the metal is turned inward, it becomes an inward flap and is typically used to form a seal or joint.

What Are the 7 Steps in the Stamping Method?
Metal stamping is often used to make precision parts in the automotive, electronics, and appliance industries. By placing a sheet of metal in a mold, pressure is applied to shape the metal. The following is 7 steps of metal stamping process.
1. Material Preparation
Before we can officially proceed with stamping production, we need to select the sheet metal that perfectly meets the needs of your project. This will ensure that the metal stamping parts produced have the right thickness, hardness and strength. The material is then cut and machined to a size suitable for stamping. This process needs to be chosen based on the shape, size and production lot of the part.
It is important to note that the cut sheet metal needs to be deburred and the surface cleaned so that it does not interfere with subsequent processing.
2. Die Design and Manufacturing
After selecting the material, our engineers will design a suitable stamping mold according to the drawing of the product.
The design of the mold is very important. It directly determines the molding effect during the stamping process, so the shape of the product, accuracy, production batch, and the capacity of the stamping machine must be taken into consideration. After the design is completed, the mold is made by processing and installed and debugged.
In the process of mold design, it is necessary to consider the complexity of the stamped parts mechanical characteristics of the stamping process (such as tension, bending, shear, etc.).
3. Die Installation
After the mold design is completed, the fabricated mold is mounted on the press and the precision and alignment of the mold is ensured.
This step needs to ensure that the fit between the mold and the press is very precise to avoid processing errors caused by improper installation.
4. Stamping
By this point, the preparation work before stamping is all completed. The next step is to formally enter the stamping production process.
The operator only needs to put the metal sheet into the installed mold and start the stamping machine to carry out the stamping operation. In this process, through the action of the mold and the punch, the metal sheet will be plastic deformation, molded into a predetermined shape. Specific stamping methods can be punching, stretching, bending, shearing, etc.
During the stamping process, the operator needs to precisely control pressure, speed and temperature. This is effective in avoiding cracks, stretching or deformation of the metal material.
5. Deburring and Trimming
Burrs may occur on the edges of stamped parts in holes or cut sections. In order to ensure a smooth surface of the part, we need to deburr these burrs which need to be removed by a deburring process.
6. Inspection and Quality Control
All metal stampings purchased from DYB Stamping are subjected to rigorous dimensional and quality checks to ensure they meet design and technical requirements. Our quality control includes cosmetic inspection, dimensional inspection, and functional testing.
7. Assembly and Packaging
Once the part is stamped, deburred, trimmed and passes quality inspection, it is ready for assembly or final processing. We will package according to the customer’s needs.
