Compared with other mechanical and plastic processing methods, precision metal stamping processing has many unique advantages in terms of technology and economy.

The main manifestations are:

(1) Precision metal stamping parts have high production efficiency, are easy to operate, and are easy to achieve mechanization and automation. This is because stamping relies on stamping molds and stamping equipment to complete the processing. The number of strokes of a regular press can reach dozens of times per minute, while high-speed pressure can reach hundreds or even thousands of times per minute, and each stamping stroke can result in a stamped part.

(2) When stamping, because the die ensures the accuracy of the size and shape of the stamping parts, the surface quality of the stamping parts will not be damaged generally, the die life is generally long, the stamping quality is stable, the interchangeability is good, and it is "exactly the same".

(3) Stamping can process parts with a wide range of sizes and complex shapes, such as small watches and stopwatches, large car longitudinal beams, cover plates, etc. In addition, the cold deformation and hardening effects of the material during the stamping process result in high stamping strength and stiffness.

(4) Stamping generally does not produce chips and debris, consumes less material, and does not require other heating equipment. It is a material saving and energy-saving processing method, and the cost of stamped parts is relatively low.

The processing of precision metal stamping parts is a production technology that utilizes the power of conventional or specialized stamping equipment to directly deform the sheet metal through the deformation force inside the mold, thereby obtaining a certain shape, size, and performance of the product parts.

Sheet metal, molds, and equipment are the three elements of stamping processing, which is a cold deformation processing method for metals.

Therefore, it is called cold stamping or sheet metal stamping, abbreviated as stamping. It is one of the main methods of metal plastic processing (or pressure processing) and also belongs to material forming engineering technology. In order to meet the requirements of the shape, size, accuracy, batch, and raw material properties of stamped parts, various stamping processing methods are used in production.

In summary, stamping can be divided into two categories: separation process and forming process

1. Separation process: The separation process refers to the process of separating the blank along a certain contour line to obtain a stamped part with a certain shape, size, and cross-sectional quality.

2. Stamping forming: The forming process refers to the plastic deformation of the billet while continuously cracking, resulting in a stamped part of a certain shape and size.
